Effects of stream locationa. Gradienti. As you go down stream, gradient decresases overall from steep to gradualii. Steepness of slope is found: Rise/Runb. Dischargei. How much water flows ii. As you go down stream, discharge increasesiii. Calculated: Volume vs time1. Volume= X x Y x Z2. Ft cubed/secc. Channel Roughnessi. As you go down stream it goes from rough with a lot of uneroded material to smoother because of smoother sediments (decreases as you go down stream)d. Sizei. As you go down stream, size increases. Tributaries add water and erode more material These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Change As you move down streamGradient decreases overall from steep to gradualdischarge Increases as you go downChannel roughness Decreases.
