Determining Optimal Parameter Dimensions for Water Distribution Network Models
Water distribution systems contain a large number of pipes whose roughness factors are unknown prior to model calibration. During the calibration process, pipe roughnesses for each link...

A New Approach to Water Education: Children's Water Festivals
A number of Colorado water agencies, school districts, and municipal utilities have combined efforts recently to coordinate a relatively new concept in water education - Children's Water...

Regional Wastewater Reuse in the Nueces Estuary
The results of this study indicate that the firm yield lost to the release requirements of the Texas Water Commission Interim Release Order can be recovered by diverting treated wastewater...

Conservation Before and After: The Impacts of Increasing Block Rates on a Fully Metered System
Denver Water's inside residential consumption and revenues changed dramatically during a metering program and a conversion to inclining block rates. We analyze these two changes and make...

WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...

Using A Risk-Based Relative Position Analysis to Initiate Water Conservation Measures
When water utilities operate with annual demands close to safe yield, they must be prepared to invoke water conservation measures during droughts to assure adequate supply. Determining...

Analysis of Missouri River System Operations Alternatives
The Corps of Engineers is conducting a study of alternative water control plans for the exiting Missouri River Mainstem System. Data on the effects of the alternatives on the various project...

Parallel SDP for Multi-Reservoir Management
The use of stochastic dynamic programming (SDP) for solving water resources problems has been restricted to problems with low dimension due to the 'curse of dimensionality'. Algorithm...

Water Resources Development in the 1990's: A New Process
The development of water resources to meet future water needs has become more complex nowadays as regulatory agencies attempt to balance the proposed consumptive uses of water with a wide...

Wastewater Reclamation at Davenport, Washington
The City of Davenport, Washington went through an extended process to update their undersized wastewater treatment and irrigation reclamation systems for municipal wastewater. The process...

Managing the Russian River Aggregate Resources
As a result of analyzing the Russian River and its capacity to provide gravel, and through a sound examination of the geomorphology, hydrology, and groundwater conditions, the Sonoma County...

Reducing Discharges from San Francisco to the Bay
The City and County of San Francisco (City) is fairly unique in the west because it has a combined sanitary and storm water system. When the current Wastewater Master Plan (WWMP) was completed...

An Integrated Approach to the Real-Time Control of Water Supply and Distribution Systems
In recent years, real-time automated operation and control schemes have been implemented for a number of water supply and distribution systems with varying degrees of success. This paper...

Reliability Analysis of a Multi-Reservoir Water Distribution System
A methodology for evaluating system reliability is developed to assist in the planning and management of a multi-reservoir water distribution system. The minimum cut-set approach is employed...

Public Involvement and Participation: Planning Imperatives for the Coming Century
The literature has identified three types of responses to natural resources planning and management efforts in the United States. The first focused upon the more effective use of existing...

Opportunities, Constraints and Change in Reservoir Management
Changing hydrologic, economic, social and environmental conditions have focused attention on the opportunities for changing reservoir management. Such change can occur in three areas....

Survey of Stormwater Detention State of Practice
A survey of stormwater professionals in the United States and Canada was conducted by the Urban Drainage and Flood Control District in 1991 regarding the current state of practice in the...

A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...

Administering a Regulated Riparian System of Water Rights
Western states, facing steadily increasing demands on limited water resources, have developed administrative regimes for regulating water use based on the judicially developed private...

San Diego County Water Authority's Emergency Storage Project Supplying Water During Natural Disasters
The San Diego County Water Authority (Authority) is developing the Emergency Storage Project (ESP) to improve the dependability of the County's water supplies during a natural disaster...
