Hydrologic Analysis of Leveed Interior Areas
Flood damage reduction projects that include levees or flood walls usually involve special problems associated with isolated interior areas. Storm runoff patterns may be altered and remedial...
A Derived Flood Frequency Distribution for Ungaged Catchments
Flood frequency distribution for ungaged catchments are described in the article. The various parameters that effect the flood frequency distribution are describes. Influence of the climate...
Alternative Designs for Permanent Protection of the San Luis Rey River Aqueduct Crossings
The San Diego County water Authority was organized to provide an imported supply of water to the San Diego region. The sole source of the water to the Authority is Metropolitan Water District...
Utilization of Roadway Crossings as BMP's in Urban Areas
Roadway crossings of natural waterways in the urban setting can be used as Best Management Practices (BMP's) by retrofitting existing outlet structures. Pollutant removal is contingent...
Floodplain Delineation Using TINS
Triangulated Irregular Networks (TINs) are becoming an increasingly common tool for modeling terrain surfaces on the computer. They are formed by the triangulation of scattered xyz data...
Coastal Wetlands of Ghana
The Ghanaian coast is overlain with over 50 lagoons and wetlands, which among others, are important wintering sites for European birds. Types, location and size of the wetlands are inventorised....
Are Landscape Patterns Related to Marsh Loss Processes?
Marsh loss that occurs in Louisiana is seldom associated with shoreline erosion of lakes and bayous; instead, marshes break up internally. Marsh loss is attributed to processes that stress...
Crevasses on the Lower Course of the Mississippi River
Before construction of artificial levees, crevasses were a common event along the Mississippi River. They directed sediment out of the main channel and reduced flood stage down river....
Coastal America: Northeast Coastal Strategy
The Northeast Regional Implementation Team of the national Coastal America effort has focused its efforts on the restoration of constricted tidal marsh systems. The disposal of dredged...
Sedimentation Patterns of a Restored Tidal Wetland
Coyote Slough Lagoon was flooded as part of a local mitigation project in 1986. The design of the restored marsh included peninsulas to break up the local fetch and resulted in the development...
Vertical Erosion on Beaches and the National Flood Insurance Program
During the 25 years that the National Flood Insurance Program (NFIP) has been in existence, there has been an increasing recognition of the contribution of both episodic and long-term...
The National Flood Insurance Program and Coastal Hazards
The year 1993 marks the 25th anniversary of the National Flood Insurance Program (NFIP). This milestone offers an excellent opportunity to assess and discuss the relative effectiveness...
The Flood Threat Response in South Louisiana
The flood threat to the people of Louisiana is ever present. Responses to reducing the flood threat have been relocation, structural and regulatory. All of these responses effect the surrounding...
Coastal Protection in the Past Coastal Zone Management in the Future? Case Study for the Ems?Weser Area, Germany
The mainland along the German North Sea coast is low lying land; parts are sheltered by islands. History of coastal protection started about one thousand years ago; in the 13th century...
Issues and Problems in Controlling the Threats of Erosion Along the Nigerian Coastline
Perhaps the most serious problem facing the almost 50% of the world's population which today occupies the coastal zones around the world, is the issue of global warming and the impending...
The Management of Coastal Lagoons: The Approach of the Venice Safeguard Project
An overall design for the safeguarding of Venice from hydraulic risks and the re-establishment of the enviromental equilibrium of its Lagoon has been completed in 1992. The large number...
Evolution of the Santee/Pee Dee Delta Complex, South Carolina, USA
The Santee/Pee Dee delta is located on the north-central portion of the lower coastal plain physiographic province of south carolina, USA, which is underlain by pleistocene strand plain...
Rain Gage Network Size for Automated Flood Warning Systems
A methodology is presented that establishes a rational framework for estimating the optimum rain gage network size for flash flood warning systems based on network performance and economic...
Smith's Infiltration Equation and Flooding Infiltrometers
Smith's infiltration equation was developed by examining the output from runs of a physically-based numerical model of one-dimensional infiltration. The model simulated application of...
Flash-Flood Forecasting by Using the HEC1F Model
The application of a lumped conceptual model, the well known HEC1F, for flash-flood forecasting and warning to the Venetikos river basin in Northwestern Greece, is presented. The combination...
