Integration of the Hydrologic Simulation Program--FORTRAN (HSPF) watershed Water Quality Model into the Watershed Modeling System (WMS)

摘要

The integration of the watershed water quality model Hydrologic Simulation Program-FORTRAN (HSPF) into the Watershed Modeling System (WMS) was initiated as part of an overall goal of the Water Quality Research Program to provide water quality capabilities within the framework of a comprehensive graphical modeling environment for conducting hydrologic and water quality analysis. The WMS interface creates a way for the user to input a multitude of parameters into the input file and then to run HSPF to get the required output. The input parameters are linked to all the tools within WMS, including automated basin delineation and parameter definition using a graphical user interface. The objective of the interface developed in WMS is to provide graphical representation of HSPF data, as well as automate the definition of many of the required parameters. Many of the basic variables required for HSPF input are computed as part of WMS's basic functionality; additionally, specialty functions have been added to WMS to enable the usage of HSPF directly with data output from WMS. This report describes the initial linkage of HSPF into the WMS.
