Description
-
The Advanced Center for Water Resources Development And Management (ACWADAM) conducted a hydrogeological survey in the Aracode, Coonoor, Ooty, and Sigur regions of the Nilgiri district, Tamil Nadu. The district, part of the Western Ghat mountain range, comprises six blocks with rolling topography and elevations greater than 2000 meters above msl. Keystone Foundation in Kotagiri has been working with tribal communities in the Nilgiri district on water resource management. The survey aimed to develop a broad geological understanding of these locations and understand the complexity of groundwater dynamics. The report compiles field observations pertaining to geology and hydrogeology and integrates static and long-term dynamic groundwater data collected from various springs and wells. Based on these observations and field interactions, recharge areas for selective springs were identified, along with recommendations and a possible way forward. The Nilgiri hills fall under the Southern Granulite Terrain of India, characterized by hard, crystalline metamorphic rocks dominated by charnockites and gneisses.
