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

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. The linear regression model between water table and annual rainfall was derived by Karl parson's method. The coefficient of correlation between rainfall and ground water table was found -0.70. The value of statistical errors of R 2 , ME, RMSE and EC were found to be 0.438, 0.213365 and -0.92173respectively. The fitted models, values of fluctuation determination R 2 was found to be significant close to observed value. It has been found that fluctuation was more as compare the availability. A good correlation was found between seasonal rainfall and change in ground water level. The increment in ground water reserve, correlation between climatic parameter and ground water level showed positive and negative relationship. Highest correlation was found in rainfall and ground water level. The developed equation may be adopted for reasonable estimate of ground water table depth at piezo metric stations based on depth for the effective planning and management of ground water resources of the basin.
