Mitigation Measures for Eroding Muddy Shores
A criterion for the stability of muddy coasts is proposed, accounting for bottom resistance, hydrodynarnic forcing and sediment supply. Although qualitative, this criterion provides a...

A Comparison of Sediment Routing Models
In this paper the authors have compared the performance of coupled linear and non-linear methods of solution from these generic types, in order to assess their suitability for use in optimisation...

Fish Passage Pool Bedding Analysis
Anadromous fish passages, stream dynamics and the artifical channel segmented into a natural stream should fttnction seamlessly. This paper intends to develop reasonable procedures a designer...

Sediment Deposition in the Navigation Approach Channel of Three Gorges Project
In this paper, a comparison is made between the problems of sediment deposition in the navigation approach channel of Gezhouba and Three Gorges Project. The investigation shows that the...

Estimating Sediment Conveyance Capacity and Deposition Potential in Culverts
In watersheds characterized by high sediment production, culverts must be designed to adequately convey both water and sediment without causing excessive backwater upstream of the culvert...

Los Angeles River as a Water Source for a Freshwater Reservoir
Simons, Li & Associates, Inc., performed a study to examine the technical feasibility of a freshwater reservoir in the ocean at the mouth of the Los Angeles River through a conceptual...

Design Modification of Water Supply Intakes in Mountainous Regions
Existing river intakes for several water treatment plants in the mountainous areas of western Venezuela have experienced severe difficulties with deposition of sediment. Excessive sediment...

The Costs and Benefits of Dam Removal on the Elwha River
The Elwha River is located on the Olympic Peninsula in the State of Washington. In the early 1900s two hydroelectric dams were built on the Elwha River. Construction of Glines Canyon and...

Sedimentation Dynamics of Tidal Inlets
Tidal inlets are very dynamic systems subject to continuous morphological changes under the action of tides, waves and transported sediments. Although flow and sediment dynamics are interactive,...

Sediment Erosion Rate in the Baltimore Harbor
In-situ erosion experiments were conducted at four selected sites in the Baltimore harbor in May 1995 using the VIMS Sea Carousel. The measurements showed that the erosion rate decreased...

Adhesion Kinetics of Fuel Oil #6 and Oil-in-Water Emulsions on Marine Sediments under Turbulent Mixing Conditions
Oil spilled in the marine environment is subject to a great variety of physical, chemical and biological processes, which determine its ultimate fate in the aquatic environment. Many of...

Coastal Dynamics '95
Demands to both utilize and preserve the beaches of the world require improved understanding of the underlying dynamics of the coast, as well as better modeling capabilities. To these...

From Sediment to Solid
While closing a 32 acre, storm-water impoundment area contaminated with petroleum waste sediments at an oil refinery, engineers came up with a more-effective treatment plan that saved...

Estuarine and Coastal Modeling
This volume contains the proceedings of the 4th International Conference on Estuarine and Coastal Modeling held in San Diego, California, October 26-28, 1995. The conference included oral...

Modeling Contaminated Sediments
Using a computer model to analyze and predict sediment transport only works when the analyst considers the model's limitations and the physical processes involved, and conducts...

Hong Kong Flies into the Future
Hong Kong's new airport, Chek Lap Kok, is scheduled to open in 1997. That is the year in which China takes over the government of Hong Kong from Great Britain. The airport,...

Dredging Up the Past
Disposal of contaminated dredged materials has become a national problem. The nation's ports and harbors have postponed dredging because of the cost and difficulty in finding...

Advances in the Modelling of Long Span Bridges for Wind Effects
The continued development of longer span suspension and cable-stayed bridges has placed increased demand on both the designers and constructors of these structures for a better understanding...

Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...

Experimental Study on the Strut Type of Cable Net Membrane Structures
In this paper a new type of suspension membrane structure combined with a cable net is proposed, in which the supporting struts are arranged between the membrane surface and the cable...
