The impacts of radar-precipitation-estimation on streamflow simulation with HSPF

摘要

The HSPF model was used to simulate watershed hydrology of the Whippany River Basin (WRB) in northern New Jersey, USA. Different types of precipitation data were used as input to HSPF, including data from an individual raingauge, interpolation of gauge measurements, and NEXRAD Radar Precipitation Estimation (RPE). The PEST tool was used for the model parameter calibration. The simulated results indicate that type of the precipitation input significantly impacts the output of HSPF, with RPE particularly favourable.
