GIS-Integrated Surface Hydrology System
A GIS-based stormwater management system has been developed for the Pasco County Board of County Commissioners. The model draws all spacial data including watershed parameters, network...
Impact of Digital Elevation Model Grid Size on Extracted Drainage Parameters
The dependence of extracted drainage network properties on the spatial resolution of DEMs is investigated for a study basin. A series of raster DEMs of increasing cell size is generated...
Water Resources Management Using a Geographic Information System over a Wide Area Network
To assist in the management of water resources in the Santa Ana River Basin, in Southern California, the Bureau of Reclamation in Denver, Colorado and the Santa Ana Watershed Project Authority...
Simulation of Contaminant Migration Under Conditions of Declining Ground Water Levels
A ground water flow and transport model was developed to simulate the migration of contaminants originating from an industrial site. The development and calibration of the model were based...
National Weather Service Operational River Forecasting in a UNIX Environment
The mission of the National Weather Service (NWS) includes providing river and flood forecasts and warnings for protection of life and property, and providing basic hydrologic forecast...
Snow Estimation?A GIS Application for Water Resources Forecasting
In the Western United States approximately 75 percent of the annual runoff results from snowmelt. Observations of the snow cover provide an important source of information for forecasting...
A National System for Threshold Runoff Estimation
Threshold runoff is the amount of effective (or excess) rainfall of a given duration uniformly distributed over a certain catchment that is just enough to cause flooding at the outlet...
Storm Sewer Analysis & Design Utilizing Hydrographs
In this paper a computer model, designated STORM.HYD, for the analysis and design of storm sewer systems utilizing a hydrograph procedure is presented and discussed. This model which actually...
Next Generation HEC Catchment Modeling
The Hydrologic Engineering Center (HEC) is developing next generation computer models to replace those in current use. The next generation Hydrologic Modeling System (HEC-HMS) is an object...
Decision Support System for Water Supply Management
Water supply management is one area in which subjective decision making becomes necessary. Knowledge based decision support system is proposed for use in operation and management of an...
Prediction of Water Availability in River Headwaters and Control of Facility Water Demand in Response to River Flows
As part of the permitting and design of a power plant, the ability to supply cooling water subject to permit and availability constraints was investigated. As a first step, a synthetic...
Development of an Expert System for Urban Runoff
The U.S. EPA's Storm Water Management Model, SWMM, (Version 4.20, 1988) is a comprehensive water quality and quantity mathematical model for simulation of urban runoff in storm and combined...
A Sharp-Interface Salt Water Intrusion Code for Layered Aquifer Systems
This paper presents a quasi three dimensional, sharp-interface code that simulates salt water intrusion problems in layered aquifer systems. Efficient and robust numerical schemes make...
Verification Tests for Transport Modeling in Coastal Aquifers
The U.S. Geological Survey three dimensional Heat and Solute Transport (HST3D) model is used to simulate fate and transport of dissolved contaminant in coastal aquifers. The model originally...
