This post is to explain how to set up an HMR 52 storm in HEC-HMS by using HEC-MetVue PMS parameters and how to optimize it by setting a objective goal…
Probable maximum precipitation (PMP) is theoretically the greatest precipitation for a given duration that is physically possible over a given size storm area at a particular geographic location. Probable maximum…
In Python, everything is an object, such as int, float, string, list, tuple, dictionary,... When you assign a value to a variable, you basically create an object with a reference…

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…
Clark Unit Hydrograph transform method was originally proposed by C. O. Clark in 1945. Clark Unit Hydrograph embodies two basic features of a watershed (drainage basin) rainfall-runoff process (Figure 1):…
