Predicting Sediment Loads
Many reservoirs in the U.S. and internationally have experienced unforeseen storage loss when sediment loads exceed those originally predicted during the design stage. This often results...
Failure Modes of Flat Bottom Vertical Storage Tanks
Flat bottom vertical storage tanks are important components in essential nuclear power plant safety systems. Data on the seismic capacity and failure modes of such tanks have been identified,...
Sediment Impediment to Boat Launching at Miller Park, City of Avon Lake, Ohio
In 1987 a boat launching facility was constructed at Miller Park, in the City of Avon Lake, Lorain County, Ohio (Figure 1). There have been problems with sediment buildup ever since it...
Mississippi River Diversions for Marsh Creation
Large scale, uncontrolled sediment diversions from the Mississippi River are proposed by the Corps of Engineers as a means of creating new marsh and reducing the loss of wetlands. These...
A Decision Support System for Dredging the Lower Mississippi River
The paper describes a decision support system proposed to aid short-term scheduling of maintenance dredging activities on the lower Mississippi River for the New Orleans District of the...
Pilot Drywell Study Pierce County, Washington
Subsurface disposal of stormwater runoff is widely utilized in areas with permeable or porous soils, including the Clover/Chambers Creek (CCC) Basin in central Pierce County, Washington....
Evaluation of the Feasibility to Retrofit Stormwater Control Facilities to Improve Pollutant Removal Performance
This paper presents the results of an analysis that was performed to predict the efficiency of removal for suspended sediments in storm runoff under existing conditions and under several...
A Comparison of Two Large Scale NLP Strategies for Determining Optimal Pump Station Controls
To solve the general nonlinear problem which is not simplified using the uniform spatial demand patterns, a two-level hierarchial scheme has been identified. The purpose of this decomposition...
Dynamic Effect of Sediment on Dam Hydrodynamics
The dam-reservoir-foundation interaction problem has been studied by many investigators. A two dimensional model of compressible porous media is employed to analyze the dynamic response...
Measurements of Nutrient and Metal Fluxes from the Sea Floor in the Area Around the Whites Point Sewage Outfall, Los Angeles, California
Studies are underway to determine the influence of sewage outfall-impacted sediment on the exchange of nutrients and trace metals in the coastal marine environment. Utilizing a benthic...
Mixing and Dispersion Processes in the Vicinity of an Ocean Outfall System in Southern California
Ocean wastewater plumes are important for the disposal of municipal wastes in Southern California. These plumes, which are discharged from sanitation systems, can be distinguished in the...
Aerial Videotape Mapping of Coastal Geomorphic Changes
An aerial geomorphic mapping system was developed to examine the spatial and temporal variability in the coastal geomorphology of Louisiana. Between 1984 and 1990 eleven sequential annual...
Long Term Assessment of Beach Nourishment Project Performance
Long-term data on profile response, sediment distribution and wave information have been collected and analyzed for the Indialantic/Melbourne Beach beach nourishment project in order to...
Assessment of the Nearshore Zone at St. Marys Inlet, Florida
St. Marys Inlet connects Cumberland Sound from the Atlantic Ocean and actually forms the coastline border between Georgia and Florida. Drumstick shaped barriers are located to the north...
Management of Sandy Inlets: Coastal and Environmental Engineering Imperatives
Management of sandy tidal inlets is required for maintenance of navigable channels and control of beach erosion. Management elements essentially entail 'resharing'...
Controlling Parameters on Littoral Transport and Coastline Development
An extension to the one-line approach to coastline development modelling is presented in the light of the major parameters influencing the longshore sediment transport processes. The model...
Hydrodynamic Behavior of Cohesive Sediments in Turbulent Flow
To meet both engineering and basic research requirements, a series of experiments on the deposition of cohesive soil were conducted in an annular rotating fiberglass channel-ring system...
Pollution Control Strategies of the Puget Sound Water Quality Management Plan: Puget Sound Water Quality Authority
In 1988 EPA designated Puget Sound as an estuary of national significance under section 320 of the Clean Water Act. Due to its natural beauty, favorable climate, and economic health, the...
Port Layout Optimization for Large Bulk Carriers in a Strong Tidal Currents Site
To provide the sheltering conditions of Ponta da Madeira Terminal (TPM) in Sao Marcos Bay, in Sao Luis, Brasil, two rubble mound groins were designed and constructed according to hydraulic...
The Construction of the Shanghai Port and Its Sea-Entering Channel
The Shanghai Port, the biggest port in China, has not enough passing capacity. In order to solve this problem, some new ports must be built. According to sedimentation, fluvial processes...
