QUESTION
Effect of urbanisation on hydrological cycle study: Need data on urban watershed, land cover details, groundwater levels

I am a student currently doing my Masters in Engineering. At present I want to study the effect of urbanization on hydrological cycle in India.
For this study I need the data related to hydrographic records from urban watershed, land cover details, soil properties and groundwater level records. Kindly suggest which authority in India keeps records of all this data. 

From Indian Meteorological Department i can collect the climatic data, but I am concerned about the runoff data and land cover change data.  That is the agricultural land and urban land percentage data. Please let me know the relevant authorities name/names, contact information.
