The Use of Spread Sheets in Water Resources Planning
With the advent of 'spread sheets' in the microcomputer explosion, a tool is available for the first time to greatly simplify many engineering procedures. This...
Models of Border Irrigation for Flat Clayey Soils
Border irrigation is widely used for irrigating pastures in south-east Australia. Inadequate earthworks, design and operation of irrigation layouts have been major causes of waterlogging...
The Relationship of Benefits to System Size for Irrigation Projects
This paper presents a generalized linear programming (LP) and farm budget model for optimization of on-farm irrigation benefits resulting from variations in irrigation project size. The...
Considerations for Sizing Water Delivery Systems
The purpose of a water delivery system is to deliver irrigation water to a farm and its design should be based on meeting the requirements of farm water use. The rate, duration and frequency...
Irrigation District Management?Past, Present and Future
This paper reviews the significant changes in the policies and procedures followed by agencies formed to deliver irrigation water in the western United States generally and California...
Crop-Water Production Functions and System Design
A Task Committee to evaluate application of crop-water production functions to irrigation system design and management was established by the ASCE Irrigation Water Requirements Committee...
Economic Analysis Tools for Differential Inflation
Economic decisions based on a life-cycle analysis should consider differential increases or decreases in operation and replacement costs and benefits over the project or component life....
An Integrated Rehabilitation Procedure for Gravity Systems
Demands for an improved system combined with a more adjusted management mode are common in many projects where limited or strained budgets do not allow for a regular and secure water supply....
Forty Years of Computational Hydraulics?1960-2000
The definition of computational hydraulics as used herein is: the application of numerical methods for the solution of problems of hydraulic flows, largely as practiced by the civil engineering...
Coastal Zone '87
Coastal Zone '87 is the fifth in a series of multidisciplinary meetings on comprehensive coastal and ocean management. The papers included in this publication review technical...
Liberty Restored
The Outstanding Civil Engineering Achievement of 1987 is the restoration of the Statue of Liberty in New York Harbor. The restoration work included many engineering tasks that by themselves...
Design of Steel Transmission Pole Structures
This document has been carefully prepared in an effort to provide an authoritative source of information about effective design and fabrication of steel transmission pole structures. The...
Measures Against Wind-Induced Vibrations of Bridges
The design of very flexible structures, such as long-span steel bridges, are frequently governed by wind-induced vibrations. This paper introduces the present situation of the cable-supported...
Wind Buffeting of Cable-Stayed Bridges During Construction
Some of the dominant loadings on a cable-stayed bridge during construction are a result of the non-uniform vertical and horizontal gust forces on the deck and the associated dynamic response...
Prediction and Control of the Wind Response of Long-Span Bridges with Plate Girder Decks
The aerodynamic stability of plate girder decks and methods of improving it are discussed. The selection of an appropriate design wind speed for flutter is reviewed including the effect...
Flutter Derivatives from 14 Generic Deck Sections
The results of a series of wind-tunnel bridge-deck section-model experiments are discussed. Fourteen section models, seven with H-shaped cross-sections and seven with rectangular cross-sections,...
Stabilizing Winglet Pair for Slender Bridge Decks
This paper describes the effectiveness, as an aerodynamic damper, of a pair of winglets mounted parallel to, and clear from, bridge decks that might otherwise be aeroelastically unstable....
Wind Tunnel Aeroelastic Model Study of the Baytown Bridge (Steel Alternative)
Analytical and full bridge aeroelastic model studies performed to assess the aerodynamic stability of the steel alternative Baytown Bridge over the Houston Ship Channel are described....
Wind Tunnel Investigation of a Twin Deck Suspension Bridge
Wind tunnel measurements of the response of a twin deck suspension bridge to dynamic wind loads are presented. The investigation was concerned with the determination of the deck response...
Aspects of Wind and Earthquake Dynamics of Cable-Stayed Bridges
In the course of dynamic analysis of long-span cable-stayed bridges for the effects of earthquake and wind, a number of observations have been made that may be of interest to designers....
