Dam and Reservoir emergency preparedness plan for Suoi Trau Reservoir – Ninh
Hoa – Khanh Hoa
Goal of Emergency Preparedness Plan (EPP)
This EPP is used as a guide to assist the local planners to response with over-discharge floods
or the broken-dam floods of SuoiTrau reservoir. The provincial government and downstream
cities should use EPP as a guide to develop additional information for their own Emergency
Response Plan (ERP) to directly handle flood issues or broken dam.
The EPP will summarize in detail the actions that Suoi Trau dam Manager, i.e Khanh Hoa
Irrigation Works Exploitation One-Member Company Limited, will take in an emergency
such as giving warnings to downstream authorities; announcing what the Khanh Hoa IMC
will do in the dam area to minimize the emergency situation; warning what will happen in
downstream of the dam, and how people and assets will be affected by flood; providing flood
maps to identify areas flooded; providing a list of people to contact and phone book; the best
things that downstream authorities have to do to respond to emergencies such as evacuation,
shelter, transportation; and how emergency responders will be notified of any emergency
situation involving major floods or potential or imminent dam failure. The EPP is an
integrated document that all agencies and authorities can refer to in an emergency.
In case of, there is an emergency at the Suoi Trau reservoir, provincial, city, the authorities
of provinces, cities, and other stakeholders in the downstream arear should be contacted via
the Flow Charts for Emergency Management and deploy as soon as possible.
This EPP includes the following information:
- The map of the degree of inundation, time the flood flows to downstream areas and the
estimated time of flooding;
- Things that responders have to do in an emergency.
- Mechanism and flow chart of dam safety notice;
- Telephone, fax, email contact of agencies and response officials
Research Scope
EPP of Suoi Trau reservoir focuses on studying the risks that can cause the main dam failure,
flood discharge with large flow of Suoi Trau when the basin has heavy rain, etc. The affected
area is quite large stretching from Suoi Trau dam, EaKrongrou dam, and Da Ban dam to Nha
Phu Bay with a total length of Suoi Trau 1.2km, Cai River 42.4km, and Lop River 19.2km
with the purpose of determining the boundary of water level for the mathematical model. In
which, the scope of implementation for the evacuation plan is from the downstream of Suoi
Trau reservoir in two streams: (1) From the spillway to the Dinh Ninh Hoa river basin with
a length of 1.2 km; (2) From the main dam to the river of Dinh Ninh Hoa river with a length
of 0.74km including Ninh Xuan commune, Ninh Hoa town.

Suoi Trau reservoir does not have a proper operating procedure for regulating the lake, or an
outdated operation process, not have annual operating procedures for water storage and flood
discharge compared to the actual flow to; The recording and keeping of data during operation
are incomplete.
Since there is no process to operate the reservoir, the managers often operate based on their
experience; leading to high dam safety risks. In the present condition, it is necessary to
develop and issue a process for operating Suoi Trau reservoir
b) Inspection and Assessment of Dams
Every year, the general manager of the dam conducts inspections and reports the current
safety status of the dam before the flood season.

1.6 The legal basis for making an EPP
- Construction Law No. 50/2014 / QH13;
- Decree No. 32/2015 / ND-CP dated March 25, 2015 of the Government on construction
investment cost management;
- Decree No. 46/2015 / ND-CP dated 12/5/2015 of the Government on quality management
and maintenance of construction works;
- Decree No. 114/2018 / ND-CP dated September 4, 2018 of the Prime Minister on safety
management of dams and reservoirs
- Contract No. 04/2019 / HDTV-WB8 dated July 22, 2019 between the Management Board
of Dam Rehabilitation and Safety Improvement Project (WB8) in Khanh Hoa province and
Thuy Loi University in Consultancy for emergency response planning (EPP), under the Dam
Repair and safety improvement (WB8) project in Khanh Hoa province.
CHAPTER 2 - RESPONSIBILITY IN IMPLEMENT EPP
2.1 Current responsibilities for dam safety management and EPP
The identification of responsibilities for EPP-related tasks needs to be done during the
development of the plan. Dam management is responsible for the construction,
maintenance and implementation of EPP's tasks, which is very important, so that
appropriate actions can be taken when an emergency occurs. Emergency management
officers at city, district and local levels have the duty and responsibility to notify and
evacuate affected areas downstream in an emergency.
At present, the safety management of Suoi Trau Lake dam in the case of normal operation
of the dam is under the responsibility of Khanh Hoa IMC. However, when emergency
conditions occur, the Suoi Trau reservoir ‘s Board of Flood and Storm Control
(hereinafter referred to as Suoi Trau’s Flood and Storm Control Board) coordinates the
downstream agencies and organizations by implementing ERP to flood-prone areas in
rescuing victims and mitigating the impact of floods. Suoi Trau’s Flood and Storm
Control Board is responsible for preparing the Annual Planning for Flood and Storm
Control and Disaster Mitigation with the approvement of the Khanh Hoa Provincial
People's Committee. The plan must specify the activities necessary to reduce potential
flood damage in downstream of dams and reservoirs. Suoi Trau’s Flood and Storm

CHAPTER III: DETECTION, EVALUATION OF EMERGENCY
SITUATION AND ALARM CLASSIFICATION
When dangerous conditions are detected, the Khanh Hoa IMC needs to assess the
severity and determine which appropriate actions need to be taken to eliminate such
dangerous conditions. Once the hazard conditions have been assessed, the Khanh Hoa
IMC with the Suoi Trau‘s Flood and Storm Control Committee need to decide on the
emergency level and then set an Alert Level for that emergency condition.
3.1. Identify an emergency situation
3.1.1. Large flood discharge case
In this case, there is no risk of dam failure, but flood is very large, the spillway has to be
fully discharged, or because of a the reason (such as earthquake, dam destroyed, ...) need
to quickly discharge to low down water level. There may be some emergency situations
as follows:
- Unusual large flood, main spillway (free and open spillway) is working, large discharge
can potentially cause large flood downstream;
- For some reasons (flood is very large or the gate is clogged with valve gates ...), water
level raises high, spillway works in urgent and causes big flood in downstream (in case
the reservoir has emergency overflow).
3.1.2. Case of a dam break
- Water level raising highly creates the risk of water overflow on the dam crest and finally
cause dam break (dams are very large or floods are clogged valve gates, ...)
- Concentration seepage (through the dam body, foundation, shoulders, over the gill
bearing, overflow, or through horizontal cracks, or the system of potential leakage
circuits in the dam body, etc.) causes subsidence, leading to the risk of dam failure.
- The upper or lower dam slopes are slipped (due to a number of reasons such as the
higher of water level, the saturation line high up, heavy rains persist at the dam causing
the soggy of dam, the water level recedes quickly due to earthquakes, or destruction)
resulting in deformed sections. At this time, there is the possibility of cracks, water
passing through by and causing erosion, or the surface of the dam to sag into the water
to overflow through the top. These two possibilities can lead to the risk of dam failure.
3.2. Assessment and Classification of Emergencies
3.2.1. Assessment of hazardous conditions
After hazardous conditions have been detected from the early detection test, from the
above information and data, the severity of the hazardous conditions should be assessed.
Assess the severity of hazardous conditions based on the classification of the alert levels
that have been set for the project. The officer who directly manages dam, using the
hazardous conditions identified during the detection phase, will evaluate the conditions
based on the Alarm Conditions. Once the IMC staff has assessed and determined the
conditions for the alarm levels, they are responsible for notifying Suoi Trau Flood and
Storm Control Committee to confirm before the Suoi Trau Flood and Storm Control
Board issues an alarm to agencies and teams officials and people downstream of the dam.
3.2.2 Emergency classification criteria
No.
Alarm Level
Emergency’ cases
1
Level 1 (precaution)
Scenario 1: when there is no danger of dam
failure, but flooding downstream may occur
2
Level 2 (Ready)
Scenario 2: when the dam starts to have
problems, the problems develop slowly
3
Level 3 (urgent action evacuation order)
Scenario 3: when the risk of dam failure is
growing. This situation occurs only when there
still has time for further analysis before the break.
The condition of the dam may be deteriorating
but it is assessed that it cannot be broke within a
few hours.
Notify stakeholders of the request to overcome
the dangerous situation of the dam ...
4
Level 4 (break dam or massive
flood discharge - issue
evacuation orders)
Situation 4: When the dam is about to break.
That's the situation when "time is out of date" when the dam is broken, broken or about to
break. This situation was declared when there
was no time for measures to repair or prevent
dam failure. The dam has either been in the
process of breaking or is expected to break for a
few hours, not few days. Possible dam failure
scenarios need to be analyzed. Emergency notice
is required in this situation.
CHAPTER IV: MECHANISMS AND NOTICE CHART
4.1. Notification mechanism
The preparedness plan for the downstream of Suoi Trau Lake including the list of
agencies will be notified when the potential flood situation is announced and will occur.
Individuals and agencies included in the notification mechanism are:

4.3. Emergency contacts
The President, Director or Leader holding the EPP will be responsible for preparing the
Emergency Contact Directory for their organization, agency or office. The President of
People’s Committee is responsible for collecting such contact information and
aggregating it into the Emergency Contact List of EPP holder. The emergency telephone
contact list of EPP for emergency response action is shown in Table 4.1.
4.4. Evacuation plan
Evacuation plan and implementation are the responsibility of provincial, city and local
authorities. In most cases, the President of the City People's Committee will be
responsible for the safety of the people living in the flooded area due to the dam failure
or large flood discharge. The dam manager, in most cases, the Khanh Hoa ‘s IMC in
coordination with the Suoi Trau ‘s Flood and Storm Control Board will be responsible
for announcing the alert levels. When Alarm of level 2: Ready; alarm of Level 3: For
urgent action, and Alarm of Level 4: dam failure or major flooding and evacuation.
Khanh Hoa ‘s IMC reports to the President of the provincial People's Committee, the
province will notify the President of the City People's Committee and the President of
the City will be responsible for notifying people downstream of the dam. In case of a
possible dam failure, if many people live right after the dam, Khanh Hoa IMC director
and staff will have to take emergency measures to notify these people.
People downstream and in flooded areas need to be aware of alerts level of 2, 3 and 4
and they should be noticed danger is coming by horn, or loudspeaker or other means. by
President of the City People's Committee notify Radio and television stations to transmit
emergency information that ‘may be evacuation’ (Level 2 alert), or ‘evacuation is
necessary’ (Level 3 alert), or ‘must evacuate’ (Level 4 alarm).
Evacuation plan involves many agencies, support services and people supporting the
evacuation because hundreds of people may be involved in the evacuation process. Some
agencies and services that directly or indirectly assist in the evacuation are:
• Fire Prevention and Fighting department
• Department of Police
• Army
• Building services
• Bus
• Boats
• Water supply company
• Medical services, doctors and nurses
When an evacuation order and emergency are declared, all agencies and services will be
called to help evacuate. The Vice president of the City People's Committee should carry
out the evacuation and prepare the flood map, point out the areas that will be flooded and
be ready to inform the evacuation route for all people in affected areas. Evacuation routes
should be notified to transport authorities in provinces and cities so cars, boats and
helicopters can provide relief in the position of evacuation and transport in the right
direction. Evacuation requires coordination in evacuation and requires drills in advance
to make evacuation effective and reduce the possibility of loss of human life.
Evacuation routes and roads must be close to minimize the danger of flooding.
Evacuation sites should be established at suitable high land areas in the affected areas
where there is fresh water and food. All efforts should be made in advance and the City
People's Committee should be prepared in advance for occuring alerts level of 2, 3, or 4.
4.5 List of people downstream affected by flood
When announcing alarm of levels 2, 3, and 4, evacuation actions should be prepared. In
order to implement evacuation actions, it is necessary to identify people and areas that
will be affected by downstream floods. This work will be done by evaluating the flood
maps developed for PMF flood or 1: 10,000 floods, and for dam failure analysis. After
evaluating the maps, it is necessary to survey of a number of people in the flooded area.
In investigation, all persons in the affected area, will be identified by name. With this
information, the list of people affected by downstream floods can be prepared and
maintained. This list should be updated annually to include current information of actual
people in the affected area.
The President of the City People's Committee should be responsible for preparing the list
as soon as the investigation is completed.
CHAPTER 5 - EVACUATION PLAN
5.1. Choice of evacuation planning scenario
5.1.1. Summary of flood mapping results
Scenario 1: Suoi Trau spillway works in response to flood P = 0.1% to lake, downstream
with rain at frequency of 0.1%;
Scenario 2: Suoi Trau Lake spillway works with extreme PMF floods to the reservoir,
downstream areas with PMF rain;
Scenario 3: The main dam of Suoi Trau Lake breaks in the case of 0.1% flood, the water
level is at normal level, the downstream has rainfall of 0.1%;
Scenario 4: The Suoi Trau ‘s main dam is broken in the case of PMF floods, the water
level at the top of the dam, the downstream area has PMF rain.
Detailed flood calculation results and flood maps are presented in Volume II. The
following is a list of only some hydraulic results and flood map for some scenarios.

The confluence of Dinh Ninh Hoa river
On the map of WL, the water level can be divided into the following sections: (i) from
the dam base to the flood trace 1 (VT1), Hmax ranges from 23.53m to 19.34m, (ii) from
the flood trace 1 (VT1) ) to the confluence of Dinh Ninh Hoa river, the Hmax ranges from
19.34m to 19.32m,
On the map of flood propagation, the transmission period can be divided into the
following sections: (i) from the dam base to the flood trace 1 (VT1), flood transmission
time ranges from 0h 00min to 0h 15min, (ii) from the flood trace (VT1) to the confluence
of Dinh Ninh Hoa river, flood transmission time ranges from 0h 15min to 0h 20min.
On the map of inundation areas, classified by each flood depth, the flooded area is
32.20 ha
5.1.2. Selecting the scenario of making evacuation plan
- For simplicity in operation, each downstream area should be selected only one scenario
to set up plan. Each evacuation plan prepared for a representative scenario can be called
an evacuation plan.
- Representative scenario is chosen based on flood mapping results. Each scenario
represents a group of scenarios with similar in flooding levels, flooding times and losses.
The results of flood mapping based on the above 4 scenarios show that the flooded areas
and inundated areas are relatively similar, only differing in depth of flooding. Therefore,
for simplicity in operation, the consultant chooses a scenario: The main dam is broken
with PMF flood discharge.

CHAPTER VI: EMERGENCY RESPONSE PLAN
6.1. Emergency response plan or activities available before an emergency occurs
6.1.1. Following situations
The Director of Khanh Hoa’s IMC (Ninh Hoa Representative Office) regularly needs to
maintain the number of staffs operating and managing to ensure if an emergency occurs,
tracking and testing will be enhanced. Supervising of data is important to determine risks
such as: settlement, permeability and raising of water level. Special monitoring of water
level of downstream is important because it is more sensitive to changes severe seepage
or dam flow that compared to the water level index in a reservoir. Changes of water level
of downstream will be an alarm indicator to the field condition monitor as well as set
emergency management levels for the requirements for preparation of contingency
emergency plans.
6.1.2. Reaction in low light conditions
Khanh Hoa’s IMC (Representative Office of Ninh Hoa) needs to have a preparation plan
of the electricity supply such as main electricity system, standby power system, backup
equipment (such as light pole system), and handheld lighting devices (to reach out to the
problem locations).
6.1.3. Approaching the site
Khanh Hoa ‘s IMC (Representative Office of Ninh Hoa) needs to base on the danger
signs as well as the alert levels to have a reasonable and timely plan to access the site.
There are two main roads that forces and materials can approach the main dam as arising
incidents.
6.1.4. Reaction during weekends or holidays
On weekends or public holidays, the operational and maintenance person of the dam and
related structures are significantly reduced, so the response are needed to mobilize
personnel in case of happened something. Special procedures need to be in place to
promptly contact and notify operating and maintenance personnel. Transport should be
ensured to pick up personnel for operation and maintenance, take them to the site in the
shortest time to deal with urgent situations and carry out timely repairs.
6.1.5. Reaction when the weather is unfavorable
In case of unfavorable weather, operation and maintenance personnel need to be fully
mobilized at the site to participate in monitoring, inspecting and monitoring dam work
and associated works. If an emergency occurs, operating personnel should be specifically
instructed in case of a sharp rise in the lake water. Emergency vehicles, equipment and
manpower should be mobilized in case of unfavorable weather.
6.1.6. Backup communication systems.
Backup transports must be specifically identified to use for emergency situations.
Telephone and mobile phone lines may not be used in case of adverse or very bad weather,
so the others of communication as shortwave radios on emergency vehicles that move to
Khanh Hoa ‘s IMC (Representative Office of Ninh Hoa) can be used. The
communication system from the dam or the spillway must be always ready to promptly
notify the center if there are some sign such as settlement, permeability and closing
conditions of the flood spillway gates with levels. Different water in the reservoir.
6.1.7. Information and equipment supply in case of emergency situations
