Hydrogeology
The State essentially is hilly terrain, comprising of fissured formations with a few inter- montane valleys having Quaternary alluvial fill. The sub-mountainous tract is a part of piedmont alluvial plains, which merges with Indo-Gangetic alluvium towards south west. Kandi belt and the adjoining hill slopes are underlain by boulders, gravels and clay. The unconsolidated sediments, occurring in the inter-montane valleys and in the sub-montane tracts constitute the principal ground water reservoirs.The yield of the tube wells ranges 100 to 120m3/hr in valley fills. The yield of bore wells in hard rock is limited. The quality of ground water is generally good.
