Swarm intelligence for groundwater management optimization
This paper presents some simulation–optimization models for groundwater resources management. These models couple two of the most successful global optimization techniques inspired by swarm intelligence, namely particle swarm optimization (PSO) and ant colony optimization (ACO), with one of the most commonly used groundwater flow simulation code, MODFLOW. The coupled simulation–optimization ...

Mathematical modeling for solute transport in aquifer
Groundwater pollution may occur due to human activities, industrial effluents, cemeteries, mine spoils, etc. This paper deals with one-dimensional mathematical modeling of solute transport in finite aquifers. The governing equation for solute transport by unsteady groundwater flow is solved analytically by the Laplace transform technique. Initially, the aquifer is subjected to the spatially ...

Management and protection of groundwater resources in semi–arid zones: application of hydrochemical methodologies to Essaouira Synclinal Basin, Morocco
The water resources of the Essaouira basin are characteristic of a semi–arid climate. It is a coastal aquifer located on the Atlantic coastline, corresponding to a sedimentary basin with an area of about 200 km². The geological structures delineate a syncline bordered by the Tidzi diapir of Triassic age which outcrops to the E and S. In the Essaouira basin, a multi–aquifer composed of detrital ...

Hydrological investigations and water resources management for wildlife sanctuary in central India
The important hydrological issues in Nauradehi Wildlife Sanctuary (NWLS) are development of water resources, development of flora and fauna, trouble–free water availability for wildlife and retention of soil moisture for maximum forest growth. In the present study, the surface and groundwater resources of the sanctuary were estimated using water balance method. The results show that the sanctuary ...

Comparison between an intrinsic and a specific vulnerability method using a GIS tool: case of the Smar aquifer in Maritime Djeffara (southeastern Tunisia)
The assessment of groundwater vulnerability to pollution has proved to be a useful tool to delimitate zones affected by groundwater contamination. For this reason, development of groundwater vulnerability maps became a useful tool for protecting groundwater resources from pollution. The Smar aquifer belongs to maritime Djeffara (southeastern Tunisia); it is essentially occupied by ...

Rainfall changes blamed for India’s groundwater depletion
Changes in rainfall may be responsible for reducing groundwater storage in India more than withdrawals for agricultural irrigation, according to a recently published analysis. Overextraction has long been thought to be responsible for declines in groundwater, but the researchers found less rainfall to be a more important factor. They believe it’s the result of higher temperatures in the ...

A country case study comparison on groundwater and surface water interaction
Traditionally, managing water resources has focused on surface water or groundwater as if they were separate entities. As development of land and water resources increases, it is apparent that development of either these resources affects the quantity and quality of the other. Nearly all surface water features interact with groundwater. These interactions take many forms. This paper provides an ...
