GIS Applications for Water Resources Conservation Through Hydrographic Surveys in Chikarayapuram and Pammal Abandoned Quarries

Abstract

Abstract During the year 2017 the Chennai metropolis was facing a severe drought due to failure of monsoon rainfall and starved even for drinking water. A scientific study has been carried out using geospatial technology and echo sounders for the identified source of water from abandoned quarries towards estimating the quality and quantity. The study has identified the quantity of available water is 26,32,967 m3 from both the quarries and the water quality is suitable for drinking purpose and concluded with the recommendations of collecting the excess water (Floodwater) in Chikarayapuram Quarries, which can hold maximum of 0.55 TMC of water for water starving Chennai City with diversion of overflowing water channels to the abandoned quarries with minimal measures. The water in Quarry No.4, Pammal should be treated with hydrochloric acid and after additional water treatment techniques, the water can be utilized for drinking purposes.
