INFLOW RATE PREDICTING METHOD AND DAM MANAGEMENT CONTROL SYSTEM

PROBLEM TO BE SOLVED: To solve a problem wherein it is essential to correctly obtain the reaching time of water varied according to a flow rate in order to correctly predict an inflow rate into a dam from the flow rate of an upstream point because the reaching time of water from the upper reaches to the lower reaches of the dam varies according to the flow rate at that time. SOLUTION: The discharge rate of the dam has a feature of varying stepwise. A result curve of a discharge rate of an upstream dam and a result curve of an inflow rate of a downstream dam are therefore used to compute the result value of a reaching time of water between both dams. The result value of the reaching time of water according to each flow rate is stored in a table, and the content of this table is updated at any time according to the result values.
