EMC Washoff Results

Figure 2.7 and Figure 2.8 show the runoff TSS concentrations simulated at different subcatchments both for the 0.1 in and the 0.19 in. (Figure 2.9) show the results for the 2yr storm. The concentrations are constant and correspond to the summation of the constant concentration in the rain (10 mg/L) and the EMCs assigned to the land uses within each subcatchment. Once the surface runoff ceases, the TSS concentration goes to zero. That is why, eventually, concentration for all the subcatchments reached zero after a certain time periods for individual subcatchments as they generate no runoff. Note that with EMC washoff, the size of the storm has no effect on a subcatchment’s runoff concentration.
