Hydrological Modeling at Basin Scale with HEC HMS Tutorial

The Hydrologic Modeling System (HEC-HMS) is designed to simulate the complete hydrologic processes of dendritic watershed systems. The software includes many traditional hydrologic analysis procedures such as event infiltration, unit hydrographs, and hydrologic routing. HEC-HMS also includes procedures necessary for continuous simulation including evapo-transpiration, snowmelt, and soil moisture accounting.

This tutorial is about the hydrological modeling at basin scale using different hydrological process as:

• Evapotranspiration
• Baseflow
• Interception
• Surface accumulation

The tutorial uses the Soil Moisture Accounting method and compares the results with observed flow measurement on the basin.
