Besides that we also discuss about the objective of our study and the questions that we researched about. These all are commonly surveyed about the topics like the factors, solutions and effects of urban flooding. At the end of introduction part, there will be the definition of some important terms in our study. 1.2 Background information Urban flooding means a large quantity of water is overflowing and inundating cities or town. Urban flooding is an inevitable problem for many cities around the world. The problems arising from urban flooding range from minor ones, such as water entering the basements of a few houses, to major incidents, where large part of cities are inundated for several days. Most modern cities in the industrialized part world usually experience small scale local problems mainly due to insufficient capacity in their sewer systems during heavy rainstorms. Cities in other regions, including those in South/South-East Asia, often have more severe problems because of much heavier local rainfall and lower drainage standards. This situation continues to get worse because many cities in the developing countries are growing rapidly but without the funds to extend and rehabilitate their existing drainage systems. A few examples of historic urban flood problems are Mumbai (India), 2000 where nearly 17,000 telephone lines in Mumbai City ceased to function after flooding occurred and electric supply was cut off for safety purposes. The water depth reached 1.5 m at the worst inundated locations and 15 lives were lost in the flood. In Dhaka City (Bangladesh), even a small amount of rain may cause serious problems. Dhaka has often experienced flooding with ankle to knee-deep water in the streets. In September/October 1996, most of the daily activities in Dhaka were nearly paralyzed and heavy traffic jams occurred due to 15 stagnant water. In 1983, Bangkok (Thailand) was flooded for nearly 6 months and it caused the loss of life and infrastructural damages of approximately $146 million (AIT, 1985). In February 2002, five people were killed in Jakarta (Indonesia) as heavy rain extended floods to the city centre, deepening a crisis, which forced 200,000 people from their homes and killed 50 nationwide (Bangkok Post, 3rd February 2002). A final example is Houston, Texas (USA)—where the storm ‘Allison’ in June 2001 caused urban flood damages in the order of $2 billion on the Texas Medical Centre in the Harris Gully watershed (Holder et al., 2002). Therefore, we need to find a solution to solve this problem from becoming worse. We need to ensure that incidents like this can be reduced because this problem involves many parties. This problem also has several adverse effects to humans and the environment. 15 1.3 Objective of the study The objectives of this study are: 1. to investigate the reasons of urban flooding when raining. 2. to identify the effects of urban flooding to humans and environment. 3. to determine the solution in reducing flooding in urban area. 1.4 Research question(s) The main research questions of this study are: 1. What are the reasons of urban flooding? 2. What are the effects of urban flooding to humans and environment? 3. What are the solutions in reducing urban flooding? 1.5 Definition of terms 1. Urban - in, relating to, or characteristic of a town or city 2. Flood - an overflow of a large amount of water beyond its normal limits, especially over what is normally dry land 3. Drainage - the action or process of draining something 4. Sewer system - an underground conduit for carrying off drainage water and waste matter 15 CHAPTER II REVIEW OF RELATED LITERATURE 2.1 Introduction In this chapter, we will discuss about the details of urban flooding from some journals that we have read. We are concerned about the factors, effects and solutions of urban flooding. The research sources are based on the E-library from UMP website. 2.2 Literature review 2.2.1 Factors of urban flooding The failure of an urban drainage system is defined as whenever the water level in a given point exceeds a critical level within one rainfall event or rainstorm. According to Thorndahl and Willems (2008), overloaded or flooding at certain manholes in drainage system will cause the malfunction of urban drainage system. By using the first-order method (FORM) with more consider the parameters the basis of failure probability estimation to investigate the failure of sewerage. As a result, we know that the FORM is an alternative probability method that research for coalescent of high possibility factor of malfunction of urban drainage system which will cause urban flooding. In the paper of Gallegos, Schubert and Sanders (2009), a case of dam-break flooding in urban area is used as study reference and high-resolution of urban flooding from a dam failure play the main role. The result shows that stream flow accuracy is proportional to flood extent. However, heterogeneous resistance may cause by the buildings representative method, pollutants or decaying of engineered flood structure. The conclusion is the inaccuracy caused by human being towards the development of urbanization brings trouble to them. Based on the study Akin B. Oguntala and J.S Oguntiyinbo (1982), the number of rainy days in Ibadan has been decreased, while the total quantity of annual rainfall is slightly increasing. The uncontrolled deforestation of hill slope and encroachment of river flood plains have increased the runoff 15 rate into stream and finally bringing about flood. In a conclusion, improper of designing of urban drainage, building presentation and environmental management will cause the decreasing of the flow accuracy. Dam break and poor engineered structure may also cause flood. 2.2.2 Effects of urban flooding According to Vinet (2008), the effects of flooding can be separated according to humans and environmental factors. Flood victims always face a problem on cost to repair the damage infrastructure because they loss their property. Besides that, the destruction of the public infrastructures is also the implication of the flood. Phones networks problems also affected. Death, physical injury and heavy material losses also will affect the flood victims emotional. Similarly, Mirza (2002) found that damage of the flood to humans and environment causes negative effects to many parties. Mirza (2002) founds that flood problem damage to agriculture and infrastructure in Bangladesh. The damage to socio-economic activities is also significant. It is because a devastating affects on large segment of the population especially those who are poor. The research also found the relations between global warming and floods that occurred in Bangladesh. Global warming caused by the greenhouse effect and it will lead more serious flood in Bangladesh. In contrast, Banerjee (2007) found that the effect of flood has positive implication on agricultural wages in Bangladesh. In other words, floods affect the demand and supply conditions in agriculture labor market. Flood years have higher agricultural than no flood years in Bangladesh. Monsoon crop season also causes the wages high. Banterer detailed out the wage fluctuation in times of flood. He also found that higher current wages usually cause by the high wage in the past. In conclusion, all people in this world should be aware that urban flooding causes a lot of bad events to humans and environment. Therefore, all people must cooperate and make sure the management of flood in future will be more efficient to reduce the cost of damage in infrastructure. Although the agriculture wages increase during flood, people must concern about the implication of flood to public damage and 15 also people’s life. 2.2.3 Solutions for urban flooding Texier (2008) recommends that to overcome this unexpected disaster, the first objective is to control the hazards with structural measures. The second objective is to make the poor population more conscious of flood hazards and sanitation by awareness campaigns by government. The third goal is to remove people from the flooded illegal districts and to relocate them into social housing (flat). As a result, we know the government plays an important role to prevent flooding. Flooding is very hard to prevent because it is an unexpected disaster in the world. On the other hand, Swan (2006) explores the relationship between increased urbanization and subsequent capacity problems within drainage infrastructure that will caused flooding. Swan (2006), suggests reducing or resolving the flooding problems with ‘ quick fix ’ engineered solutions, retrofit options, and long-term ‘planning-based’ remedial measures. In conclusion, proper urban planning and related sufficient drainage provisions for different areas covered under a city or township can play a significant role in arresting the menace of urban flooding. Similarly, Smith (2009) reports that recognition of the dual drainage problem and design consideration of the drainage, research and development when construct the drainage and GIS tools (Geographic Information System) and to support urban dual drainage modeling. In summary, construct and maintain drainage in isolation without consideration of overall integrated drainage and sustainability resulting in flooding. We need to be elaborately planned while developing a city or an area with some strategies planning and research, so that there will no flooding or disaster that will make people to suffer. 15 2.3 Conclusion In conclusion, urban flooding is caused by many factors, like malfunction of urban drainage system, dam break, the improper management of environment and development of urbanization. There are many effects that caused by urban flooding. For example, death, physical injury, heavy material losses, flood victims emotional, and damage to agriculture and infrastructure are the effects of urban flooding. However, there are also some ways to solve the urban flooding. Control the hazards with structural measures, remove people from the flooded illegal districts, proper urban planning and design consideration of the drainage are the solutions for urban flooding. 15 CHAPTER III RESEARCH METHODOLOGY 3.1 Introduction To investigate the question under consideration, as a researcher, we have been chosen the students of University Malaysia Pahang as our subjects. There are amount of 30 students are selected as our targets to answer our questionnaire. They are going to provide their opinions and information to us for our research about urban flooding. We are randomly selected UMP students from different faculties, different races and gender. 3.2 Procedures Questionnaire is the method that we have chosen to collect data that we need. The questionnaire has been divided into four sections. In section A, we have the background of respondents, section B is about the causes of urban flooding, section C is about effects of urban flooding while section D is about the solutions of urban flooding. Then, we give it randomly to respondents to answer it. The opinions that provided for us will help to analysis our research. 3.3 Data collection Data is recorded in code book by using Microsoft Excel. After that, the data are representing in the form of pie chart and the percentage is calculated. 15 CHAPTER IV FINDINGS & DISCUSSION 4.1 Introduction In this chapter, after collecting the questionnaires from our respondents, we gathered all the data and inserted them in the coding book. Then, we need to analyze them that related to our research. Therefore, we present the data in form of pie chart and we provide the results and discussion based on the pie chart. Besides that, we also provide reasons and relate the results with literature review. Lastly, we summarize the results. 4.2 Analysis and discussion of data- findings Causes of Urban Flooding 0% Drainage syatem 20% 28% The weather Management of urbanization 7% Management of environment 11% 16% Dam break Pollution 18% Other Figure 1: Causes of urban flooding Figure 1 describes about the causes of urban flooding. There are total of seven causes or options like drainage system, weather, and management of urbanization, management of environment, dam break, pollution and others. More people think that drainage system causes the urban flooding which shows the highest percentage (28%). 20% of cause of urban flooding is pollution, 18% is the management of urbanization 15 and management of environment take 16%. Besides that, a few people think the weather (11%) and dam break (7%) cause flood in urban area. However, there is no people share their other comments due this title. So, the option named other hits the lowest percentage of the causes of urban flooding (0%). The finding is same with found by S. Thorndahl and P. Willems (2008). According to S. Thorndahl and P. Willems (2008), overloaded or flooding at certain manholes in drainage system will cause the malfunction of urban drainage system. On the other hand, the urban flooding due to dam breaking also has been stated in the paper of Gallegos, H.A., Schubert, J.E. and Sanders B.F. (2009). Based on the study on Akin B. Oguntala and J. S. Oguntoyinbo (1982) improper management of environment is one of the factors of urban flooding. Similarly, in the pie chart, this three causes are having the most supports (66%) which indirectly also support our research. In conclusion, there are more supports from people to the statement that drainage system causes urban flooding. 15 The Activities in Forest Contribute to Urban Flooding 0% 20% 10% Fire Camping Deforestation Buid dam 70% Figure 2: The activities in forest contribute to urban flooding Figure 2 describes about the activities in forest contribute to urban flooding. 70% of the people think that deforestation is the main activities that may cause urban flooding. As a result, deforestation hits the highest percentages. Besides that, 20% of people also support that build dam is the main activity in forest which contribute to urban flooding. Fire in forest has 10% of support among the respondents. There is no one think that camping is the main factor of urban flooding. Similarly, the study on Akin B. Oguntala and J. S. Oguntoyinbo (1982) stated that the improper management of environment especially uncontrolled deforestation of hill slope, blockage of natural drainage and encroachment of river flood plains have increased the runoff rate into stream and finally bringing about floods. The others activities like fire in forest, camping and build dam are not the main factor of urban flooding. In conclusion, deforestation is the main activity in forest which can contribute to urban flooding. From the chart, we will know the main factor due to urban flooding. 15 The effects of urban flooding Water damages to house or structure 25% 33% Water damage to contents (furniture, appliances, personal effect) Transportation disruption 17% 25% Lost income because of misses work or business closings Figure 3: The effects of urban flooding Figure 3 describes the effects of urban flooding. Overall, the effect is water damages to house and structure. More than one third/ (33%) agree that water damages to house or structure is the effect of urban flooding. Water damage to contents like furniture, appliances and personal effect and lost income because of misses work or business closings also the effects of urban flooding. About 25% of people agree for these two effects. Finally, the effect of urban flooding is transportation disruption (17%). The above result is similar to the findings by Vinet (2008). In his research, he found that industries, shops and private housing suffer during floods. Flood victims also had a problem about cost to repair the damage infrastructure. In conclusion, there are many effects of urban flooding but the water damages to house or structure is the main one. 15 The action that can be taken to reduce the effect of urban flooding 5% 17% Participate in any type of emergency flood fighting Moved to higher elevation 34% 44% Flood proofed or modified structure None of above Figure 4: The action that can be taken to reduce the effect of urban flooding Figure 4 describes the action that can be taken to reduce the effect of urban flooding. Overall, the action that people take to reduce the effect of urban flooding is moved to higher elevation. The first action to reduce the effect of urban flooding is moved to higher elevation. About 44% of people agree for this action. The second action is used flood proofed or modified structure that can prevent urban flooding. More than one third/ (34%) agree for this action. The other reasons for reduces the effect of urban flooding is participate in any type of emergency flood fighting (17%). Finally, 5% agree that none of these actions that they take to reduce the effect of urban flooding. The above result is similar to the findings by Texier (2008). In his research, he found that the solution of urban flooding is remove people from the flooded illegal districts and relocate them into social housing (flats). He also mentioned that controlling the hazards with structural measures. In conclusion, there are many actions to reduce the effect of urban flooding but moved to higher elevation is the main one. 15 The most effective solution to prevent flooding 10% Awareness campaign by government. 3% Proper design and repair for the drainage system in urban area. 33% 54% Plant more trees in the urban area. Remove the people from the flooded illegal districts. Figure 5: The most effective solution to prevent flooding in urban area Figure 5 shows the most effective solution to prevent flooding in urban area. According to the chart, proper design and repair for the drainage system in urban area has the highest percentage while awareness campaign by government has the lowest percentage. As illustrated by the chart, the most effective solution to prevent flooding is proper design and repair for the drainage system in urban area about 54%. Plant more trees in urban area is the second highest which is 33% for the most effective solution to prevent flooding. Remove people from the flooded illegal districts is about 10% and awareness campaign by government is about 3% only for the most effective solution to prevent flooding. The finding is similar to Swan, A. (2006). In his study, he explores the relationship between increased urbanisation and subsequent capacity problems within drainage infrastructure that will cause flooding. It is similar to current finding which is proper design and repair for the drainage system in urban area is the most effective solution to prevent flooding. 15 It can be conclude that proper design and repair for the drainage system is the most effective solution to prevent flooding because drainage system is a very important system by which the water level on or in the river is controlled so that flooding can prevent. 15 Drainage system play an important role in preventing flooding in urban area 3% Yes No 97% Figure 6: The drainage system plays an important role in preventing flooding in urban area Figure 6 shows the drainage system plays an important role in preventing flooding in urban area. According to the figure, about 97% respondents agree that drainage systems play an important role in preventing flooding in urban area. Only 30% respondents do not agree that drainage system play an important role in preventing flooding in urban area. Based on the study of Smith, M. B. (2009), he comments that recognition of the dual drainage problem and design considerations of the drainage, research and development when construct the drainage, and GIS tools (Geographic information system) and to support urban dual drainage modelling can prevent flooding. It can be conclude that drainage system is very important to prevent flooding with proper design and consideration to control the water flow while the water elevation is high. 15 CHAPTER V CONCLUSION AND RECOMMENDATIONS 5.1 Introduction This chapter contains summary of the findings. We provide the limitations of the study. Besides that, we also include suggestions for further study based on the research outcome in this chapter. Therefore, we can provide concluding remarks of our research. 5.2 Summary of findings Based on our results and analysis, there are more supports from people to the statement that drainage system causes urban flooding. Deforestation is the main activity in forest which can contribute to urban flooding. There are many effects of urban flooding but the water damages to house or structure is the main one. Therefore, there are many actions to reduce the effect of urban flooding but moved to higher elevation is the main one. Proper design and repair for the drainage system also are the most effective solution to prevent flooding because drainage system is a very important system by which the water level on or in the river is controlled so that flooding can prevent. Besides that, drainage system is very important to prevent flooding with proper design and consideration to control the water flow while the water elevation is high. Although we had some limitations during our research such as the content of the articles which related to our research objectives that we found were limited but we are still able to complete this research by applying another way to remediate the demerit or limitation of our research. 5.3 Limitation of the study The limitation of our research is the respondents. The knowledge about the urban flooding is limited because we choose students as the respondents. They do not have enough experience or knowledge about urban flooding. The second limitation of our research is the irresponsible respondents. We are hard to find responsible respondent. So, we also faced the problem to get back the questionnaires and some of the respondents is not answer the question seriously which is some question was blank. The third limitation about our research is the literature review. We were very hard to find an article or journal 15 which is relevant to our topic and objectives in limited time. 5.4 Recommendations for further study Based on the results that we get, we suggest that choosing a respondent is very important. We should choose the respondent which has enough knowledge and experience about the urban flooding, For example, drainage designer, civil engineering, and others. We also recommend that to choose the responsible respondent. It is means that the respondent should have responsibility to answer the entire question seriously and care the questionnaires. For the further research, we should try our best to find a suitable article that relevant to our research. We also suggest that co-operation and time management is very important to find a suitable article in limited time. For future, hopefully we are capable to overcome all the limitations and improve ourselves in doing research. 5.5 Conclusion remark In a nutshell, our research is about the flooding in urban area. The research objectives are to find out the factors, effects and solutions of urban flooding. While in questionnaire research, most of the opinions that we had collected are almost the same as the literature review that we did. The respondents are able to give their useful opinions due to our research. It means we are able to achieve the research objectives and the research questions which we had been mentioned in our report proposal. In conclusion, we hope that we are competent to come out with more useful and valuable research. 15 References Banerjee, L. (2007).
