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...

Evaluation Procedures for Hydrologic Safety of Dams
Procedures are proposed for selecting the safety design flood for both new and existing dams. The procedures are based on a quantitative risk assessment in which the likelihood and consequences...

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...

The Effect of Seeding on Convective Cells in West Texas
The effect on convective cells of randomized seeding for dynamic effects in the Southwest Cooperative Program is addressed. Analysis of three-dimensional, volume-scan, radar data using...

Determining Transit Losses for Water Deliveries by Use of Stream-Aquifer Models
Hydrologic modeling of stream-aquifer interaction commonly has been used to quantify transit losses associated with water deliveries, such as those from reservoir storage. This technique...

Conveyance Characteristics of Natural Channels in Wyoming
This paper addresses the quantification of instream or conveyance losses of water being transported within natural stream systems in Wyoming using a net total loss and incremental loss...

Wetland Impacts of Center Pivots in Wheeler Co., NE
This paper describes an investigation of wetlands impacts from an intensive center-pivot irrigation operation in a 17,000 acre portion of Nebraska's Sandhills region. Well...

Variability of Copper in the International Reach of the Similkameen River, British Columbia
All total copper concentrations measured in soft water during spring freshets were above the Canadian Water Quality Guidelines. Approximately 57% of all 108 observations over the three-year...

Irrigation Intervention Analysis of Drainage SAR
G.E.P. Box-G.M. Jenkins time series analysis, with irrigation applications as an intervention function, was used to study temporal and spatial variabilities of sodium adsorption ratios...

Developing a Training Program for Inspectors
The reasons for failure of engineering works are many and varied. An inexperienced or poorly trained construction inspector can be a contributing element in cases of failure. The Bureau...

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...

Dam Seepage Analysis Using Artificial Intelligence
The paper discusses an interactive advanced decision support system (ADSS) which is being applied to analyzing seepage from embankment dams. The development of a prototype knowledge base,...

Atrazine in Subsurface Drain Water in Southern Louisiana
Atrazine was applied preemergent to corn on subsurface drained and undrained plots. Atrazine soil concentration and concentration and loss in drain water were determined for 243 days after...

Pesticide and Nitrate Movement Under Conservation and Conventional Tilled Plots
Carbofuran, alachlor, atrazine, nitrate and bromide (a tracer) were applied to plots with conventional and conservation tillage. During the early part of the growing season the conservation...

A Portable Bowen Ratio System for ET Measurements
The AZET system developed at the University of Arizona is designed to measure evapotranspiration (ET) in arid zone environments, using the Bowen ratio model. The system consists of a set...

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'...

A Lawyer's View of Engineers' Responsibility
When presented with a case involving damaged property, a lawyer typically will seek to determine the point of the failure and then work backwards in an effort to analyze each of the factors...

Flow Measurement Using a Digital Pressure-Time Method
This paper describes flow measurements performed by TVA's Engineering Laboratory as a part of absolute efficiency measurements of the two units at the Great Falls Hydro Plant....

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...
