STUDY ON VALIDITY OF THE HYDROELECTRIC POWER DAM OPERATION ADOPTED GSM AND THE INFORMATION ABOUT TYPHOONS

Abstract

 In recent years, rainfall forecasting technologies have been advanced remarkably and some forecasts with high accuracy have been applied to dam operations practically.
 In this study, a new proposed weather and flood forecasting method, which combines the efficient formulation of GSM (Japan Meteorological Agency's Global Spectral Model) and the information about typhoons, have been applied to Ikehara and Kazeya hydroelectric power dam at Kumano river basin and evaluated. The results showed that the proposed method had the applicability to the dam operations in terms of the reductions of dam flood discharge.
