Experimental and Historical Verification of the Performance of Naturlly Armouring Breakwaters
A series of hydraulic model test were carried out to investigate the mechanism by which naturally armoring breakwaters, that is breakwaters in which the initial profile is adjusted into...

The Development of a Design for a Breakwater at Keflavik, Iceland
A breakwater design was developed to be built using local quarried rock and relatively simple construction methods. The design significant wave height was 5.8 and the maximum depth of...

The Design and Construction of a Mass Armoured Breakwater at Hay Point, Australia
The design and construction of a prototype mass armored breakwater is briefly described. The paper also explores the practicality of allowing the progressive interaction of design, physical...

Unconventional Rubble-Mound Breakwaters?Concerns
A Seminar on Unconventional Rubble-Mound Breakwaters was held in Ottawa, Canada, on the 15th and 16th of September 1987. This paper is an attempt to summarize the general discussion that...

Computing in Civil Engineering
Microcomputers to Supercomputers
This book contains papers presented at the Fifth Conference on Computing in Civil Engineering. Computer applications in specific disciplines are covered. These include construction engineering...

Drawing up Waterproof Curtains
Curtain wall damage has recently become the number one source of building owner complaints. Until wall systems are designed with backup water collection systems and other details, leakage...

Considerations in the Design and Installation of Horizontally Drilled Pipeline River Crossings
The authors will present a review of directionally controlled horizontal drilling techniques for pipeline installation by describing the state-of-the-art of the process vis-a-vis subsurface...

Pipeline Rehabilitation with Polyolefin Pipe
This paper provides an introductory discussion on the rehabilitation of a deteriorated pipe structure by insertion renewal with continuous lengths of polyolefin pipe. This sliplining or...

The Applicability of U.K. Sewerage Rehabilitation Techniques to the U.S.
The total length of public sewers in the UK is 160, 000 miles and in recent years there has been increasing concern over their conditions. Research spearheaded by the Water Research Centre...

The Cause of the Johnstown Flood
The Johnstown flood occurred in 1889, when an earth and rock dam failed during a record rainfall in eastern Pennsylvania. The flood was one of the worst civil disasters in the U.S.; 2,200...

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...

Evaluation of Infiltration Equations Used in Surface Irrigation
Computer simulations of an irrigation event were conducted using 6 full hydrodynamic models. All 6 models used the same surface flow equations and a different infiltration component. The...

Hydraulic Studies of Surface Drainage from Level Furrows
Field studies have been completed to quantify the surface drainage phenomenon from level furrows which were rapidly flooded and then drained from the inlet end of the furrow. The proportion...

Needed Social, Cultural and Design Changes to Successfully Manage Nigerian Surface Irrigated Projects
The aim of this paper is to illustrate the broad nature of problems associated with the faulty initial designs of water distribution network and irrigation methods and poor participartion...

A Method for `Warped Surface' Land Forming Design
Most approaches to land forming are based on a plane surface design which in some cases may result in prohibitive costs or excessive removal of top soil....

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...

The Social Sciences and Water Resources Management
With support from the National Science Foundation, a committee of 15 persons met in Washington, D.C. in 1985 to begin the process of assessing the past and future role of the social and...

Social Science, Engineering and Water Resources Management: A Perspective
This paper shares a framework or context for professional activities of social scientists in water resources management. It emphasizes the positive opportunities for helping and not simply...

Obstacles to the Use of Social Science Analysis in Water Decision-Making, or Where's the Demand for Social Science Input?
The paper identifies characteristics of both the public decisionmaking process and the methods of social science research that result in social science inputs having little influence on...
