This book contains sixteen papers presenting applications of expert system technology to civil engineering problems with emphasis on microcomputer implementations. It is divided into four...
Measured Performance of Shallow Foundations
The seven papers included in this book document the field performance of shallow foundations. Five of these papers present foundation settlements caused by the compression of the subsoil,...
Infrastructure and Marketing in Water Resources
Marketing and infrastructure are two areas of growing interest and importance in engineering. Nearly every engineering discipline now uses some form of marketing to promote its products...
Soil Properties Evaluation from Centrifugal Models and Field Performance
The performance of geotechnical projects is dependent upon the appropriateness of the design theory to the boundary conditions, and the characterization of the soil properties used in...
The Changing Federal/State Relationship in Water Resources: An SCS Perspective
Since 1935, the Soil Conservation Service (SCS) has worked directly with state and local agencies, and individual landowners, to conserve and develop the Nation's soil and...
Changing Federal/State Water Resources Roles
As federal agencies such as Reclamation undertake change on national and regional levels, the priorities and programs of state and local groups may, in turn, be affected. Increased coordination...
Changing Role Between State and Federal Agencies
The paper discusses the title subject from the perspective of someone working in a state agency. The federal agencies discussed include the U.S. Army Corps of Engineers, Bureau of Reclamation,...
The Changing State Role in Water Management
The roles of the federal, state, and local governments in developing and managing the nation's waters are dynamic. They continue to reflect shifting social goals and policies....
Colorado River Municipal Water District Weather Modification Program 1971-1986
The Colorado River Municipal Water District (CRMWD) has sponsored a rain enhancement program on summertime convective clouds in West Texas since 1971. Silver iodide is used for cloud base...
Oklahoma Southwest Cooperative Program?An Update
In an effort to meet present and future regional water needs, the Oklahoma Water Resources Board and the Texas Water Commission (TWC), the Oklahoma effort has addressed three basic components:...
High Plains States' View on Weather Modification
The need for a critical analysis of all weather modification efforts has continued to be expressed during the ten years of the North American Interstate Weather Modification Council (NAIWMC)....
Chemigation Backflow Prevention Assemblies
Chemigation with sprinkler irrigation systems is widely used throughout the United States. One potential environmental hazard of this practice is the point source water contamination due...
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...
Potassium Fertigation in Drip Irrigated Peppers in Puerto Rico
Three potassium fertigation rates (T1 = 100%, T2 = 60%, T3 = 30%) via trickle irrigation, fertilization rates (T4 = 100%, S1 = 100%, S2 = 50%, S3 = 0.0) and nonfertilization (T5 = 0.0)...
Drip Irrigation for a College Container Nursery
A drip irrigation system was installed by students during the summer of 1987 at the Ohio State University Agricultural Technical Institute, Wooster. The goals of this project were for...
Nebraska's Special Protection Area Program
The designation of a Special Protection Area (SPA) under the program allows the state and local natural resources districts to move from the voluntary to the regulatory arena in addressing...
Simple Furrow Advance Ratio Evaluation Technique for Upgrading Management
A simple procedure using the Advance Ratio (AR) is presented. It utilizes on-farm gathered information of advance time, water application time, and depth applied for furrow irrigated field....
Furrow Irrigation Performance Using Real Time Control
Computer simulations were conducted, using a simple feedback control algorithm, to determine the potential for improvement of irrigation performance using real-time feedback control. Field...
