Book Description
The Hydrological Simulation Program-FORTRAN (HSPF) is an analytical tool designed to simulate hydrology and water quality in natural and man-made systems. HSPF is used to apply mathematical models to simulate the movement of water, sediment, and other constituents through watersheds. This analysis helps predict possible environmental problems in the watershed. With the growing need to care for and monitor the effects of man on the environment, it became apparent that a method for rapid analysis of those effects was needed. The Watershed Modeling System (WMS) interface creates a way for the user to input a multitude of parameters into the input file and then to run HSPF. The input parameters are linked to all the tools within WMS including automated basin delineation and parameter definition using a graphical user interface. As mentioned above, the purpose of including an interface to HSPF in WMS is to provide a way for engineers to delineate a water-shed and set up an HSPF model quickly. The watershed delineation tools, as well as the Geological Information System tools, in WMS allow automated development of much of the input necessary for HSPF. However, several new tools and dialogs have been added to complete the HSPF input data. To begin an HSPF simulation in WMS, the HSPF data must be initialized for the watershed model. This is a simple procedure that involves the click of a button within the HSPF Global Options dialog box. Once the data are initialized, the user may access the various dialog boxes within the HSPF interface. The following sections will describe the input dialogs involved in the interface and will explain the expected input parameters. It is recommended that the user consult the HSPF documentation to receive a complete description of how HSPF uses the parameters.

Book Description
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.

Book Description
The Sandies and Elm Creeks were placed on EPA’s 303(d) list in 2000 due to depressed dissolved oxygen and elevated bacteria levels. Given the rural, agricultural nature of the watershed, a Total Mass Daily Load (TMDL) study was initiated to determine the source or sources of the non-point source pollution. A model needed to be developed that simulated the agricultural runoff from the watershed. The simulation model, Hydrologic Simulation Program – FORTRAN (HSPF) was chosen. A typical HSPF model was conceived, but during the course of the study circumstances forced the model to develop in an atypical way. The classic source of precipitation forcing data, the National Climatic Data Center, lacked point precipitation stations with data during the calibration timeframe; therefore alternate data sources were reviewed and NEXRAD data was chosen as the alternate data source. But, the use of NEXRAD data required that the model be distributed to a greater degree than a classic HSPF model. This delineation pushed the HSPF code to the edge of its design and encouraged examination of the weaknesses of both HSPF and hydrologic modeling in general.

Book Description
A watershed model using Hydrologic Simulation Pro- gram—FORTRAN (HSPF) was developed for the urbanized Chino Basin in southern California to simulate the transport of pathogen indicator bacteria, evaluate the flow-component and land-use contributions to bacteria contamination and water-quality degradation throughout the basin, and develop a better understanding of the potential effects of climate and land-use change on water quality. The calibration of the model for indicator bacteria was supported by historical data col- lected before this study and by samples collected by the U.S. Geological Survey from targeted land-use areas during storms in water-year 2004. The model was successfully calibrated for streamflow at 5 gage locations representing the Chino Creek and Mill Creek drainages. Although representing pathogens as dissolved constituents limits the model's ability to simulate the transport of pathogen indicator bacteria, the bacteria concen- trations measured over the period 1998-2004 were well rep- resented by the simulated concentrations for most locations. Hourly concentrations were more difficult to predict because of high variability in measured bacteria concentrations. In gen- eral, model simulations indicated that the residential and com- mercial land uses were the dominant sources for most of the pathogen indicator bacteria during low streamflows. However, simulations indicated that land used for intensive livestock (dairies and feedlots) and mixed agriculture contributed the most bacteria during storms.
