title: A two parameter Weibull distribution method for predicting cations in the ground water of Cauvery delta of Tamilnadu.
abstract: A two parameter Weibull distribution model was applied to evaluate the quality of ground water collected from 50 wells in four regions (CSB, VSB, RCA, NDA) of Thanjavur district. The data of the cations (Ca, Mg, K, Na) and EC were used to predict the ground water quality. The shape (a) and scale (b) along with mean and percentile were zoned. A hybrid approach of the Weibull distribution model was done to estimate the mean. This hybrid approach may be used to predict and forecast the ground water quality. From the study the cationic parameters in the wells were not uniform which may be attributed to contamination either by surface flow or sea water.
