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…
ModClark method is a distributed rainfall-runoff transform method available in HEC-HMS. To apply ModClark transform method, a basin (watershed) is subdivided into a gridded system and each grid cell is…
