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...

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...

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,...

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...

Corps of Engineers Water Control Data Systems for the 90's
Corps of Engineers water control data systems encompass all of the instruments, equipment, computers, and software used to collect and use environmental data in real-time water control...

A Prototype Distributed Processing System Water Control Data Processing at Tulsa District U.S. Army Corps of Engineers
The Tulsa District, Corps of Engineers operates 50 multi-purpose reservoirs controlling runoff from all or parts of 7 states. These reservoirs are operated for flood control, water supply,...

Recent Studies on the Optimal Operation of Reservoir Systems in China
Many researchers and engineers have examined the problem of optimal operation of hydro-electric systems in order to exploit the potential of electric power generation. At the same time,...

Unique Water Quality Aspects of Lake Pontchartrain
Natural factors causing changes in Lake Pontchartrain, can be grouped into the following: subsidence and wetland loss due to the deterioration of the St. Bernard Delta, natural variations...

Estimating Power Plant Cooling Water Demand
The Fayette Power Project (FPP) includes three generation units, with more than 1,500 megawatts of generating capacity, supplying electricity to more than a million Central Texans. The...

Stochastic Optimization for Long Term Operation of Multiple Reservoirs: A New Approach
The study emphasis of optimal scheduling of reservoir system operations has shifted to stochastic mathematical programming since future reservoir inflows are uncertain and recent advances...

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...
