Land And Water Resource Evaluation, In Karanja Vagu Watershed.

      Аннотация: The present work envisages to assess the soil and groundwater resources of the following villages Krishnapur, Machnur, Bardipur, Potpalli, Algol, Didgi, Kottur, Yalgud, Nayalkal, Malkalaphad, Ganjoti, Hasalli, Rejantal, Mirzapur, Gangwar, Metalkunta, Naimatabad, Hadnur, Rukmapur and Mungi, covering approximately 167 sq.km or 16,700 Ha. The study area in Medak District lies between 17045' and 170 50' of north latitudes and 77030' and 77040' of east longitude falling in survey of India toposheet number 56 G/9 and 56G/10. An integrated approach of Remote Sensing, GIS, and Electrical Resistivity for groundwater potential mapping has been followed along with hydro- and pedo-geochemical studies. The study has helped to identify the problems and potential of the area to generate a water resource database for overall development on a sustainable basis. In this regard the micro watershed scheme has been followed wherein harvesting of water resource judiciously in a smaller hydrological unit has the prime importance. The hydrological analysis process in GIS is one of the effective methods in terms of cost and time in proposing various water harvesting structures.
