Parallel and Distributed Processing in Structural Engineering
Parallel processing is emerging as an effective approach to large scale structural engineering computations. The papers included in this book cover vibration analysis using a parallel...

A Summary Description of Design Criteria, Codes, Standards, and Regulatory Provisions Typically Used for the Civil and Structural Design of Nuclear Fuel Cycle Facilities
A summary of design criteria, codes, standards, and regulatory provisions applicable to the civil and structural design of the eight principal facilities of the nuclear fuel cycle are...

Proposed Improvements in Lateral Canal Operations
Uniform and flexible supplies of irrigation water are required for farmers to make the best use of their on-farm application systems. Results of a study of deliveries at the lateral canal...

Random Characteristics of Sediment-Laden Flows and the Techniques of Effective Sediment Exclusion on Dujiangyan Irrigation Project in China
The irrigation system is over 2,200 years old and discharges water at a rate of 340-740 m³/s from the Minjiang River. The average slope of the river...

Alternative Dispute Resolution in Water Resources Management
In recent years a variety of techniques have been advocated to resolve natural resource conflicts. These approaches have collectively been termed 'Alternative Dispute Resolution'...

Geotechnical and Hydraulic Stability Numbers for Channel Rehabilitation: Part II, Application
Stability numbers for bank stability (N_g) and bed stability (N_h) have been developed. Optimum placement of...

The USDA Water Erosion Prediction Project
New generation water erosion prediction technology is being developed by the USDA Water Erosion Prediction Project (WEPP). The new technology is expected to replace the Universal Soil...

Scour Downstream of the Straight Drop Spillway
Tests made to determine the effect of high tailwater and long duration flows on scour downstream of the straight drop spillway stilling basin are presented in this paper. Results are presented...

Local Scour Downstream of a Tunnel Outlet Structure
The local scour downstream of two different types of outlet structures is studied in laboratory experiments with an alluvial sediment. The outlet structure terminates a hydraulic model...

A Model of Flow in Regulated Open Channel Networks
A model (NETWORK) is presented for the simulation of unsteady flow in regulated open channel networks. The operation of hydraulic structures, such as gates and weirs, are simulated as...

Channel Response to SCS Type-C Grade-Control Structures on Burney Branch, Mississippi
Five SCS Type-C grade-control structures were installed in Burney Branch in 1980 to remove 59.4 feet (18.1 m) of grade. The performance of the structures was evaluated in 1984 after they...

Analysis of Spillway Failures by Uplift Pressure
Results of a model study to evaluate the development of uplift pressures beneath concrete chutes are presented. Two spillway failures are described to support the study results. Common...

Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...

Mathematical Model of Wave Induced Pressures
A two-dimensional, implicit finite difference model was built to compute surface wave induced pressures under a gravity base foundation. The results showed considerable wave attenuation...

Performance Evaluation of Channels Stabilized with ARS-Type Low-Drop Structures
Field and hydraulic investigations of seven ARS-type low-drop grade-control structures located in Mississippi indicate that most of the structures become submerged during flows with recurrence...

Gas Transfer at Hydraulic Structures
Field measurements of gas transfer at hydraulic structures are notoriously difficult and imprecise. A technique which measures the transfer of hydrocarbon tracer gases has been tested...

Dam Safety, Yes.; But What About Safety at Dams?
Design and construction of safe structures are the professional obligations of hydraulic engineers. However, there are environmental dangers with safe structures which engineers often...

Hydraulic Effects on Swimming Fish in Fish Passage Structures
The implications of profile drag, weight, and buoyant forces on energy and power requirements of fish swimming through fish passage structures are considered. Where hydraulic grade lines...

Flow Through Fish Bypass Intakes
Hydraulic and computational fluid dynamic models were used to investigate the cause of the unequal intake flow distribution observed entering the three vertical intakes of the patented...

Physical Model of Local Scour at Grade Control Structures
A physical model of local scour occurring at grade-control structures was operated at an undistorted Froude number prototype-model scale ratio of 1:4. The maximum unit discharge in the...
