Lab 4 November 29, 2011-11-29 ABE 224 Jialing Ye Runoff Measurement and Erosion Evaluation Objectives Measure runoff from bare soil and soil with erosion control blanket (ECB), and investigate soil loss and the effects of ECBs on soil erosion. Materials and Methods, We measure the runoff from bare soil and soil with erosion control blanket (ECB) at the same time. We control the slope to be 5%, and we adjust the rainfall duration is 10 min and the intensity too. We put a bottle at the end of the soil cart to weight how much soil erosion after rainfall. After 10 min rainfall duration, we take the sediment sample from the bottle and place it in the oven to dry it. After we dry the run off we could find out the mass of sediment, and we can estimate how much soil loss from the total area by calculation. Results: The detail calculation is on another paper.
