Stream Mapping Images with captions =Stream mapping procedure=

To map the stream, we began with measuring tape and a pink string, with clothespins. We measured down the stream 33m, with the pink string alongside of the measuring tape. These 33m symbolized the baseline on our graph we created. A clothespin was put every 3m. This was to show were we would take the measuring tape, and measure across the stream. The 33m string was perpendicular to the string we put across the stream to measure the width to graph. A compass was used to find North and put it on our baseline (the string). The string was headed 310 Northwest. This is because North is 360, and West is 270, therefore, the string was northwest. Measurements of each clothespin were as following:

=Temperatures= The stream temperature was 7 degrees Celsius. The air temperature was 11 degrees Celsius.

=Width= The stream width was 4.7 meters. We positioned 5 people in the water. One person was placed on one side of the stream and she held the meter tape. Then they stretched it to the other side of the stream. They measured the length from one of the sides where the water touches the land to the other. Then, they measured from the straight line (the pink string) to the edge where the water, meets the land. That’s how they found the different widths.

=Depth= We had 5 of our group members get in the water with meter sticks to measure the depth and 2 stood at the point 0 meters and 2 were standing at 3 meters. While that last group member was standing in the middle looking at a line leveler we had hanging on a piece of sting connecting the two meter sticks, and once it said that the string was level we took the meter sticks out of the water and divided the two different numbers to figure out what the depth was.

To find the stream depth, there was a string put across the stream with 4 clothespins spread across it evenly. There were meter sticks put to the bottom of the stream at each point of each clothespin. The measurements were as following: To find the average stream depth, we added all of the point measurements, and divided by 4.

=Velocity= To find the stream velocity, we used a tennis ball, and dropped it into the stream at each of the clothespin points on the string (the same points to find depth). We then measured down the stream 10 meters. We timed how long it took for the tennis ball to reach the 10 meter mark with the flow of the stream. We timed each process with a stopwatch, which was 4 times. The results were as following: Then, to find the velocity, we took 10 meters over the average time, which was 25.38 seconds. Our result was .394 meters/second. Therefore, the stream velocity was .394 m/sec.

Volume of Flow To find the volume of flow, the formula is wdvc. This means to multiply the width, the depth, the velocity, and the constant.
