Webinar: Hardrock Groundwater Recharge using Check-Dams
In Rajasthan and South Australia.
This webinar profiled a joint India-Australia project focussed on groundwater recharge in hardrock environments of Rajasthan and its relevance to South Australia. Rajasthan is one of the most drought-prone states of India and 91% of the State’s drinking needs and 60% of its irrigation requirements are fulfilled by groundwater. The groundwater is totally dependent on the limited monsoon period but plays an important role in the livelihood of village communities. The webinar will look at the important role played by check dams (weirs) in supplementing groundwater recharge in hardrock catchments. It will consider a 3-year study in which daily water level data were recorded by farmers and validated using mobile phone photographs, assessing its efficacy for widespread application in estimating recharge from check dams. In South Australia, which has areas of similar terrain but less extreme rainfall variability, and generally more brackish groundwater, the opportunities for check dams to increase farm incomes and provide drought resilience will also be discussed.
