Watercourse Master Plans: Two Case Studies
(No paper) The State of Arizona recently established statutes (ARS 48-3609.01) that enable local flood control districts to identify sensitive watercourses for floodplain management. The...
A Statewide Economic Optimization Model for California II: Model and Results
(No paper) Traditionally simulation models have been used for multi-reservoir operation studies. More recently deterministic optimization models have been used to identify promising alternatives...
City of Phoenix Water System Water Plan: Beyond the Year 2000
(No paper) System demands with the City of Phoenix water system are accommodated by utilization of water supplied from several different sources distributed through an interconnected system....
Del Webb's Innovative Approach to Master-Planned Community Development
(No paper) The Del Webb Corporation is currently building a master planned development on the northern edge of Maricopa County. The development plan includes a water campus housing a water...
Retrofitting CSO Infrastructure in New Haven, Connecticut
(No paper) The City of New Haven Water Pollution Control Authority operates a wastewater collection and treatment system which serves over 130,000 residents in the cities of New Haven,...
Economic Valuation of Agricultural Water Use for Large-Scale Modeling
(No paper) A state-wide irrigated agricultural production model has been developed for California. The model is an extension of the Central Valley Production (CVP) Model that was most...
Use of Economic Optimization to Evaluate New Facilities
(No paper) The confluence of the Sacramento and San Joaquin rivers and the San Francisco Bay forms the largest estuary on the West Coast. Known as the Bay-Delta, the region supplies drinking...
Use of Economic Optimization to Assess the Value of Water Marketing
(No paper) There is an increasing interest and implementation of water markets as an allocation mechanism for water in the Western U.S. However, the importance of the timing and location...
Roughness Coefficients in Manning's Equation as an Estimating Tool for Bankfull Discharge in Natural Channels
(No paper) This paper compares the results of Annable's work to the roughness coefficients by stream type given in Rosgen (1994) as well as some additional coefficients from the eastern...
Stepwise Flood Routing for Gated Reservoirs and Conjunctive Optimization of Hydroelectricity Income with Flood Losses
A six-stage operation policy for routing of flood hydrographs of return periods from 1.01 year up to the Probable Maximum Flood (PMF) for dams having gated spillways is suggested. The...
Evaluation of a Soil Vapor Extraction System: A Post-Audit Assessment
(No paper) Numerous sites contaminated with volatile organic compounds (VOC) have implemented soil vapor extraction (SVE) systems to remediate the unsaturated zone. The SVE systems have...
Dynamic Groundwater Remediation Design with Genetic Algorithms
In groundwater remediation design it has been shown that dynamic policies, in which the pumping strategies may vary throughout the remediation period, can result in more cost-effective...
Optimization of the Aquifer Remediation Costs and Design with Pulsed Pumping
(No paper) Pump-and-treat is a common technique for the remediation of contaminated aquifers. However, slow kinetic mass transfer at sites contaminated with organic compounds may reduce...
The Evolution of Florida Water Management
(No paper) The State of Florida has always been very cautious to protect it's natural resources which is the cornerstone of the State's economy. The availability to vast quantities of...
Robust Techniques for Extension of Streamflow Records
Longer hydrological records are required for the planning of water resource systems. Sensitivity of a system is studied under various scenarios of hydrological inputs to understand its...
Simplification of Detailed Models of Water Distribution Systems Obtained from GIS Systems
For a long time simplified models have been used to simulate the behaviour of large water distribution networks. Often, simplification has been carried out by removing small diameter pipes...
