FLOODING ANALYZER FOR A PLURALITY OF WATER STORAGE PONDS AND ANALYSIS METHOD FOR THE PLURALITY OF WATER STORAGE PONDS

摘要

PROBLEM TO BE SOLVED: To provide the flooding analyzer for the plurality of water storage ponds that enables an analysis of a flooding caused by a chain flooding of the plurality of water storage ponds.;SOLUTION: The flooding analyzer for the plurality of water storage ponds comprises: a lower pond inflow amount computing section 32 for computing an amount of water flowing into a pond based on terrain data acquired by a terrain information input section 12 out of an outflow amounts calculated by an upper pond outflow amount computing section 31; a lower pond storage amount computing section 34 for computing the amount of water stored in a lower pond based on pond reservoir information input from a pond information input section 11 from a pond reservoir inflow amount calculated by the lower pond inflow amount computing section 32; and a lower pond outflow amount computing section 36 for computing a lower pond outflow amount flowing out downstream from the lower pond, wherein the lower pond outflow amount computing section 36 has an arithmetic algorithm before a lower pond flooding and the arithmetic algorithm after the lower pond flooding as an algorithm for computing the lower pond outflow amount, and a water level calculated by a lower pond water level computing section 35 in the lower pond storage amount computing section 34 is changed to an arithmetic algorithm after the lower pond flooding to calculate a lower pond discharge amount when the water level reaches a discharge section depth acquired by the pond information input section 11.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2019,JPO&INPIT
