Decision Support System for Water Supply Planning
A decision support system (DSS) has been developed to assist water use planners and technical staff of the Southwest Florida Water Management District in choosing appropriate supply alternatives...
Use of Models in Water Resource Systems: CRSS Experience
The Colorado River Simulation System (CRSS) is an in-house governmental computer-based model designed to be used as a decision support tool in performing long and mid range planning and...
Urban Hydrologic Modelling: HEC's Experience
Urban hydrologic modelling began at the Hydrologic Engineering Center (HEC) with the first versions of the HEC-1 Flood Hydrograph Package. The early applications were for large, primarily...
Hydrologic Modeling for Decision-Makers
All Properties within a community benefit from having an adequate system of storm drainage facilities and controls. Such benefits include: reduction of hazards to property and life resulting...
The Danby Pipe Renovation System
This paper describes a pipe renovation system and its structural characteristics which is cost effective and technically suitable in all sizes of pipe from 8 inches (200 mm) to the largest...
Reliability Consideration in Capital Improvement Programs
This paper shows an application of network reliability modeling in water supply capital improvement programs. The proposed approach consists of combining geometrical and structural properties...
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...
Los Angeles' Pipeline Rehabilitation Program
One-third of the City of Los Angeles' 7,000 mile water distribution system had been installed without internal protection. The Water System is aiming for a 900,000 foot per...
Adaptive Control of Groundwater Hydraulics
Adaptive control has been extensively applied in industrial settings for the control of unknowns systems, systems with uncertainty in the parameters. The approach is recursive, the response...
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...
Is GIS in Water Resources Better or Different
The Geographic Information System (GIS) is a relatively new tool which, when applied properly, may greatly benefit the water resources analyst. GIS technology combines sophisticated graphical...
Field Data-Gathering: Critical First Step for a GIS
Gathering data in the field is one of the first major tasks required for developing a geographic information system (GIS) or automated mapping/facilities management (AM/FM) system. This...
Using a GIS to Better Manage Water Resources in Texas
This paper examines five GIS applications under development in two state agencies in Texas responsible for the management and regulation of water resources, response to and remediation...
Stormwater/Wastewater Management: How an Application Can Drive a GIS
Decision makers are finding that a much-needed application may be the key that drives the creation of a city- or county-wide Geographic Information System (GIS). A start-up GIS developed...
Heuristic Optimization of Water Distribution Systems
A design heuristic for the optimization of water distribution systems is presented. Algorithm TREESEARCH finds a near optimal core tree layout. Algorithm REDUNDANCY adds redundant links...
An Alternate Formulation of Time as a Decision Variable to Facilitate Real-Time Operation of Water Supply Systems
With the advent of a new focus on energy conservation and the availability of cost efficient computer technology, many water utilities are investigating new ways to improve the efficiency...
Case Studies on the Use of Semi-Standalone Control Loops for the Management of Regional Public Water Supply
The West Coast Regional Water Supply Authority is charged with the operation and management of the public water supply that serves over 1 million people in the Tampa Bay Area of Florida....
A Control Method for On-Demand Operation of Open-Channel Flow
This paper proposes a control system for the automatic operation of an open channel having upstream and downstream gates. The main issue is the use of a discrete-time algorithm which computes,...
Network Modeling in a Water System with Ferrous Deposits
