Towards a Better Simulation of Sea States for Modelling of Coastal Structures
In the last fifteen years, techniques of wave generation have advanced to such an extent that it is now possible to exercise controls of parameters such as wave grouping, wave asymmetries,...
Reshaping Breakwaters on the Stability of Roundheads and Trunk Erosion in Oblique Waves
The stability of a berm type breakwater (sacrificial breakwater) was tested in a 3-dimensional model at The Hydraulics laboratory, Department of Civil Engineering, University of Aalborg....
Hydraulic Performance of Berm Breakwaters
In recent years, the concept of unconventional rubble mound breakwaters, i.e berm breakwaters, has gained much attention among researchers and engineers as an economical method to build...
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...
Design/Construct Contract Speeds Bridge Job
In the name of time and money savings, Pennsylvania DOT is building a bridge using a modified turnkey contract. In contrast, the standard approach is first to design the bridge, then ask...
Costing Contingencies
Estimating the cost of constructing a tunnel is an art rather than a science. The unknowns are too great to predict costs relianblbly. On the other hand, owners need cost estimates in...
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...
Contract Documents: Lessons from Litigation
Perfect contract documents and a flawless design are uncommon. Given the complexity of many construction projects and the advances in technology, it is not surprising that contract language,...
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...
Impact of International Competitiveness on Construction Technology
Both international and domestic construction markets are changing and forcing changes in construction technology. These proceedings contain six papers from an ASCE technical session on...
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...
