Mathematical model of artificial groundwater recharge

In this paper, four cities in India having different geographical structures, climates, and hydrological components were selected. An area of 500 m² from each city has been studied. A mathematical model with three-dimensional components of hydraulic conductivity, hydraulic head in the aquifer, and other factors was adopted, in which additional components of artificial recharge were added. The model is numerically solved with the help of C++ software, with details provided in the Appendix, and the graphs were plotted to depict the status of the groundwater level after the artificial recharge. It was found that during the study period from 2014 to 2021, the increase in groundwater level in Bhopal was 9 m, for Jaipur was 6 m, for Dehradun was 6.5 m, and for Bangalore was 5 m.
