Modeling Reliability in Water Distribution Network Design
The component failures in a water distribution system include pipe breaks, pump failures, valve failures, storage malfunctions, etc. The reliability of these components has an effect upon...

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...

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...

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...

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....

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...

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...

Impact of Irrigation on Groundwater Quality in Humid Areas
The GLEAMS Model (Groundwater Loading Effects of Agricultural Management Systems) was applied to estimate the effects of soil, planting date, irrigation level, and pesticide characteristics...

Conjunctive Use Project in Beebe Draw, Co.
A geologically and hydrologically unique alluvial ground water basin, and the hydrologic interaction among aquifer, ground water pumping for irrigation, and the surface water storage and...

Integrated Wastewater and Sludge Treatment in a Tree Farm
A system which integrates land treatment of wastewater following primary sedimentation with tree production and sludge composting was evaluated for its land requirements, costs, and energy...

Math Modeling of Mixing Zones in River Systems
A numerical mixing zone model was developed utilizing an implicit finite difference method with a weighted numerical scheme. The model was based on the two-dimensional advection-dispersion...

Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...

Management Strategy
Meanders of sinuous streams are often cut off by natural action or by man in order to improve conveyance or navigability. Cutoff bendways, as long as they remain aquatic, provide extremely...
