Anthropogenic Activities Affecting Sediment Load Balance Along the West African Coastline
The west African coastline stretches from Senegal in the west-to Cameroon in the east. This coastline had naturally over time received most of its sediments through the numerous rivers...
Factors Responsible for Varying Granulometric Characteristics of Sediments from the Western Nigeria Coastline
The western Nigeria coastline stretches from Badagry in the west (Longitude 5?00'00E), covering a distance of about 275km. Two major geomorphic coastal units are recognized along this...
Recent Bentthic Foraminifera as a Sedimentation Tool in the Nigerian Coastal Environment
The ratio between the living and total populations of benthic foraminifera has been shown to be useful in determining relative rates of sedimentation in paralic and marine environments....
Trace Metal Distribution in the Sediments of the Bight of Bonny, South Eastern Nigeria
Coastal sediments are important hosts for pollutant trace metals. The concentration and distributions of heavy metals depend on factors such as grain size of sediments, availability and...
The Ivorian Coastal Zone: Morphology and Sedimentary Processes?Examples from Grand-Lahou and Abidjan
The Ivorian coastal zone is composed of three main morphological units. The South west coast stretching from Tabou to Sassandra is composed of successions of rocky capes separated by narrow...
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....
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...
The Saint Lawrence River System, Atlantic Coast of Qu?bec
At the 1:250,000 scale, Quebec has 13 773 km of coasts, 6 772 km of which belong solely to the Saint Lawrence River System. This system can be divided into six portions: river, limnetic...
The Magdalen Islands, Gulf of Saint Lawrence
The Magdalen Islands constitute the largest barrier-island system in the Gulf of Saint Lawrence. They represent 435 km of coasts at the 1:50 000 scale, two-thirds of which are sandy and...
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...
The Changjiang (Yangtze) River Delta: A Review
The Changjiang river delta is the best studied one in China in terms of hydrology, sedimentology and evolution history. The construction of Pudong New Area in Shanghai in the 1990s has...
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...
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,...
Humid Tropical Zone Deltas, Their Potential and Limitations for Development: Examples from Java, Indonesia
Monsoonal rivers on Java are responsible for the rapid growth and development of river deltas along the north coast of the island. The climatic and local environmental conditions in these...
The Fraser River Delta, British Columbia: Architecture, Geological Dynamics and Human Impact
The Fraser river delta is the largest delta in western Canada. It is an important coastal ecosystem and an area of explosive urban and industrial growth lying within the most seismically...
Nonpoint Source Pollution Model for Agricultural and Rural Watersheds
A dynamic hydrologic and nonpoint source pollution simulation model for agricultural and rural watersheds; capable of simulating rainfall-runoff, soil erosion, sediment transport, mixing...
Numerical Estimation of Macrodispersivities in Heterogeneous Self-similar Aquifers
Numerical simulations of contaminant transport in a stratified aquifer characterized by a self-similar distribution of hydraulic conductivity were performed. Macrodispersivities were calculated...
Simulation of the Propagation of Conserevative Contamination
The hydrodynamic model of the pollutant transport in water bodies was developed and adopted for Volga water supply system of Moscow, which includes five reservoirs and a channel. The model...
A Two-Dimensional Flow and Hydrogeochemical Transport Model
A two-dimensional flow and hydrogeochemical transport model is designed for estimating the movement and attenuation of chemicals after they are released into subsurface systems. This model...
Investigation of Chloroform Plumes in a Porous Media
A sand box model was used in the laboratory to study the development and stability of the contaminant plume with respect to space and time. Steady, uniform flow velocities were established...
