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):…
Modified Puls Routing, also known as storage routing or level-pool routing, is a commonly used reach (channel) routing method in HEC-HMS. Modified Puls Routing is based on continuity equation. In…
The standard hydrologic grid (SHG) is a grid system developed by USACE Hydrologic Engineering Center (HEC) to cover the conterminous United States for hydrologic modeling purpose in HEC-HMS. SHG is…
A Horizontal datum is to measure a location on the Earth's surface in latitude and longitude or other coordinate systems. A vertical datum is used to measure the elevation or…
