PREDICTION OF WATER DEFICIT BY PROBABILITY MODELS FOR COIMBATORE REGION, INDIA

V. Malathi

Abstract

Maximum daily rainfall is important for economical planning and designing of small and medium hydraulic structure. Maximum weekly water deficit of different return periods is important in crop planning in rainfed areas to apply supplementary irrigations or to predict the drought in terms of water deficit. There is no widely accepted procedure to predict the weekly water deficit. Hydrological frequency analysis has an application for predicting the future events on probability basis. An attempt has been made in this analysis to estimate the weekly water deficit values for various return periods for Coimbatore district by four distributions and to select the best one.
