Unit hydrograph transform method for precipitation-runoff process is widely used by many H&H modeling tools, but EPA SWMM has its own method known as nonlinear reservoir runoff method which treats…
Time of Concentration (TOC or Tc), one of the most important hydrologic parameters for runoff calculation and modeling, is defined as the time it takes a drop of rainfall to…
For small drainage areas, the rational method is widely used to calculate peak flows of different drainage design levels to size storm sewer, inlets, culverts, and ditches. The rational method…
It is often required to evaluate the performance of a storm sewer system using multiple design storm events. Instead of running the same XPSWMM models using different single design storms…
