Spatial Variability of Groundwater Recharge - II. Factors Affecting Variability and Taking Account of it in Estimating Recharge
Spatial variability Groundwater recharge Sri Lanka
2015/8/6
The accompanying paper provided evidence to suggest that spatial variability of groundwater recharge is ‘true’ variability. This paper attempts to determine the major causes of such variability even a...
Spatial Variability of Groundwater Recharge - I. Is it really variable?
Spatial variability Groundwater recharge Sri Lanka
2015/8/6
The spatial variability of recharge is an important consideration in estimating recharge especially as all methods of estimating it are 'point' estimates and in most places recharge varies in space. T...
Land Use/Land Cover Changes and Groundwater Potential Zoning in and around Raniganj coal mining area, Bardhaman District, West Bengal - A GIS and Remote Sensing Approach
Land Use Land Cover Groundwater Zoning
2015/8/6
The Raniganj area has a long history of coal mining starting from 1744. This has resulted in major change in land use pattern and high groundwater abstraction leading to drinking water crisis especial...

Groundwater Port Harcourt City Nigeria
2015/1/9
Of recent, the rapid deterioration of groundwater quality in Port Harcourt, Southern Nigeria due to unregulated exploitation resulting from increasing growth in the oil and gas production activities h...
Groundwater Quality and Vulnerability Mapping of an Unconfined Coastal Aquifer
special index vulnerability index Chenna India
2015/1/9
Groundwater quality mapping is very essential to identify regions where groundwater is suitable for various uses. A study of the vulnerability of groundwater for pollution in a region is required as i...
Groundwater Flow Model and Particle Track Analysis for Selecting Water Quality Monitoring Well Sites, and Soil Sampling Profiles
