Short-Term Effects of the Banjul Sewerage and Drainage Project on Faecal Coliform Counts
Assessment of the short-term effects of the Banjul sewerage and drainage project on faecal coliforms (indicator organisms for contamination of pathogens) in the coastal areas. The project...
Coastal and Sand Spit Evolution from 1958 to 1992: Saloum River Mouth (Senegal, West Africa)
From the bathymetric map made in 1958 with the Marine Hydrographical Service in France (Number 6147), the 1976 Landsat imagery, the 1981 SPOT simulations, the 1991 SPOT data and the field...
Shoreline Erosion Along the East Coast of Ghana
Coastal erosion along the east coast of Ghana has been persistent within the Keta area since the beginning of the century and severe in the immediate fringes of the west of the Volta Estuary...
Morphology and Current Dynamic of the Coast of Togo
The Togolese coast, flat and fifty km long, is made of two generations of beach ridges, separated from the sedimentary coastal basin, of the Tertiary age, by a continuous system of lagoons....
Modeling Beach Erosion and Shore Evolution
The objectives of this paper are to review some hydraulic modelling techniques for the evaluation of beach erosion and shoreline evolution due to wave and current action. Both numerical...
Aeolian Sediment Transport Under Offshore Wind Conditions: Implications for Aeolian Sediment Budget Calculations
Field studies of aeolian sediment transport on natural beaches reveal measured transport rates that are lower than those predicted by existing equations developed in arid environments...
Shoreline Management Along the Cohesive Shorelines of the Great Lakes
The primary focus of Shoreline Management Plans (SMPs) is minimizing the risks to life and property due to flood and erosion hazards. Various approaches are utilized to minimize these...
A Wave-Energy Dissipation Structure for Shore Protection and Beach Generation, Recovery, and Stabilization
WAVEBLOCK a steel reinforced concrete modularized structure designed to dissipate the energy of saline and freshwater waves is described. The modularized structure, which weighs upwards...
Holocene Evolution of Deltas on the East Coast of India
Disposition of beach ridges vis-a-vis paleo river courses has helped in recognizing several abandoned delta lobes and reconstructing the stages in the progradation of various deltas on...
Louisiana Cheniers: Clues to Mississippi Delta History
The cheniers of southern Louisiana have map differences, deeding differences, and granulometric differences that distinguish them from swash-built beach ridges and from dune ridges. Instead,...
3D-Simulation of the Twin Lake Tracer Test
The 1983 Twin Lake tracer test was simulated using a three-dimensional finite element model. The model was calibrated comparing calculated and measured piezometric heads as well as vertical...
The Influence of Slope and Surface Roughness on Trapezoidal Free Overfall Characteristics
The brink depth-discharge relationship for trapezoidal free overfalls was investigated including the effects of slope and roughness. The theoretical relationship is based on the momentum...
The Tidal Inlet Characteristics of a Small California Estuary
The inlet channel of the Russian River estuary in Northern California is subject to frequent closure. The formation of a barrier beach across the inlet channel creates ponding of the river...
Plans for a Sensitivity Analysis of Bridge-Scour Computations
Plans for an analysis of the sensitivity of Level 2 bridge-scour computations are described. Cross-section data from 15 bridge sites in Texas are modified to reflect four levels of field...
Computational Hydraulics?The Systems Approach
This paper introduces two modern computational hydraulic computer programs that combine the calculated subcritical and supercritical water surface profiles and pressure gradients in open...
Water Surface Profile Computations?How Many Sections do I Need?
One-dimensional streamflow models, including standard-step models, require a sufficient number of cross sections to satisfy two needs. First, a sufficient number of cross sections must...
Calibration of Manning's Roughness for a River Reach
The Albuquerque Projects Office of the U.S. Bureau of Reclamation collected water surface elevations for measured discharges for the Rio Grande and many of its tributaries to try to obtain...
Visualization and Analysis of Multi-Dimensional Velocity Measurements in Carquinez Strait, California
On 11 March, 12 March, 15 April, and 16 April, 1991 the United States Geological Survey (USGS), Sacramento, CA, employed a Downward Looking Acoustic Doppler Current Profiler (DL-ADCP)...
Modeling Critical Depth in Open Channels
This paper explores multiple critical depths. Reasons behind and characteristics of their occurrence are reviewed. A method to determine multiple critical depths is proposed for use in...
Laboratory Study of the Characteristics of Shallow Open Channel Flow Using Fiber-optic Laser Doppler Velocimetry
An experimental study was proposed to investigate the characteristics of shallow rain-impacted flow using a recirculating flume and an artificial rainfall simulator. The fibre-optic Laser...
