Praveena Kumara V
Rainfall data of past hundred 30 years of Chithapur taluk, source collected from Central Ground water board. The data revealed that the average rainfall of CGWB report is 1 mm spread over 30 years. Received from south west monsoon (June-September), north east (October-December), summer (March-May) and winter season (January -February) respectively. Rainfall receiving more than 100 mm of rainfall can be expected only at. The water scarcity and groundwater pollution are the major problems faced by the community of the Chithapur taluk. Shortage of rainfall, industrialization, urbanization, use of pesticides and fertilizers in agriculture results in poor quality and quantity of groundwater. The study area Chithapur with an average temperature of about 340c. The successive failure of rains occurred during the year 1972 and 1973, when large numbers of people were affected. We have to adopt necessary methods to conserve the quality and quantity of groundwater. To minimize the problems caused by water scarcity we have to follow certain technological procedures like irrigation, regulated consumption of ground water, sprinkler irrigation, contour farming, crop rotation, rainwater harvesting, recycling of drainage water etc. Rainfall is the most important natural hydrologic event and is a unique phenomenon varying both in space and time, the rainfall distribution is very uneven and it not only varied considerably from place to place but also fluctuates from year to year. The rainfall is one of the most important and governing factor in the planning and operation strategies of any agricultural programmer for any given area. As such, proper and specific information about the rainfall distribution pattern over a period for a particular place is inessential for proper and optimal planning of requisite irrigation system and cropping pattern. Indian subcontinent gets around 75% of annual rainfall during monsoon period, which lasts from June to September i.e. four months. Theme share of conjunctive water-need of the country during entire calendar year is met by the rainfall, which occurs in the monsoon period. There is large variation in distribution of rainfall from year to year. In our country swallowing floods and thirstily droughts at the results of spectacular extremities of the rainfall distribution.
