An Update on Corps of Engineers Activities Along the California Coast
Preservation of shorelines around the nation has assumed dramatic importance for the Corps of Engineers and is exemplified by the early attention focused on California's beaches....
Marine Geological Studies on the Coastal Zone of Kerala
The largest of the estuaries in Kerala, the Vembanad lake formed by the backwater, has been investigated in detail with reference to bathymetry, sediments and geochemistry. A considerable...
Erosion of the Nile Delta Coast
The construction of the High Aswan Dam has resulted in a total absence of River Nile flow into the Mediterranean, and a corresponding loss of the sediment source for the Delta. However,...
Experimental Study on Sandbag Stability and Runup
Sandbag model tests are performed in a wave flume to examine the effects of berm-type slopes on the stability of sandbags and wave runup as compared to uniform slopes. Measurements of...
Designing the Fisherman's Wharf Area, San Francisco Harbor Breakwater
The Fisherman's Wharf Breakwater Project stands out as an example of a complex structure requiring the planning and design talents of the U. S. Army Corps of Engineers (COE)...
Reef Type Breakwaters for Shoreline Stabilization
The function of reef type breakwaters as a shoreline stabilization measure and the response of the shoreline to these structures are discussed. The application and effectiveness of reef...
Coastal and Ocean Resources for Energy Development
There has been a growing interest in renewable alternative sources of energy. An increasing effort is being directed towards the problem of extracting energy from the world's...
Nonlinear Deformation and Bispectral Change of Random Gravity Waves on Sloping Bed
A WKB-perturbation method is applied to the deformation of random gravity waves in water of slowly varying depth. In the present analysis, a spectral representation of WKB-type is assumed...
Wave Beach Interaction
This paper gives a derivation of the modification factors of wave amplitudes due to the effect of pure shoaling, friction, percolation and their combined effect. The resulting expressions...
A Transformation Technique to Generate a Shallow-Water Directional Wave Climate
The shallow-water wave data must be computed as to be representative of a sufficient length of coast to be useful for most projects, while sufficiently large to filter out many spurious...
A Preliminary Study on the Comprehensive Exploitation of Coast Zone Resources in the Southern Fujian
The Pacific tidal wave intrudes the South China Sea through the Bass Strait and travels northward as an 'upgoing wave' to Taiwan Strait affecting the Southern...
Quantifying Florida's Coastal Storm Wave Susceptibility
A simple computer model capable of describing potential storm wave inundation and damage along Florida's sandy beaches is described from first principles. Model STORMWAVE...
Measurement and Use of Shear Wave Velocity for Evaluating Dynamic Soil Properties
Geotechnical engineers have recognized in the past decade that shear wave velocity is a basic soil property and have begun to use it to characterize sites for many uses. Most notable has...
Floating Bridge for 100 Year Storm
In 1979 the west half of the Hood Canal Floating Bridge, built in 1960, in Seattle broke up and sank during a storm that lasted eight hours with winds of 80 mph and gusts over 100 mph....
Designing for Residual Flooding
Flood control projects should incorporate designs and responses for flooding of the protected areas due to exceedance, overtopping, or failure of the features. Design strategies for levees,...
Open Channel Flowrate Measurement Using Multipath Acoustic Flowmeters
Recent acoustic flowmeter developments have improved the applicability and accuracy of the multipath acoustic measurement technique. Accuracy, hardware cost and calibration cost can be...
Numerical Models for Two-Dimensional Surface Runoff
Numerical models for surface runoff in watersheds having two-dimensional or horizontally varying topography are presented. Two finite element methodologies, a standard Galerkin and a streamline...
Response of Floating Structures in a Directional Sea
A finite element numerical model is presented to predict the behavior of long floating structures in a multi-directional sea. A follow up numerical model analyzes an important but mostly...
Embankment Overtopping Tests to Evaluate Damage
The paper reports on studies of embankments 6 ft high, 10 to 22 ft in crest width, and 3 ft in length, with slope varying from 2:1 to 4:1. Embankment surfaces include pavement, grass,...
Overtopping of Small Dams?An Alternative for Dam Safety
A research effort was initiated in 1983 by the Bureau of Reclamation to gain insight in the development of cost-effective modifications to small embankment dams which would enable them...
