A PROPOSAL OF STREAM TEMPERATURE MANAGEMENT USING GPV AT THE DOWNSTEAM FROM A DAM RESERVOIR

Abstract

It is very important to predict the influence on the downstream from a dam reservoir by the effluent because of the river environmental protection of the future. In this paper, the stream temperature management system at the downstream from a dam reservoir was proposed. The 1-dimensional numerical model by the MacCormack scheme was used for prediction of the variation of the stream temperature, and the simple formula of the streambed heat transfer was introduced into the heat transfer equation in this model. The validity of the numerical model was shown from the simulated results for the field observation. Moreover, the applicability of the numerical model using the GSM-GPV was examined, and the stream temperature management system using the GPV was proposed.
