Once an acceptable trapping efficiency is determined, a calculation for overtopping must be performed. The overtopping calculation must be performed using the slurry flow rate through the fence. WebMar 16, 2007 · The simulated ponding time t psim, representing the “exact” solution, can be determined from the intersection between f sim (F sim) and r(R) (Figure 4, top) and the t(R) curve (Figure 4, bottom). It can be seen that the accuracy of the suggested direct method is good, even when ponding occurred during the steep increase of rainfall intensity.
