2D Geo-electrical imaging for shallow depth investigation in Doon Valley Sub-Himalaya, Uttarakhand, India
摘要
A 2D geo-electric profiling was executed close to Rajpur area in Doon Valley Sub-Himalaya, Dehradun, Uttarakhand. Profiling was executed at the site Civil Services Institute (CSI) close to Morvian Institute, Rajpur Road in Dehradun for possible shallow subsurface groundwater aquifer. Two resistivity and IP profiles were carried out to discover the conceivable groundwater zones in this area. It has been discovered that there are two inimitable palaeochannels found in these areas. These two channels act an erosional channel which was before happened to be a little stream. Beneath this, there is thick gravel and coarse sand stores in the close surface which is arranged at a profundity of 0.5–5 m with a thickness of 10 m. This zone goes about as brilliant potential for shallow groundwater pockets. Besides, inside the surroundings of these rock stores, fine to medium sand is likewise present in the vast majority of the zones which also may likewise goes about as potential groundwater resources at a shallow depth. Notwithstanding, this groundwater pockets may not be adequate to address the issues of water in the mid year season and is very much prescribed to search for more profound aquifer in the study area.
