PRMS - Precipitation-Runoff Modeling System (Version 2.1,


PRMS - Precipitation-Runoff Modeling System (Version 2.1, 1/96)

DEVELOPED BY: US Geological Survey

PRMS system evaluates the impacts of various combinations of precipitation, climate, and land use on streamflow, sediment yields, and general basin hydrology. Basin response to normal and extreme rainfall and snowmelt can be simulated to evaluate changes in water-balance relationships, flow regimes, flood peaks and volumes, soil-water relationships, sediment yields, and ground-water recharge. Parameter-optimization and sensitivity analysis capabilities are provided to fit selected model parameters and evaluate their individual and joint effects on model output. The modular design provides a flexible framework for continued model-system enhancement and hydrologic-modeling research and development.
