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 one of the theory-based infiltration methods, Green-Ampt method is widely used in hydrologic modeling to account for loss from infiltration. Green-Ampt method was initially developed for ponded infiltration into…
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 which include canopy interception, surface depression storage or initial loss, and evapotranspiration…
The Deficit and Constant Loss Infiltration Method can be implemented in HEC-HMS, HEC-RAS (2D rain-on-grid), and InfoWorks to account for precipitation loss through infiltration and percolation. In order to facilitate…
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…
