This should be set out in the following format using these headings: Purpose of the experiment Equipment used How did you collect your data? Were you able to collect data successfully? Were there any difficulties? If so, how could you have done things differently? Step-by-step description of the river study process. Include failed attempts to collect the data 4) Self Evaluation TO BE HANDED IN □ General Observation Sheet □ Data collection Sheet □ Cross section □ Experiment Write up □ Self Evaluation Sheet River Study Record Sheet Lower Sackville River Study EQUIPMENT REQUIRED FOR EACH GROUP General observations and data recording sheets Tape measure Pencils Metre stick Thermometer Float (cork) Stop watches Rulers A) MEASUREMENTS – to be recorded on Data Recording Sheet 1. CHANNEL WIDTH 1) Hold or stake the tape measure at one Equipment bank Tape measure People required 2 + 1 recording 2) Stretch the tape measure tight across the river channel to the other bank, just above the water level. 3) Record the width Tape measure River bank 4) Leave the tape in place for the next river River bank measurement 2. CHANNEL DEPTH 1) At the first bank put a metre stick into Equipment the water until it touches bottom Tape measure 2) Read and record the depth from the Metre stick People required 1 + 1 recording bottom to the surface of the water 3) Repeat at 50cm intervals across the river, starting at the bank 4) Record the information in the chart Tape Metre rule River bed 3. BANKFULL WIDTH – the maximum volume of water the river channel can hold 1) Have one person place metre sticks at String pole Equipment the clear break in slopes on one side of Tape measure the river and one person place a metre 2 Metre sticks stick at the clear break in slope on the River Tape Measure River other side People required 3 + 1 recording 2) Run the measuring tape between the two sticks at the bottom. 3) Measure distance using tape River Study Record Sheet bank river bank Lower Sackville River Study 4. PEBBLE SCORE – this will give an indication of how efficient the river is and what processes are occurring (e.g. transportation, erosion, deposition) 1) Do this whilst others in the group are Tape Equipment recording depth Pebble board People required 1 + 1 recording 2) Take a sample of 4 stones from the river bottom at various locations across the river 3) Make sure that you pick four at random 4) Measure the pebbles in mm and record results 5) Describe the roundness type of each 6) Replace all rocks back into the riverbed. Select 4 stones at different location across the river River bed 5. Temperature Hold the thermometer in the center of the river for 3min. 6. Velocity Equipment Stop watch Measuring tape cork People required 1 + 1 recording 1) Do this at 5 different places across the river. 2) Have one person stand up stream, another one stand down stream 2 metres, and a third one on the bank with the stopwatch. 3) Release the cork and see how long it takes for the cork to float to the person down stream. 4) Record the results in the table River Study Record Sheet Tape Flow meter – propeller up stream River bed Lower Sackville River Study Self Evaluation This river study project required you to participate in group work, as well as work independently. Give yourself a mark out of 4 for each of the statements. Circle the appropriate number after each statement. During group and independent work, I stayed on task. I participated in the data collection process (Ex. took measurements, recorded data, took temperature, etc.) I did my share of the work. I was a supportive group member and listened to others ideas and opinions. I completed all independent tasks (site sketch, write up, self evaluation) Comments: River Study Record Sheet 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4
