Groundwater Provinces by RL Singh
GROUND WATER PROVINCES : R L SINGH The natural ground water provinces are based on the following parameters : 1. Precipitation : Higher the precipitation, higher the ground water availability. 2. Structure of Rocks : Includes rock structural properties like porosity, permeability etc 3. Slope or Topography : Gentle slopes facilitate higher infiltration. 4. Vegetation : Greater infiltration due to prevention of runoff of waters. On the basis of natural factors of ground water availability, India is divided into 8 provinces by RL Singh. ZONE 1 : Pre-Cambrian Crystalline Province: Regions : Darwar, Aravalli, Rajasthan, Bundelkhand. Consolidated shield rocks preventing water percolation, hence less availability of ground water ZONE 2 : Pre-Cambrian Sedimentary Province: Regions : Mainly constitute the Vindhya and Cuddapah formations Consolidated sedimentary rocks preventing water percolation, hence less availability of ground water ZONE 3 : Gondwana Sedi...
