Drought is one the climatic as well as natural disasters common all over the world. Droughts have disastrous impact on the economy and can affect the largest segment of the society. Drought by nature is a result of inter-related parameters. The study is based on the concept that the severity of the drought is a function of rainfall, hydrological and physical aspects of the landscape, leading to meteorological, hydrological and physical drought. In the present study a Geographic Information Systems (GIS)-based tool for drought vulnerability assessment at a microlevel has been developed. Groundwater is an integral part of the environment, and hence cannot be looked upon in isolation. There has been a lack of adequate attention to water conservation, efficiency in water use, water re-use, groundwater recharge, and ecosystem sustainability. In the present study an attempt has been made to unleash the power of GIS as an integrating tool for accurate representation and analysis of groundwater quality data. The study area was chosen mainly to know the groundwater quality in Palakkad district. The power of GIS is used for the preparation of ground water quality index of the study area. The present study aims to identify the drought hazard prone areas of different time period and also predict the drought vulnerable area to the next season using the present data and mathematical models. The drought vulnerable area and water quality index map is used for the public for the better management of water resources and drought management.
