Lab 2

For our 2nd lab we went to the Ocmulgee River and did different experiments.  One of the experiments we did there was to measure the flow rate of the river at different depths.  We accomplished this by having a floating object and a stop watch to measure the distance traveled over time which gives a velocity.  Our results was that the deeper water had a slow but steady flow rate but the shallow water was literally stand still as our object barely moved forward at all.  Another experiment we did was to measure the amount of clams at different locations in the river.  We found out that in the deeper water the clams were more prominent compared to shallower water.  Along the shore also the clams were rarer than out in the deeper water.  The finals experiment we did  was to measure the difference in the elevation along the river bed.  We used two sticks with premarked lengths and a string attached between them to have a constant to go with the length.  This is the graph we created to show the difference between the width of the river and the depth.  The average depth of the trials was 19.8.
