Groundwater Provinces by RL Singh

Image
  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...

Monsoon Climatic Type and Tropical Deciduous Forest Biome

Image
  CLIMATE : Monsoon Climate type BIOME : Tropical Deciduous forest Biome It is  generally found along the eastern margins of subtropical regions  Average annual range of temperature is between 32-40 degree Celsius with mean annual average temperature is 27 degree Celsius. Typically characterized by two phenomena Seasonal reversal of winds Fixed period of rainfall The monsoonal regions are given in the map below : They are a degraded form of tropical rainforest with two canopies of trees.  The forests are more open resulting in penetration of sunrise paving way for growth of grasses and shrubs. Average annual precipitation is between 100cm and 200cm.  The coastal areas receive more precipitation while  the interior areas are generally dry. The heavy rainfall in the region lead to excessive leaching away of the topsoil, resulting in formation of Latosols.  Climatic conditions of the region are highly influenced by the shifting of wind belts.
