The Use of an Equivalent Porosity Method to Model Flow in Marshes
Two dimensional modeling of marshes under unsteady flow conditions often involves description of sections that alternately wet and dry. The equivalent porosity method (King and Roig, 1988;...
For Sure Shores
Fighting a long history of beach-destroying structures and man-made inlets, coastal engineers are finding that the answer to beach erosion lies in a deeper understanding of its dynamic...
Partnering with the Enemy
When you think of EPA and a major corporation, you probably envision them squaring off in court over a Superfund site. But these days representatives from the two groups are just as likely...
Out of Control?
Once heroes in a popular battle against villainous despoilers of Mother Earth, to a growing chorus of observers environmental groups, EPA and other regulatory agencies have begun to look...
Wave Forces on Inclined and Vertical Wall Structures
This monograph,
A Second Life for Dredged Material
To ensure safe, navigable waters, rivers and waterways must be dredged. Dredging in the U.S. requires long-term alternatives for placement of more than 300 million cu yds of dredged material...
Physical Model Tests of Dolos Impact Stresses
An on-going experimental study to determine impact stresses and static nesting stresses in instrumented large scale model dolosse is described in this paper. Seven dolosse were instrumented...
Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...
Validation of a Continental-Scale Storm Surge Model for the Coast of Delaware
Coastal structures are designed to provide protection against various forces of nature acting in the coastal zone. Structures such as seawalls are expected to provide onshore protection...
An Experimental and Analytical Study of the Shoreline Response to Non-Parallel Breakwaters in Oblique Waves
REsults of an experimental and analysis study single breakwaters on oblique waves are presented. Three orientations of the breakwaters are studied, those being parallel to the shoreline,...
Wave Run-Up and Reflection on a Permeable Sea Wall
The swash oscillation on a sloping seawall made of step-shaped concrete blocks, waves and water particle velocity in front of the seawall were measured. It was inferred that incident waves...
Wave Transformation and Load Reduction Using a Small Tandem Reef Breakwater ? Physical Model Tests
The performance of several small reef breakwaters, and a tandem breakwater system (consisting of a reef breakwater positioned upwave from a surface-piercing main breakwater), are quantified...
The Evolution of Breakwater Design
The purpose of this paper is to present a view of the evolution of both the rubble mound and vertical faced breakwaters from the earliest design through the Iribarren and Hudson era. Determining...
Coastal Groins and Nearshore Breakwaters
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers No. 6. This book provides guidance for the design and placement...
Trihalomethanes in Chlorinated Sacramento-San Joaquin Delta Drinking Water Simulated with the EPA WTP-THM Model
Trihalomethane (THM) concentrations at a representative water treatment plant simulated with the EPA Water Treatment Plant THM (WTP-THM) model were used to assess potential drinking water...
3D model verification for a groyne and harbor experiment
A discussion of 3D model verification and calibration based on measurements in a flume is carried out for different test cases (groyne, harbor). The measurement data is available for public...
Reconstruction of the West Breakwater at Port Sines, Portugal

New Directions for EPA's High-Level Waste Standards
Recently enacted legislation passed by the 102nd Congress directs a significant change in the Environmental Protection Agency's (EPA) development of standards for spent fuel, high-level...
Status of WIPP Compliance with EPA 40 CFR 191B?December 1992
Before disposing of transuranic radioactive waste at the Waste Isolation Pilot Plant (WIPP), the United States Department of Energy (DOE) must evaluate compliance with long-term regulations...
A Condition Rating System for Rubble Breakwaters and Jetties
This paper describes one aspect of a series of projects which the U.S. Army Corps of Engineering has undertaken in an effort to improve maintenance management of coastal and navigational...
