The Nebraska Chemigation Cat?1987 in Review
The Nebraska Chemigation Act was signed into law in April of 1986 with requirements effective January 1, 1987. The Act is one of the most comprehensive pieces of chemigation legislation...

Advanced Chemigation Systems for Environmental Safety and Groundwater Protection
A multifunction irrigation system has been developed which utilizes a separate dynamic in-canopy nozzle system for chemical application. Testing the system with a lithium tracer on four...

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...

Preliminary Results of the Department of the Interior's Irrigation Drainage Studies
The Department of the Interior, in 1986, began irrigation drainage studies in nine areas in seven Western states to determine whether irrigation drainage has caused or has the potential...

Trace Elements and Pesticides in Salton Sea Area, California
Concentrations of numerous potentially toxic trace elements and pesticides were determined in water, sediment, and biota from the Salton Sea area in southestern California. Comparison...

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 (Ng) and bed stability (Nh) have been developed. Optimum placement of...

Riprap Design by Modified Safety Factor Method
The Safety Factor method for designing riprap is based upon straight forward physics combining rock properties and flow characteristics. M.A. Stevens developed the method by summing the...

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...

Analysis of Onsite Measurements of Scour at Piers
Existing onsite measurements of local scour at bridge piers were assembled and analyzed to obtain an equation that predicts the expected maximum depth of local scour at a bridge pier....

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...
