A Stochastic Seismological Model in Earthquake Engineering
Recent studies of source mechanisms and wave propagation models enable one to generate strong motions based on deterministic source and source-to-site characteristics. The normal mode...
Autoregressive Model of Spatially Propagating Earthquake Ground Motion
An autoregressive random process model was used to investigate a simulation method of spatially and temporally variative ground motion when characteristics of motion are prescribed by...
Effect of Air Gap on Platform Reliability
A simplified reliability study of the effect of lateral wave forces impacting the deck of a fixed platform is presented. The reliability of the deck legs, considered the primary resistance...
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,...
Reef Breakwater Response to Wave Attack
A method of predicting stability of a class of low-crested rubble mounds referred to as reef breakwaters is presented. Findings are based on a study which included an extensive series...
Rock Armouring to Unconventional Breakwaters: The Design Implications for Rock Durability
This paper identifies the need for quantitative durability testing of rock for use on dynamically stable rock armored slopes. The derivation and use of a suite of engineering tests for...
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...
Application of Computational Model on Berm Breakwater Design
The development of a computational model on dynamic stability is summarized. The model is able to predict profiles of slopes with an arbitrary shape under varying wave conditions. The...
Performance of a Berm Roundhead in the St. George Breakwater System
A new harbor under construction on St. George Island in Alaska's Bering Sea is using the berm breakwater concept for protection from wave attack. Three breakwaters are included...
Berm Type Armor Protection for a Runway Extension at Unalaska, Alaska
A proposed runway extension located on the Aleutian islands was designed to withstand forces of Bering Sea storm generated waves using a unique armor protection concept. The proposed runway...
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...
Comprehensive Rehabilitation Results From Stege Sanitary District
Seven sewer agencies, including Stege Sanitary District, in the East Bay of the San Francisco Bay Area embarked on a 20-year capital improvement program in 1987. The 300 million construction...
Arctic Coastal Processes and Slope Protection Design
Cold regions present special challenges for civil engineers. The papers in this book address arctic coastal processes and slope protection design. The first part of the book focuses on...
Use of the Penman Equation in Inter-Mountain Valleys
H.L. Penman equation as well as the J.L. Monteith version of this equation were compared under the advective conditions of the Grand Valley of Colorado. The wind function in the general...
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...
Large Scale Evapotranspiration from Remotely Sensed Surface Temperature
Large scale evapotranspiration requires a blend of ground-based and remotely sensed data. To evaluate the utility of the extension from a small to a large scale, studies were conducted...
Measurement Systems in the Hapex-Mobilhy Regional Evapotranspiration Experiment
The HAPEX-MOBILHY (Hydrologic-Atmospheric Pilot Experiment - Modelisation du Bilan Hydrique) regional evapotranspiration experiment was conducted in the south-west of France during the...
Bulk Stomatal Resistance in Operational Estimates of Evapotranspiration
General relationships for estimating canopy or bulk stomatal resistance and aerodynamic resistances of grass and alfalfa reference crops for use in the Penman-J.L. Monteith equation are...
Ultrasonic Flow Meter Testing
Six ultrasonic flow meters were tested in a hydraulics laboratory. Accuracies better than 2% were obtained with two transit-time meters on 14 inch diameter steel tubing. Poorer accuracies...
