Sea-water intrusion into ground-water basins bordering the California coast and inland bays

Effect of strip recharge on sea water intrusion into aquifers

Parametric studies were carried out to analyse the effect on sea water intrusion of freshwater recharge through a finite width strip parallel to the coast. A vertically integrated one-dimensional finite element model was used for this purpose. The studies included the analysis of the effect of location, width, intensity and the period of recharge on sea water-freshwater interface motion. Relati...

Water Quality and Flow into Lagoons of the Eastern Alaska Beaufort Sea Coast

Coupling Surface And Ground Water Processes For Water Resources Simulation In Irrigated Alluvial Basins

Understanding the interaction between soil, vegetation and atmosphere processes and groundwater dynamics is of paramount importance in water resources planning and management in many practical applications. This is the case, for example, of the most important agricultural and industrial area in Italy, the Padana Plain, where intensive exploitation of groundwater for domestic and industrial supp...

Effects of Agronomic and Geologic Factors on Pesticide Movement in Soil : Comparison of Two Ground Water Basins in California

This paper describes the preliminary results of a study conducted by the California Department of Food and Agriculture which compares the soil distribution of herbicides in two ground water basins in the state. In a previous study, residues of several agricultural chemicals were detected in numerous wells in two inland ground water basins, while only one contaminated well was found in two coast...

Impact of coastal land reclamation on ground water level and the sea water interface.

Land reclamation in coastal areas may have a significant effect on local ground water systems. Steady-state analytic solutions based on Dupuit and Ghyben-Herzberg assumptions are derived to evaluate this effect. Two situations are considered, both with ground water flow resulting from precipitation recharge: the coastal aquifer of an extensive landmass and an island. The results show that after...
