Arranged Delivery Schedules
The method of delivery of irrigation water to farmers from irrigation districts vary considerably from one project to another. Rotation delivery systems usually place too many restrictions...

Demand Irrigation Schedules
This class of schedules consists of Demand and Limited Rate Demand. They need no communication system and can satisfy the on-farm needs with negligible constraint. The Demand schedule...

Implementation and Management of a High Technology Irrigation System
Eastern Oregon Farming Company (EOFC) irrigates 12,000 acres using a fully pressurized irrigation system. In 1981, the system was operated with minimal flow and pressure measurements and...

Instrumentation: Canal De Provence
A report describing the Canal de Provence and its specific hydraulic regulation system, 'dynamic regulation', is presented in another conference paper. The present...

Air Chamber Surge Tanks in High Head Hydro Plants
The U. S. Army Corps of Engineers Alaska District considered an air chamber during the design of the 'Crater Lake phase of the Snettisham Project near Juneau, Alaska. A conventional...

Time Variability of Suspended Material Concentrations in Estuaries
The concentration of suspended materials (SMC) within estuarine systems varies in response to a variety of factors. This variability complicates sampling SMC and establishes particular...

Design and Performance of a Siphon Penstock
Siphons can be a cost effective alternative to more traditional means of conveying water to hydroelectric turbines. The City of Ann Arbor, Michigan selected a siphon as the most cost effective...

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...

Modeling the Effect of Weirs on Reservoir Releases
A computer model was developed to examine the influence of weirs on the rise of water levels and increases in velocities from reservoir releases. The model allows for investigation of...

Capacity Expansion of Water Distribution Systems?A Case Study
Capacity expansion and necessary capital improvements to meet the water supply demand for years 1990-2020 for the U. S. Route 1 corridor development from South Brunswick to Princeton,...

Hydraulic Model to Improve Debris-Handling Capability of Waterford Unit 3 Intake Canal
A 1:30 scale model was used to test the effectiveness of various modifications to the Waterford Unit No. 3 intake canal. The objective of the study was to assist in the development of...

Low Head Hydropower Finite Element Analysis
Finite element analysis provides a means of predicting the flow conditions resulting from the operation of a proposed hydropower facility. The results of a finite element flow analysis...

Methods for Specification and Verification of Hydraulic Design in a Turnkey Construction Contract
The project site is at the Hannibal Locks and Dam at New Martinsville, West Virginia. The existing project, a Corps of Engineers' (Corps) facility built in the 60's...

Real Time Modeling to Meet Flow Requirements at a Fossil Steam Plant
A real time modeling system has been developed to schedule hydropower operations in order to comply with discharge permit requirements at a downstream fossil steam plant. The modeling...

Delivery System Management Via Dynamic Programming
Management of irrigation water delivery systems may involve allocating limited water supplies over both time and space under uncertain future demands. The physical delivery systems are...

The Animas-La Plata Project Cost Sharing Agreement
The United States Congress required a cost-sharing agreement between the project beneficiaries and the Federal government. Under this agreement of June 30, 1986, the project will be constructed...

Water Supply Forecasting and Irrigation Demand
The Soil Conservation Service (SCS) Snow Survey Program makes periodic seasonal streamflow forecasts at over 500 major points in the western states. These forecasts are the basis for making...

Physical Model Verification of a Coastal Discharge
A 1:75 scale physical model of a thermal discharge into a rocky, semi-enclosed bay was verified against extensive field data. The model accurately reproduced the prototype temperature...

Lights Out at Caribou
The Caribou powerplant restoration is one of the projects to receive an Outstanding Civil Engineering Achievement Award of Merit. On February 24, 1984 a rock slide on the ridge above the...

Overview of the Guidelines for T/L Structure Loadings
This section introduces a reliability based design methodology that forms the framework for the loading guidelines. A Load and Resistance Factor Design (LRFD) format is presented for the...
