Outlet Structure Hydraulics
Current detention basin design procedure is to design the outlet structure for two or more return periods. This is sometimes done by combining weirs and/or orifices of various sizes and...

An Optimization Approach for Locating Sediment Ponds in Stripmined Areas
In this study, a mathematical model which can predict erosion from a watershed and incorporated into an optimization model has been investigated. The Erosion-Deposition Model (EDM), which...

Optimization, Simulation and Multiobjective Analysis of Operating Rules for Reservoir Systems
In this paper, three steps are proposed for establishing reservoir operating rules which can be used in real-time without flow forecasting. In the first step, optimization models are used...

Water Resources Systems Planning: Differential Dynamic Programming Models
A Monte Carlo optimization methodology is presented for water resources systems. The planning model define the optimal storage and release policies for the reservoir system. The optimization...

On-Site Microcomputer Control of a Combined Sewer Overflow Diversion Structure
This paper describes the design of an inexpensive system for controlling combined sewer overflows using on-site equipment (raingauges, flow gauges, automatic gates, and microcomputers)....

Verification of a Supply Reliability Model
Three versions of an analytical model for estimating the reliability of a water supply system including capacity components and small amounts of finished water storage are presented. Simplifying...

Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...

Coupling of Hydrodynamic and Water Quality Models
Long term, multi-dimensional water quality modeling in estuaries and coastal embayments using a directly linked hydrodynamic and water quality model can be prohibitively expensive. In...

The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...

Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...

A Unified Hydrodynamic-Water Quality Model
To understand the cause-effect relationships controlling water quality in dynamically narrow estuaries, a time dependent branching, laterally averaged (longitudinal and vertical) hydrodynamic...

NID Water Supply and Hydropower Operation Model
A basic requirement of CH2M HILL's Raw Water Master Plan for Nevada Irrigation District (NID) was to determine the dependable water supply available from the District's...

Multivariate Modeling of Hydrological Time Series for Generation of Reservoir Operating Rules
A multivariate model and a disaggregation model are used in this study to generate annual and monthly time series of streamflow data for multiple sites. The parameters of the models are...

Reservoir System Simulation Through Network Flow Programming
A generalized reservoir system simulation model that makes use of a network flow programming technique has been developed for use in planning and operation studies of multi-purpose water...

Optimal Weekly Operation of a System of Three Multipurpose Reservoirs
Marion, Council Grove, and John Redmond Lakes located in the Upper Neosho-Cottonwood River basin are an integral part of the State Water Marketing Program of Kansas. In addition to water...

Engineering and Policymaking: The Platte River in Nebraska
Substantial conflict exists over proposed water projects in the Platte River Basin of Nebraska. A computer simulation model, representing the engineering and environmental dimensions of...

Modeling to Generate Alternatives: A Review
Modeling to generate alternatives (MGA) is a species of multiobjective programming in which some relevant objectives and perhaps some constraints are deliberately left unquantified. The...

Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...

Unique Flood and Drainage Problems in Los Angeles
Storm drainage for the coastal cities has to traverse highly used sandy recreational beaches. Due to new requirements on the construction of storm drains to the ocean, a beach outlet has...
