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...

California's Orange County Water District A Model for Comprehensive Water Resources Management
The Orange County Water District in Southern California has developed over several decades a water resources management program that incorporates innovative control strategies, proven...

Compaq Center East Water Management Plan
This Water Management Plan attempts to balance the many goals which were established in the Master Plan. Major areas of natural vegetation have been preserved. Stormwater quality pond/wetland...

The Chesapeake Bay Critical Area Protection Program and the Baltimore Central Light Rail Line
This paper discusses Maryland's Critical Area Law, statewide guidelines and criteria, the Baltimore Central Light Rail Line, resource conservation areas, and other aspects...

Adaptive Parameter Estimation for Multisite Streamflow Forecasting
An adaptive procedure for parameter identification and noise statistics estimation for multisite streamflow forecasting is presented in this work. The model is a multivariate ARMAX model,...

Prediction of Runoff-Evapotranspiration to Estimate Leachate Generation in a Landfill
The fraction of precipitation that remains after runoff and surface water evaporation, enters into the solid waste landfill and generates leachate flow at the bottom. A part of the infiltration...

National Water Policy Issues and Activities
Active policy documents developed by the National Water Policy Committee of the American Society of Civil Engineeres or in cooperation with other policy committees and approved by the...

Guidelines for Water Resource Models Development and Use
Water resources literature suggests that computer based models have the potential to provide useful information in facilitating water resources decision making process. Therefore, continuous...

Use of Computers in the Management of Pecos River Compact
The Pecos River Compact between New Mexico and Texas did not define clearly what New Mexico's delivery obligation was. After a 14-year long litigation in the U.S. Supreme...

Using Off the Shelf Engineering & Business Software for Managing Water Resources, Case Study: Rancho California Water District (RCWD)
The paper presents the use of common engineering and business software packages for the purpose of managing water resources. A case example is presented where an existing water district's...

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...

Geostatistics in Groundwater Sampling Design
The geostatistical methods of kriging and co-kriging are compared as tools for the design of an optimal groundwater monitoring network. First, the network is optimized using single-variable...
