HEC-HMS (Hydrologic Engineering Center - Hydrological Modeling System)

HEC-HMS (Hydrologic Engineering Center - Hydrological Modeling System) is a computer program used by engineers and scientists to simulate and analyze how precipitation and runoff flow through a watershed or catchment area. It helps predict water flow during storms, floods, or droughts by modeling processes like rainfall, infiltration, and streamflow. This tool supports water resource planning, flood risk assessment, and management decisions by providing detailed insights into how water moves across landscapes under various conditions. In essence, it transforms complex hydrological data into useful forecasts to aid in effective water management.
