This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2002 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1982 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the development of the Hydrologic Simulation Program-FORTRAN (HSPF), a comprehensive simulation model for predicting watershed hydrology, water quality, agricultural chemical migration, and risk assessment. The model uses such information as the time history of rainfall, temperature, and solar intensity, and characteristics of the land surface, such as land use patterns, soil characteristics, and agricultural practices, to simulate the processes that occur in a watershed. The flow rate, sediment load, and nutrient and pesticide concentrations are predicted. The model takes these results and information about the stream channels in the watershed and simulates the processes that occur in these streams. This part of the simulation produces a time history of water quantity, quality, and chemical transport at any point in a watershed--the inflow to a lake, for example. For ease of presentation and interpretation, flexible routines are provided for statistical analysis of the simulation output. A risk assessment methodology to evaluate lethal and sublethal effects, using the median lethal concentration (LC50) and maximum acceptable toxicant concentration (MATC) as the key effects parameters, is part of the analysis.

Available in PDF, EPUB and Kindle. Book excerpt: A hydrologic model of the Spring Creek watershed was developed using Hydrologic Simulation Program Fortran (HSPF). The objective of the modeling effort was to develop a high resolution hydrologic model capable of modeling water quality. The goal of the model was to represent contaminant loading on a smaller scale than previous modeling efforts in order to identify the most effective areas for implementation of Best Management Practices (BMP) and the most effective types of BMPs to employ.
Download or read book Simulation Modeling for Watershed Management written by James Westervelt and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: A discussion of the role of modeling in the management process, with an overview of state-of-the-art modeling applications. The first chapters provide a background on the benefits and costs of modeling and on the ecological basis of models, using historical applications as examples, while the second section describes the latest models from a wide selection of environmental disciplines. Since management frequently requires the integration of knowledge from many different areas, both single discipline and multidiscipline models are discussed in detail, and the author emphasizes the importance of understanding the issues and alternatives in choosing, applying, and evaluating models. Land and watershed managers as well as students of forestry, park management, regional planing and agriculture will find this a thorough and practical introduction to all aspects of modeling.

Available in PDF, EPUB and Kindle. Book excerpt: This technical note presents the results of the incorporation of the Hydrologic Simulation Program-Fortran (HSPF) AOCHEM modules into the Watershed Modeling System (WMS). HSPF allows simulation of processes that affect water quality. Often the most significant of these processes are agriculture and chemical processes that take place on agricultural land segments. Such processes include application of pesticides and fertilizers. Included in HSPF are three modules that collectively are referred to as the AGCHEM modules: the PEST (pesticides) module, the NITR (nitrogen) module, and the PHOS (phosphorus) module. The AGCHEM modules allow users to model the processes that take place as part of agricultural practices.

This book was released on 2014-08-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "The Hydrological Simulation Program -- FORTRAN is a mathematical model that simulates hydrology and water quality in natural and man-made water systems. This report describes the work involved in maintaining and testing HSPF over a one-year period following its initial development. An account is given of the chronology of major events during the maintenance work. The testing included work with hypothetical data and checks against outputs produced by three predecessor models, the ARM, NPS, and HSP-QUALITY models. Through this process it was determined that the HSPF model functioned as designed."--Abstract.

This book was released on 2018 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conservation practices are frequently used to try and restore the natural resilience of the landscape to retain water, decrease nutrient loads, and mitigate flooding. Quantifying the potential benefits of conservation practices can inform stakeholders and improve the effectiveness of watershed planning. To this end, an existing Hydrological Simulation Program --- FORTRAN (HSPF) model of the English River was enhanced to enable detailed modeling of conservation practices. Using site-specific nutrient removal wetlands and water and sediment control basins (WASCOBs) derived from the Agricultural Conservation Planning Framework (ACPF) two 12-digit hydrologic unit code (HUC-12) watersheds within the English River, Headwaters North English River and Gritter Creek, were selected for modeling. Wetlands drain much larger areas than ponds that currently exist in the two watersheds. Average flood peak reductions are over 50% near the wetland sites, and diminish moving downstream to a few percent or less at the watershed outlets. Many WASCOBs exist in the two watersheds, but WASCOB use is minimal in other areas of the state. WASCOBs provide slightly more flood storage than ACPF wetlands but the storage isy distributed throughout the watershed. As a result the simulations show that the peak reduction is greater than for wetlands at many locations.
