Abstract

The ANN model was developed with MLFBP with sigmoid transferred function. While developing ANN model for different input parameters, three steps were followed as identification of model structures, evaluate the performance and adopting model for forecasting. The ANN models were developed for prediction KR, Percent Na, PI, RSC, SAR and SSP using Neurosolutions. In ANN modeling KR, Percent Na, PI, RSC, SAR and SSP, selection of model parameters are very important i.e. input, output and model structure. In the present study, ANN were used to derive and to develop models for prediction KR, Percent Na, PI, RSC, SAR and SSP as groundwater quality parameters of Khed taluka by using post season values of existing groundwater quality parameters as input variables i.e. Na, Mg, K, CaCO3, HCO3. The post season data of groundwater quality parameters for time period 1999-2014 were selected for analysis. Model performance was assessed by statistical method included r, RMSE, Index of Agreement and MBE. In Khed taluka, 3-2-1 was best for predicting KR values and 4-2-1 model was best suited for prediction of percent Na values. In Khed taluka Taluka, for post monsoon season 4-6-1 model was best suited to predict PI and 4-4-1 was best suited to predict RSC. 3-6-1 was best suited to predict RSC and SSP in Khed taluka for post monsoon season.
