AIM
The aim of this field investigation was: 1. To investigate stream channel characteristic to see how they vary downstream. * Does the stream get wider and deeper downstream? * Does a rock sample vary downstream? 2. Examine the different erosional and depositional features of the river. 3. To investigate the impact of humans downstream.

methodology
On this field trip we went to Wag Water River. We use material such as rulers, stop watch, sketches and description of sites was made; method of observation was used to see how humans use the river for various reasons. Along the river channel group of student did the following at different points;
Velocity: we measure the velocity of the river atleast three times to get an accurate measurement, we calculate the average. The velocity of the river was measured with a half filled bottle of water placed in the water at a given distance of 30m for some seconds (velocity=distance/time (seconds).The stream was also measured before and after tributary to show effect of tributaries, and deposit load which affects flow of the river stream and this was calculated by (cross section x velocity), then we compare the stream discharge at different sites and accounted for the differences.
After we did that we also measured the depth of the river, we used the meter rule for this measurement, for every meter we measured the depth then we find the average. Rock samples were also taken to classified as: very angular, angular, sub-angular, sub- rounded, rounded and well-rounded and measured with a meter. Hence fort the student identifies bed loading at the three different across the width of the channel (atleast fifteen for each stop).
WHEN: November 29, 2012
Where: We went to Golden spring, Toms River and Board gates.
