Comparison of Worst-Case and Probabilistic Approaches to Ocean Outfall Mixing Zone Analysis
Two approaches have been used for ocean outfall mixing zone analysis: worst-case approach and probabilistic approach. This paper discusses some advantages and disadvantages of the worst-case...

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...

Wetland Restoration in Southern North Sea Coastal Areas: The Experience of Britain and The Netherlands
Over the past 500 years, extensive reclamation of tidal wetland areas in the lowlands surrounding the Southern North Sea has taken place. In the Netherlands, reclamation has been an essential...

Two- and Three-Dimensional Hydrodynamic Modeling of the Salton Sea, California
The Salton Sea, the largest surface water body in California, faces a myriad of problems related to rapidly changing water levels, rising salinity, accelerated eutrophication, fish kills,...

Propeller Wash Induced Erosion at Quay Walls
The characteristics are examined of the sea bed erosion produced by the scouring action of a ship's propeller wash acting against a quay wall. The rate of development of erosion...

Near Field Modeling
Results of near field modeling of the wastefield formed by the Sand Island, Honolulu, ocean sewage outfall are presented. Over 20,000 simulations were run with the mathematical model RSB...

Application of a Three-Dimensional Model to Assess Seawater Intrusion in the South San Diego Embayment
The San Diego Formation is a Pliocene through Quaternary age aquifer occupying the southwestern-most part of San Diego County. Though the formation is widespread, thicknesses of up to...

Strategies for Operation of Orange County Water District Talbert Seawater Intrusion Barrier, California
Heavy groundwater production in the area of coastal Orange County accounts for large seasonal fluctuations in water levels that can cause groundwater gradients to reverse seasonally. The...

Floodplain Management in Los Angeles County
Los Angeles is located in a geologically young area of the western United States. It is characterized by highly erodible, steep mountains and flat alluvial plains. Located in a semi-arid...

Use of ??8O and ?D to Define Seawater Intrusion
On the basis of previous studies, more than 60 km? of upper aquifer system underlying the Oxnard Plain was believed to be intruded by seawater. Recent work has shown that there are sources...

Economic Impact of Managing Sea Water Intrusion
Sea water intrusion into a coastal aquifer may result from continued over extraction of the aquifer. In many coastal communities, sea water intrusion has led to artificial recharge programs...
