Various quantitative analyses are required for complex and dynamic nature of water resources systems to manage it properly. Groundwater table fluctuations over time in shallow aquifer systems need to be evaluated for formulating or designing an appropriate groundwater development scheme. This paper demonstrates a methodology for modeling rainfall- runoff and groundwater table fluctuations observed in a shallow unconfined aquifer Gonda District Utter Pradesh. The rainfall recharge contributed to its annual increment in the ground in water reserve which in turn is reflected in the rise of water table during the post monsoon period. | Modeling of rainfall and ground water fluctuation of Gonda district Uttar Pradesh India
