Abstract

In mountainous basins, SNOW WATER EQUIVALENT is usually used to evaluate water resources related to snow. In this research, based on the observed data, the snow depth and its water equivalent was studied through application of NON-LINEAR REGRESSION, ARTIFICIAL NEURAL NETWORK as well as optimization of network's parameters with GENETIC ALGORITHM. To this end, the estimated values by ARTIFICIAL NEURAL NETWORK, neural network-genetic algorithm combined method and regression method were compared with the observed data. The field measurement were carried out in the Samsami basin in February 2006. Correlation coefficient (r) mean square error (MSE) and mean absolute error (MAE) were used to evaluate efficiency of the various models of ARTIFICIAL NEURAL NETWORKs and nonlinear regression models. The results showed that ARTIFICIAL NEURAL NETWORK and GENETIC ALGORITHM combined methods were suitable to estimate SNOW WATER EQUIVALENT. In general, among the methods used, neural network-genetic algorithm combined method presented the best result (r=0.84, MSE=0.041 and MAE=0.051). Of the parameters considered, elevation from sea level is the most important and effective to estimate SNOW WATER EQUIVALENT.
