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…
InfoWorks ICM is a powerful hydrologic and hydraulic modeling tool. As its name suggests, ICM - Integrated Catchment Modelling, InfoWorks ICM is capable of simulating 1D network and 2D surface…
As a theory-based infiltration method, Geen-Ampt is widely used in hydrologic modeling since its parameters are easy to acquire, especially for those project sites without monitored data for model calibration.…
In HEC-RAS 2D Rain-on-Grid (ROG) modeling, three layers are needed to model the infiltration loss and the procedures to create the three layers have been discussed before. Land Cover Layer…
In addition to loss through infiltration, during a precipitation-runoff process other losses may need to be accounted for as well, which include canopy interception, surface depression storage, and evapotranspiration (ET).…
Initial and Constant Loss Method and Deficit and Constant Loss Method are two common infiltration methods in HEC-HMS and they share the same underlying concept, simply put, after the "initial…
To model infiltration loss within 2D domain for a Rain-on-Grid (RoG) HEC-RAS model, a land cover layer and a soils layer needs to be generated first and then an infiltration…
