| Abstract: | The Hydrological Simulation Program in Fortran (HSPF) is used extensively for the assessment of water quantity and water quality issues. Herein, the development of an open-source, cross-platform package for building input files, performing simulations, postprocessing and calibrating HSPF models using the Python Programming Language is presented. The flexible nature of Python opens the door to automated preprocessing and calibration routines, visualization, multiprocessing, and larger-scale model development. The software is applied using Python scripts, which provides a flexible mechanism for learning and applying HSPF. An example application of the software was used to build a calibrated HSPF model the Hunting Creek watershed within the Patuxent River Basin, Maryland, USA, which is the example application distributed with the HSPF calibration software package HSPExp. A script of a few hundred lines was used to build a calibrated model comparable to HSPExp in a simulation time of less than two hours. |
