9-Data Base Management for Long Term Ground Water Level Trends, Uttar Pradesh.- Abstract

Abstract

The indiscriminate utilisation of water resource has created many adverse effects on the natural environment, such as water logging problem, development of Reb deposit rendering fortile land into Usar, and depending of water level. The present paper deals with the changes which have taken place in the hydrological regimes of U.P. with the growth of developmental activities in the field of irrigation specially through groundwater. The data base system (D.B.S) composed of Data file and programme file have been utilised to store the water level data and retrieve the same to evaluate the changes in hydrological regime. For the purpose, the available water level data of 3 4 points, well spread over the 50 districts of U.P., for the period 1981-90 have been subjected to time series analysis to assess the effect of recharge and discharge conditions. The water level trend for pre and post monsoon seasons have been analysed over the period 1981-90 and corresponding changes with respect to 1981 situation have been worked out. The trend analysis have been done by simple linear regression of water level data with respect to time.
