Use of Remote Sensing and G.I.S. in the Economic Analysis of Flood Damage Reduction?Three Recent Case Histories
Three recent studies of the Trinity River in the nine-city Dallas-Fort Worth metroplex have been based on a regional geographic information system (G.I.S.), using digitized satellite imagery...

Applying a Simple GIS to PMP Analysis in a Microcomputer Environment
The analysis of probable maximum floods (PMF) in the Northwestern United States requires the inclusion of a snowmelt component combined with probable maximum precipitation. Traditionally...

Land Use Considerations and the Siting of Water Facilities
Land uses are an important consideration of water districts in the process of facilities siting. The methodology used to evaluate land use sensitivities in a large pipeline alignment study...

Real-Time Optimized Control of a Water Distribution System
The paper presents the design of a fully automated real-time computer control scheme for least cost operation of a water distribution system. The scheme includes modules for optimized...

Telemetry Data Considerations in Water Systems Control
The installation of increasingly sophisticated telemetry systems for data collection within the water supply and distribution networks has progressed rapidly in recent years. This has...

Meta-Site: Water Distribution System Analysis Software
Many local municipalities now require a network analysis for all proposed additions to their water distribution systems. A graphically oriented, user-friendly program is being developed...

Planning the Developmemt of the OASIS Advisory System
This paper describes the evolution of the Operations Advisory and Simulated Intelligence System (OASIS). In its first phase, already concluded, a prototype was developed for testing the...

An Expert System for Control Curve Evaluation During Drought
This paper presents ongoing research into the automation of control curve generation and the development of an expert system for reservoir management for North West Water of Warrington,...

Closing the Gap Between Water Resources Systems Education and Practice
This paper is focused on teaching system analysis and its water resources applications to engineers and architects. The content of courses generally offered under this title or similar...

Beyond Basic Modeling
Computers have long been used in water engineering to model hydraulic distribution networks In recent years, computer technology has exploded, yielding computers that are powerful and...

Optimizing Dallas' Multiple Reservoir Supply System
Dallas Water Utilities (DWU) applies a mathematical computer model of its reservoir supply system to assist in making operational decisions to optimize supply operations. The model considers...

Microcomputer Tools for the Management of a Multiple Reservoir Water Supply System
In a Raw Water Management Plan study performed for the City of Newport News Waterworks, Camp Dresser & McKee developed a series of micro-computer programs that allow the City to...

Storage Reallocation Evaluation for Reservoir System
Reservoir storage capacity is allocated to various purposes prior to project construction. However, changing needs and conditions may warrant later conversion of storage capacity from...

Economic Benefits of a Flood Warning System?The Ventura County, California Experience
Since the spring of 1979, Ventura County has been receiving the benefits of a growing Flood Warning System (FWS). Beginning with six self-reporting raingages, two untested flow models,...

The Dallas Floodway?Past and Present Successes in Flood Protection Benefits
This paper explores the history of the Dallas Floodway, past performance of the project under various flood conditions and, most recently, the present successes in flood protection provided...

Water Reuse in Las Colinas, Irving, Texas
The largest urban water reclamation project in Texas that involves reuse of treated wastewater was implemented in July 1987, to provide an economical and drought-free supply of water to...

Contributions of Satellite Imagery to Water Resource Evaluations
Satellite images may also facilitate the development and maintenance of regional Geographic Information Systems (GIS) by providing both a source of base map creation and update, as well...

Fuzzy Sets in Civil Engineering?A Tutorial
This tutorial is an introduction to the theory of fuzzy sets and its applications in Civil Engineering, including its use within the framework of knowledge-based systems. The techniques...

Tutorial: Fuzzy Set Theory in Water Resources Systems
Principles of using fuzzy set theory (FST) to describe imprecision (or vagueness) in water resources systems are provided. The main tool of FST, the membership function, measures the degree...

Bayesian Decision Theory and Fuzzy Sets Theory in Systems Operation
Operation of Water Resources Systems involves complex set of human decision. Many of the parameters involved in systems operations are random functions of time. Sometimes, the data needed...
