【 摘 要 】

Long-term samples of meteorological data are periodically necessary to assess the long standing effects of future hydrological changes. The evaluations are repeatedly undertaken using deterministic statistical analyze which requires daily weather data as input. Andhra Pradesh had experienced frequent disasters like cyclones, floods, droughts etc. The frequency and intensity of the hazardous events has been significantly increasing in there cent decades due to climatic changes and global warming. This model is being applied to all the districts of the state to evaluate the results of abnormally low rainfall and to evaluate possible adjustment polices. The final results shows that the lack of rainfall has larger influence on the living society and the major adaptation sustained by irrigation and the ecosystem which illustrates the potential of hydrological modelling for multiple dimensions of water resources. No significant trend has been detected for annual and seasonal precipitation in the entire state, some of the district's annual and monsoon precipitation has decreased, and has increased during post monsoon and winter seasons.
