Direct Runoff depth given Sum of Ordinates evaluator uses Surface Runoff = 0.36*((Sum of Ordinates*Time Interval)/Catchment Area for Hydrograph Analysis) to evaluate the Surface Runoff, The Direct Runoff depth given Sum of Ordinates is defined as the value of direct runoff depth when we have prior information of other parameters used. Surface Runoff is denoted by Sr symbol.
