Hspf calibration

WebThe Long Term Hydrologic Impact Assessment (L-THIA) model was previously improved by incorporating direct runoff lag time and baseflow. However, the improved model, called the L-THIA asymptotic curve number (ACN) model cannot simulate pollutant loads from a watershed or instream water quality. In this study, a module for calculating pollutant … WebHSPF model with the SCE-UA algorithm in a parallel computing framework supported by R (HSPF-SCE) with the purpose of providing an alternative and efficient tool for automated parameter calibration of HSPF. The new tool/approach was used to calibrate the HSPF models developed for three watersheds in Virginia.
