Appraisal of groundwater resources in an island condition

Abstract

A group of 36 coral islands is being scattered in the Arabian Sea off the western coast of India. On such islands, groundwater is the only source of fresh water for the islanders. The demand for groundwater is increasing every year due to growing population and urbanization. On the other side the peculiar hydrologic, geologic and geomorphic features restrict the availability of groundwater. Thus a proper understanding of the groundwater condition is important in order to meet this increasing demand and also to formulate future development and management strategies. Detailed hydrogeological, geophysical and hydrochemical studies had been carried out to identify potential fresh groundwater resources and quantify vulnerable parts of Andrott Island, Union Territory of Lakshadweep. Systematic collection and analysis of hydrological, geophysical and hydrochemical data gives an early signal of deterioration in groundwater quality in the peripheral parts of eastern and western coasts of this island and it suggests immediate measures for arresting the deterioration in groundwater quality as well as augmentation for restoration of aquifer in some parts of the island.

Geochemical assessment of ground water in a small tropical coral island of kadamat, union territory of Lakshadweep, India

“…The purpose of the study was to assess hydrogeochemical characteristics of sub-surface water of the Kadamat. The island hydrogeological studies were examined 1 on evaluation of factors influencing the groundwater chemistry in a Small Tropical Island of Malaysia, 2 applied factor analysis tool to the hydrochemical data set of Manukan Island, 3 studied geochemical evolution of groundwater in an alluvial aquifer in the case of El Eulma aquifer, 4 on sustainable water development and suitability of ground water for irrigation purposes in a small coral Island of Minicoy, 5 on major ion chemistry and identification of hydrogeochemical processes of evolution of ground water in a small tropical coral island of Minicoy, 6 on groundwater resources appraisal in the tropical coral island of Kalpeni, 7 used application of multivariate statistical techniques in the assessment of groundwater quality in seawater intrusion area in Bafra Plain, Turkey, 8 carried out assessment of groundwater quality for Veppanthattai taluk, Perambalur district, Tamil Nadu using Remote Sensing and GIS, 9 on fresh water -salt water relation, 10 appraisal of groundwater resources in an island condition and many others. In the present study hydrogeological scenario and geochemical processes of evolution of groundwater in the coral island have been examined.…”

Analysis of electrical resistivity data in resolving the saline and freshwater aquifers in west coast Maharashtra

“…Mondal et al (2009) has envisaged the fact that contaminants play a vital role in both inland and coastal aquifers. These authors further suggest that the electrical resistivity of the aquifer is reduced due to contaminants which reflect as an anomaly.…”
