= = Physical Temperature of stream 11 degrees Celsius or 51.8 degrees Farenheit Air Temp. 13 degrees Celsius or 55.4 degrees Farenheit Stream width-5.7 m. You measure from wetted edge to wetted edge. Stream Depth: To be located on meters: 1.14, 2.28, 3.42, and 4.56 Point A: .225m, Point B: .225 m, Point C:.21m, Point D: .18m Substrate Constant= .8 rubble. Stream Velocity: Point A: 13.26 sec., Point B 5.97 sec., Point C: 5.98 sec., Point D: 7.30 sec. Stream volume=width x depth (m) x velocity x 8. Volume of flow=7.7m2 7,700 liters per second Average= 8.05 sec. 5/ 8 x .05=stream per second =.62 m per second = = =Stream mapping: measurements= Staring at point 9- Near 2.1/ Far 9.05 The near and far of the meter measurements show the point in which the stream started and ended to put in a stream map. =Stream map:= == = = = = = = The stream map was counted at intervals of 3 meters. The stream map shows us what the actual size of the stream was. In drawing it, you get a sense of if it is high or low gradient, how it sort of flows and what the environment has had on the impact of it. One example is the way the edges of the stream are can be because of erosion of the edge around the stream and that is why it is shaped the way it is. =Meaning of Data:= The stream water was 11 degrees Celsus and about 52 degrees Ferenheit. The coldwater species range is 21 degrees celsus and below and the temperature we got was 11 degrees, so that is very low. Trout, dace, sculpin, caddisflies, stoneflies, and mayflies live in these cold temperatures. Why was the stream so cold? Was it because of the long, cold winter we’ve had, or maybe because it’s been raining a lot lately. It could have even been that this water in the stream came out of a spring and spring water tends to be cooler. The air was cooler too, it was 13 degrees Celsus and about 56 degreed Ferenheit. Is this temperature normal around a stream or is it not? Could this be part of the reason the water was so cold? The air temperatures are okay for most living organisms around streams, however if the temperature went up the stream temperature would go up and more things would live in it. The width of the stream was just right for where is was located. Many organisms can live in a 5.7 meter width range, however at times the size of it could be dangerous. If a big rain storm came through it could easily erode the sides of the stream because of how skinny the stream is. The type of sediment beneath it can determine the depth of the stream. Under the stream was rubble and from point A-D the depth got big to small. This means as you got further away smaller critters would be at the shallow end and bigger ones at the deeper end. And the average depth is .21 and that means that mostly bigger critters live in this stream. The velocity of the stream from our data shows that at the ends of the baseline the water was moving the fastest and in the middle there was something built up and slowed down the velocity in the middle. So this also determined the depth of the stream and how it was deeper at the two ends and shallower at the middle. The volume of flow shows how much water is going through the stream at the baseline and at our stream there are 7,700 liters per second. So the stream can hold that much water at a time.
