Abstract

In Tripura, there are many rivers and most of the rivers are almost dry due to high amount of silt carries from higher altitude and deposits as well at river bed. Thus quantitative as well qualitative results of surface water is not the sustainable resource for supplying for the different stakeholder and thus groundwater has the alternative source to meet the demand for the high density population in the state like Tripura. Dhalai Tripura located in the north east state of India has a good amount of coarse sand for groundwater development dependent. A critical study is undertaken to assess the groundwater availability in the sub-surface aquifer using vertical electrical sounding (VES) survey at nineteen locations with a total of thirty eight points spread over the area. The study results depict resistivity values ranging between 30 ohm and 150 ohm are found to be good aquifer zone with the thickness varied between 36 m and 44 m. Thus it concludes VES survey could be an alternative method to assess the groundwater potential at present and future scenario by reducing the overall project cost and also to reduce the chances of failure for making bore well in the same or nearby critical areas for all stakeholders.
