A Geographic Information System to Support State-Wide Hydrologic Modeling with the SCS-TR-20
A geographic information system (GIS) that is structured for hydrologic analyses has been installed in the Maryland State Highway Administration's (MSHA) Division of Bridge...

Runoff Modeling Using the Geomorphological Instantaneous Unit Hydrograph and ARC/INFO Geographic Information System
The degree to which the spatial variability of watershed characteristics (geographical and climatological) is recognized for simulating watershed runoff depends on the hydrologic model...

Application of a Geographic Information System to Hydrologic Modeling Using HEC-1
A geographic information system (GIS) was used to derive areally-weighted hydrologic parameters for input to the HEC-1 hydrologic model for approximately 600 square miles of Pierce County,...

Automated Estimation of Hydrologic Parameters
An expert system was developed that automatically generates drainage area boundaries and times of concentration using digital elevation and stream data. Drainage areas and hydrographs...

A GIS Based Geomorphic Approach for the Digital Computation of Time-Area Curves
Hydrologists routinely operate simulation models to approximate the runoff process. A popular strategy is the routing of a 'time-area' histogram. In addition, state-of-the-art hydrologic...

Geographic Information Systems (GIS) and Remote Sensing?A Guide for Parameter Development in Water Resources and Environmental Modelling
Development in both software and hardware engineering in the last decade has resulted in the proliferation of GIS and remote sensing packages. While computer-based packages have experienced...

The Application of GIS Technology in Planning and Maintaining Distribution and Collection Systems
To date, the use of geographic information in the planning and maintenance of distribution and collection systems has been limited to AM/FM systems. However, the needs of engineers while...

Geographic Information Systems Technology for Environmental Infrastructure Networks
The recent developments in the Geographic Information Systems (GIS) industry have captured the attention of many professionals who regularly deal with the management of real-world geographic...

GIS Implementation on a Desktop Workstation
Geographic Information System (GIS) has now become an economically feasible reality. Technological progress allowed GIS capability at a very low cost. This progress greatly contributed...

A Perfect Base for a GIS: The Digital Orthophoto
A digital orthophoto is a rectified image with no relief displacement or radial distortion inherent in an aerial photo. One advantage of a digital orthophotography is that it can be used...

Regional Flood Control District GIS Applications
Clark County, Nevada is currently implementing a Geographic Information System (GIS) to support County planning and engineering functions. The Regional Flood Control District is in the...

Flood Plain Management Integrating GIS and HEC-2
Little has been done over the years to either automate the more labour intensive activities involved in flood plain management or to increase the efficiency and accuracy of handling applications...

Management of a Groundwater Basin Using an Integrated Numerical Model and a Geographic Information System
This paper describes the development and application of an integrated three-dimensional groundwater model and geographic information system (GIS) to the management of the San Fernando...

Management and Statistical Analysis of Groundwater Monitoring Data at Solid Waste Landfills
Solid waste landfills in Ohio and Michigan, as in many states, are required to have monitoring wells. Groundwater samples from these wells are analyzed to determine if leachate from the...

Current Status of Wetland Protection and Management in Tennessee
In order to save the remaining wetland resources and to manage these wetlands to the benefit of all, the State of Tennessee currently is in the process of formulating a comprehensive state...

An Intelligent Warning System for Real-time Operation of Water Systems
This paper describes the development of the Intelligent Warning System (IWS), a modular extension of the Operations Advisor and Simulated Intelligence System (OASIS). OASIS is a full-scale...

Application of GIS in Monitoring and Trouble Shooting of Water Distribution Systems
In this study, the suitability of Geographical Information System (GIS) to monitor water distribution systems is investigated. Although GIS applications are widespread, the use of GIS...

Rebuilding Buried Pipelines Without Digging
Advances and refinements in trenchless reconstruction technologies now permit system rebuilding of gravity and low pressure pipelines without excavation. Through the use of cured-in-place...

Water Distribution Infrastructure Analysis
Water distribution systems in many older cities of the United States need rehabilitation. Because the rehabilitation costs of the nation's water systems will involve billions...

The Use of GIS in the Study of Water Resources
GIS is becoming an increasingly important tool to the water resource plannar and manager. However, in order to integrate GIS effectively into this field, current and future hydrologists...
