The present study is aim to determining the efficacy of artificial recharge structures (ARS) & producing a desired result in the Granite terrain of Bundelkhand region in Urban town of Harpalpur and adjoin rural area. Groundwater management with aquifer mapping has been carried out in 4 villages (Harpalpur, Chapran, Marori, Sarsed) by M/s AMAY Environmental Consultancies has prepared groundwater supply side management -Recharge plan based on groundwater management.
The area has a severe drinking problem due to groundwater over exploitation of the water resources. The study was carried out in the Granite terrain of Bundelkhand region Chhatarpur. The drinking water crises was happen every year in a month of December to July in study area.
The elevation in the Harpalpur watershed area ranges between 210 to 243 m amsl. Average annual rainfall is 914 mm. The drainage in the area trends SW-NE which merege in Dhasan river which flow from SE to NW direction. In this region quartz reefs trending in NE-SW and NW-SE direction which is act as a water barrier.
During investigation total 28 wells monitored (13 Dugwell, 2 Dug-cum-borewell and 13 Borewell) in the depth ranges between 11 – 25, 30-90, 90-120 and 120-250 meter. During field investigation it has been observed that Disposition of aquifer in Granite Fracture harpalpur area below Dugwell depth and different depth of bore well. Two types of aquifer work in Harpalpur town Weathered and Fractured Granite and the depth of Aquifer is 6-24 mbgl for Weathered and 24, 71, 152-170 mbgl respectively.
Fifteen geophysical survey (9 Gradient Profile and 6 Vertical Electrical Sounding) to identify the thickness of of weathered and fractured granite and the depth of aquifer zones in and around the Harpalpur town or nearby village which shows a significant characteristics.
The effectiveness of the recharge plan was cost effective with the help of suitable site selection of feasible structure. Total 70 no’s of Artificial Recharge Structures have been planned for construction in the area, out of which roof top rain water harvesting structures were 61 (31274.91 Sqm Rooftop Area). The sloping roof area has also been utilizing for harvesting through dugwell/Shallow tube well. The water harvesting structures have also been constructed at feasible locations.
After planning, Design and Implementation of Ground water structures ie: groundwater taming, Recharge shaft and Sub-surface Dyke at suitable sites impact was analysed on surrounding area as the crop production and the water level of surrounding area increased which was not sufficient for crop during past few years. Satellite data is a very good and reliable source for the monitoring of change in agricultural production as well as changes of Land Use Land Cover in Harpalpur town and its surrounding area. For the current study three different sets of Senital-2 satellite images of 10 m resolution (3 March 2018, 8 March 2019 and 02 March 2020) have been used and analyzed. The data used in this study captured in the End of Rabi Season when most of the crop is ready for the harvesting. The purpose of taking satellite data of rabi end season is just to show that at the end of this season which area shows standing crops rather than fellow land. Post impact assessment results are very impressive that we have enhance the cropping pattern as compare to previous year – 980 ha in 2018, 1245 ha in 2019 and 1420 ha in 2020.
