Maintenance of Automated Pumping Plant Controls
Westlands Water District, located in the Central San Joaquin Valley in California (Fig. 1) includes over 600,000 acres of agricultural land and is part of the San Luis Unit of the U. S....
Overview of Financial and Economic Considerations
The financial and economic analyses of plans to rehabilitate and automate irrigation water delivery systems are complex technical exercises that require the expertise of professional economists...
Financing Options for the Operation, Rehabilitation, and Automation of Irrigation Water Delivery Systems
The paper discusses potential sources of financing for irrigation improvements and outlines many methods for securing funds. Irrigators who are in need of funds to improve or repair their...
The Urbanization of the Salt River Project
The Salt River Project (SRP) is one of the nation's oldest and most successful agricultural reclamation projects. Formed in 1902, its initial function was to manage the surface...
Modeled Effects of Hydraulic Mixing Devices on Reservoir Water Quality
A two-dimensional reservoir water quality model was used to evaluate effects of hydraulic mixing devices on release and water quality. Seasonal simulations of Douglas Reservoir water quality...
Salinity Intrusion in Louisiana Coastal Canals
Field data of the salinity intrusion in three Louisiana coastal canals were presented. In these canals, the mixing state can be categorized as, in general, well mixing at the Gulf side...
Simulation of Sediment Transport in Coastal Water
The sediment-contaminant transport code, FETRA, coupled with the hydrodynamic model, CAFE-I; and the wave refraction model, L03D; were applied to Pacific coastal water. The FETRA model...
Carichar?Mobile Bed Modeling with Graded Sediments
CARICHAR is a new system used for the computation of sediment transport. The coupled calculation of both water and graded sediments transport allows the simulation of sorting and armoring...
Hydraulic Availability Evaluation of Urban Water Distribution Systems
This paper presents a concept for evaluating urban water system reliability using an extended period hydraulic simulation model in conjunction with mechanical availability analysis. Reliability...
Joint Consideration of Pipe Breakage and Pipe Flow Probabilities
Two issues of distribution network reliability, namely, probability of pipe failure and probability of the design flow being exceeded have been discussed. Expressions containing measures...
Optimal Design of Large Scale Water Distribution Systems
This paper presents a methodology for the design of least cost water distribution systems. The advantage of the formulation compared to the other techniques in the literature is that it...
Management of Water Distribution System Components
The purpose of this study is to 1) analyze main break failures and 2) incorporate other drinking water distribution system components into a data base management structure for reliability...
A Semianalytical Method for Solving Unsteady Flow Equations
This paper proposes a method that uses conjunctively the Laplace transform for continuous time and finite element for spatial discretization to solve unsteady flow equations. Laplace transforms...
Water Distribution System Design by Chance-Constrained Model
The objective of this paper is to present an optimization model for the design of water distribution systems considering the uncertainty in required demands, required pressures, and pipe...
Analytical Simulation of Bulk Water Supply Network Reliability
The authors present an analytical method for estimating failure probabilities for a bulk water supply network with spatially dispersed supply, demand, and storage. The method examines...
Reliability Analysis of Pumping Stations and Storage Facilities
The methodology presented for pumping stations is based upon three models: a supply model, a demand model, and a margin model. The supply model considers so-called states of a system which...
Model for the Optimal Rehabilitation and Replacement of Water Distribution System Components
The objective of the model presented is to determine the minimum cost solution, given the nonlinear nature of the equations required to describe the cost and the hydraulics of a water...
Comparing Two Estuarine Mass Transport Models
Two simplified mass transport models for partially mixed estuaries were evaluated using data from the Patuxent and James Estuaries. The first of the models was developed by Pritchard in...
Basin: A Simple Yet Many Faceted Model for Estuarial Impoundments
BASIN is a hydrodynamic and water quality model designed to provide a simplified analysis of flows and constituent concentrations in both tidal and non-tidal water bodies. BASIN is excellent...
Network Analysis for Water Supply Reliability Determination
The availability of water at a point in a distribution network is expressed in terms of the reliabilities of the components which comprise the different paths to the point from the source....
