The Water Security Plan for the sustainability of Water Resources of Amini Jalgram, Union Territory of Lakshadweep, South India has been studied. Amini Island is one of the smallest inhabited islands of the Union Territory of Lakshadweep having an area of 2.60 km 2 , where the fragile ground water resource is occurring as lens over marine water. Amini Island is entirely different from that existing in the main land. On the basis of the hydrogeological investigations and other related studies, certain participatory water management programs are to be urgently initiated in the island for the sustainability of water resources of the study area.
The Water Security Plan for the Sustainable Development of Water Resources of Kadamat Jalgram, Union Territory of Lakshadweep, South India has been studied. Kadamat island is the fourth largest of the inhabited islands of the Union Territory of Lakshadweep, with an area of 3.13 km2, where the fragile ground water resource is occurring as lens over marine water. The hydrogeological conditions of Kadamat island is entirely different from that existing in the main land. On the basis of the hydrogeological investigations and other related studies, certain participatory water management programs are to be urgently initiated in the island for the sustainability of water resources of the study area. The aquifers of the Kadamat are organic/coral limestones and sands with depth to the water table ranges between 1.4 and 5.0 mbgl and the ground water occurs under phreatic condition. The phreatic water is exploited by open dug wells and filter point well and depth vary from 1.4-5.0 and 1.8 to 6.0 m bgl respectively. The stage of ground water development in Kadamat is 46.7% and comes under safe category of ground water development. The electrical conductivity (EC) ranges from 500 to 15,000 µS/cm at 25oC. Renovation of open dug wells, filter point wells and tanks/ponds, scientific management/conjunctive use of both surface and sub-surface water, rainwater harvesting structures to be made mandatory, awareness campaign and training programmes to be organized at grass root level on water management as aspects and water budgeting at grass root level, thrust will be given to participatory water ground water management, and an integrated water security plan for the Kadamat are to be prepared and executed.
In Kadamat ground water occurs under phreatic condition and floats as lens over the marine water and the principal aquifers are coral sands and coral limestones. The depth of the wells 1.5-3.8 mbgl and depth to the water table 1.2 to 3.6 mbgl. The ground water is under Na+-SO 4 2type, shallow meteoric percolation types and alkaline (EC variation 435-881 micromhos /cm at 25 o C. The water sample is Ca-HCO 3 Type (recharge type). The hydrochemistry is mainly controlled by e v a p o r a t i o n , partly influenced by waterrock interaction and aquifer m a t e r i a l s. The evaporation process played major role in the evolution of water chemistry. The suitability of ground water in the study area for various purposes is highlighted.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
