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...
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...
Facilities Planning in the Caribbean a Case Study
Culebra has significant problems of water scarcity and poor wastewater treatment. In 1984-1985, a formal Environmental Impact Statement (EIS) was prepared for improved wastewater treatment...
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...
Irrigation in Mexico
Mexico has a great historic tradition in the construction of works for irrigation; irrigated agriculture has been practiced since the pre-hispanic epoch. The development of hydro-agriculture...
Irrigation Development in Alberta, Canada
Agricultural production in the southwestern part of the Canadian prairie provinces is limited by insufficient rainfall for optimum crop production. To overcome this moisture deficiency...
Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....
Strategy for Ground Water Planning
Though the percentage of ground water development is only 40%, many areas of India are over developed, where water tables are falling rapidly, due to over pumping. In some areas the surface...
Colorado High Mountain Aquifer Study
This paper describes the potential for formulating water projects in Colorado using the storage capability of high mountain glacial aquifers. Although a terminal moraine provides a natural...
Prediction of Sediment Yield for Southern California Watersheds
The objective of this paper is to present a scientific method based on multiple linear regression analysis between the sediment yield per square mile and a number of physically realistic...
Hansen Dam Sediment Modeling Study Impact of Water Supply vs. Flood Control Operational Modes on Sediment Deposition in the Reservoir Area
The analysis of scour and deposition in Hansen Reservoir by modeling the interaction between the water-sediment mixture, sediment material forming the stream's boundary and...
Annual Sediment Loads of Illinois Streams
Incorporation of sedimentation surveys for 24 Illinois lakes was needed to provide somewhat long-term average sediment yields of Illinois streams. For each suspended sediment station a...
Effects of Irrigated Agriculture on Groundwater Quality in the Corn Belt and Lake States
Irrigation of croplands has the potential to increase the rates at which water soluble substances are leached from soil into underlying aquifers. This paper evaluates the impact of irrigated...
