Hydrologic simulation of storm water detention storage in an urbanizing flood-plan
Emerging concepts of urban flood control consider the use of storage detention, especially where channel capacities are being overtaxed by urban runoff. Particular problems exist where high rainfall intensities and low topographic relief combine with rapid urban development to produce potential …

Hydrologic and water quality modeling with HSPF : utilization of data from a novel field data collection system and historical archives
… motivate an investigation into the modem uses of hydrologic and water quality models. The Hydrologic Simulation Program - FORTRAN (HSPF) is applied using data from the Williams River basin, New South Wales, Australia. The Williams River is an agricultural catchment with interesting physical …

A systems approach to evaluate water quality oriented land management plans
A systems approach, utilizing a deterministic hydrologic simulation model and an optimization model, was developed to evaluate and optimize cropland Best Management Practices (BMPs). The approach consisted of using the Finite Element Storm Hydrograph Model (FESHM) to simulate runoff and sediment …

Toward improved evaluation of large scale hydrologic models: estimation and quantification of parameter uncertainty
With the development of increasingly complex hydrologic models that use a wide range of parameters to represent hydrologic processes both in space and time, many challenges arise with respect to simulation and quantification of uncertainty. The goal of this research is to introduce strategies to …

Near Real-time Seasonal Drought Forecasting and Retrospective Drought Analysis using Simulated Multi- layer Soil Moisture from Hydrological Models at Sub- Watershed Scales
… daily soil moisture dataset is obtained at Hydrologic Unit Code (HUC-12) resolution for a period of January 1982 through December 2013. A near real-time hydrologic simulation framework by coupling the calibrated SWAT models with the National Centers for Environmental Prediction (NCEP) …

Agent-based models of socio-hydrological systems for exploring the institutional dynamics of water resources conflict
… the substance of this theory using comparative, simulation-based analysis of water resources systems in the USA and Spain. I determine whether, given two artificial societies experiencing water conflict, expanding institutional capacity would indeed lead to reduced conflict levels. I develop and …

Modeling Hydrological Response to Potential Climate Change and Urbanization in the Kishwaukee River Basin
… Basin (KRB) in Illinois and Wisconsin, USA. The Hydrologic Simulation Program - FORTRAN (HSPF) was applied for the KRB after being calibration. The calibrated HSPF model was run first with urbanization scenarios generated by a dynamic urban growth model (LEAMluc) and hypothetical urbanization …

Understanding the role of scale in assessing sediment and nutrient loads from Coastal Plain watersheds delivered to the Chesapeake Bay
… to urban an agricultural land uses, and hydrologic connection of the Coastal Plain to receiving waters. To mitigate the impacts of urban and agricultural runoff, a variety of stormwater control measures (SCMs) are implemented. Despite the importance of the Coastal Plain on water quality …

SET-WET: A Wetland Simulation Model to Optimize NPS Pollution Control
… continuously stirred tank reactor, simulation model (SET-WET) was developed for design and evaluation of constructed wetlands in order to optimize non-point source (NPS) pollution control measures. The model simulates the hydrologic, nitrogen, carbon, dissolved oxygen, bacteria, …

Hydrologic calibration of the Cub Run Watershed using the PC version of the Hydrological Simulation Program - FORTRAN (HSPF)
The Hydrological Simulation Program - FORTRAN (HSPF) in its personal computer version, release 10.10, was used to perform the hydrological simulation of a sub-watershed of the Occoquan River drainage basin. The sub-watershed selected was the Cub Run Watershed located in the northern area of the …

Development and evaluation of a watershed-scale hybrid hydrologic model
<p>A watershed-scale hybrid hydrologic model (Distributed-Clark), which is a lumped conceptual and distributed feature model, was developed to predict spatially distributed short- and long-term rainfall runoff generation and routing using relatively simple methodologies and state-of-the-art spatial …

Procedure to Quantify Environmental Risk of Nutrient Loadings to Surface Waters
… quality is estimated using the stream module of Hydrologic Simulation Program FORTRAN (HSPF). The risk is calculated as the product of probability of occurrence of a NPS event and consequences of that event. The risk quantification procedure was applied to a watershed in Virginia. Total …
