Outbreak of musty odor in reservoirs for drinking water caused serious problems with regard to water-supply such as musty taste of tap water. Control of musty odor is one of the most important tasks in water quality management of reservoirs. This paper describes the novel application of an artificial neural network (ANN) model based on the back-propagation method formulated to predict outbreak of a musty-odorous compound, 2-methylisoborneol (2-MIB), in Watarase Reservoir, which is one of drinking water resources for Tokyo area in Japan. By using ANN model, we constructed the model predicting absolute values of the 2-MIB concentrations in Watarase freshwater reservoir. As the input layer data, ANN model used various data obtained from 1992 to 1997, i.e. meteorological conditions, water qualities, nutrients, phytoplanktons, and operational conditions of Watarase Reservoir. Comparing the absolute values of 2-MIB concentrations calculated by the ANN model with those observed, it should be noted that the timing of outbreak of 2-MIB was well-predicted by the ANN model. Prediction of the absolute values of 3 days after- 2-MIB concentrations resulted in 0.65 of the correlation coefficient, thereby indicating good feasibility of predicting 2-MIB concentrations by the ANN model.

饮用水水库的霉味爆发，对供水造成严重问题，如自来水有霉味。水库霉味控制是水库水质管理的重要内容之一。本文介绍了一种新的应用人工神经网络（ANN）模型的基础上制定的反向传播方法，预测爆发的霉味化合物，2-甲基异戊烯（2-MIB），在渡濑水库，这是一个饮用水资源在日本东京地区。利用人工神经网络模型，建立了渡濑水库2-MIB浓度绝对值的预测模型。人工神经网络模型以渡濑水库1992 ~ 1997年的气象、水质、营养盐、植物生长素、运行条件等资料作为输入层数据。将ANN模型计算的2-MIB浓度的绝对值与观察到的绝对值进行比较，应该注意的是，ANN模型很好地预测了2-MIB爆发的时间。3天后的绝对值的预测-2-MIB浓度的相关系数为0.65，从而表明良好的可行性预测2-MIB浓度的人工神经网络模型。
