Effects of Lateral Heading Flow Steadiness on Lateral Spillage
Hourly inflow and spillage rates from three lateral canals in the Imperial Irrigation District in Southern California were measured for seven months and subsequently analyzed to identify...

Explicit Stochastic Modelling of a Reservoir for Hydropower Production
A new reliability model for planning the operation of a multipurpose reservoir for hydropower generation and flood control, which considers the stochastic nature of inflows and power demand...

Improving Reservoir System Operations Under Water Rights Requirements
Successful reservoir operations planning largely depends on knowing the future inflow to the system; understanding the objectives of the reservoir system; and understanding the relationship...

Stochastic Optimal Control for Determination of Freshwater Inflows to Estuaries
The objective of the research is to develop estuarine system management models based upon discrete-time stochastic optimal control. An analytical feedback control law is given. The control...

Multiobjective Models for Determining Freshwater Inflows to Bays and Estuaries
This paper presents four multiobjective models for the estuary management problem, including goal programming, the epsilon constraint method, the surrogate worth tradeoff method and the...

A Nearshore Model for Cleveland CSO Remediation Design Selection
Three models were combined to analyze the fate of Combined Sewer Overflows (CSOs) in the Cleveland, Ohio area. Firstly, a 20 year hindcast of Lake Erie was used to find design storms by...

A Wind Driven Lake Circulation Finite Element Model for the Upper St. Marys River
The hydrodynamics of the Upper St. Marys River is simulated by a three dimensional steady state finite element model. The rigid lid and hydrostatic pressure assumptions are used in the...

Existing Sewer Evaluation and Rehabilitation
This manual, Existing Sewer Evaluation and Rehabilitation, Second Edition, provides general guidance and serves as a source of information...

Development of Self-Organizing Traffic Control System Using Neural Network Model
This paper is concerned with developing a self-organizing traffic control system using a neural network model, a multilayer network model. The neural network inputs the control variables,...

A Computer Model for Multiplant Hydroelectric System Simulation
An interactive computer model of a multi-plant hydrothermal electric power generating system has been developed that roughly captures the main features of the British Columbia Hydro system....

Multiobjective Models for Determining Fresh Water Inflows to Bays and Estuaries
This paper presents two formulations of multiobjective models for the estuary management problem that are based on goal programming procedures. The multiobjectives are selected to be minimum...

Stochastic Reservoir Operation under Drought with Fuzzy Objectives
Biobjective reservoir operation under drought conditions is investigated using stochastic dynamic programming. As both objectives (irrigation water supply, water quality) can only be defined...

Watershed Effects on the Value of Marshes to Fisheries
Watershed size and rainfall patterns are among the factors that influence the extent to which fishery species use estuarine marshes as nurseries. We examined three Texas bays with different...

Study of the Circulatory and Salinity Changes in Galveston Bay, Texas by Using a Three-Dimensional Hydrodynamic and Transport Model
The effects of tides and freshwater inflows on the circulation and salinity changes in Galveston Bay are investigated numerically by using three-dimensional hydrodynamic and transport...

Impact of Surge Irrigation on Furrow Water Advance
Surge irrigation was compared to continuous flow in Nebraska from 1983 - 1990. As a result of surge irrigation, advance inflow times were reduced an average of 20 percent compared to continuous...

Impacts of Potential Climate Change on Colorado-Big Thompson System Operations
The objective of this study is to examine the response of the Colorado-Big Thompson (CBT) system to specific local changes in climate, using the model CBTAOP to project the operating plan...

Structural and Ice Effects on Salt Water Marsh Hydrology
This study focussed on a New England salt water marsh in which the construction of two drainage structures (culverts) have significantly affected the marsh hydraulics. The result is the...

New Methodology for Optimization of Freshwater Inflows to Estuaries
The objective of this paper is to present a new methodology for determining the optimal fresh water inflows into bays and estuaries to maximize fish harvest while satisfying the freshwater...

Operational and Structural Optimisation of Hydraulic Structures for Light Liquid Removal
The removal efficiency of light liquid separation schemes is determined by the hydraulic inflow conditions, the inflow fluid properties and the separator hydraulics. The relating set of...

Sediment Deposition in Jennings Randolph Reservoir, Maryland and West Virginia
The watershed of the Jennings Randolph Reservoir covers 263 square miles of mountainous terrain in western Maryland and West Virginia. Sedimentation studies performed prior to impoundment...
