Abstract

Flood damages were estimated by the flood simulation model and cost-benefit for land use types. Economical value in each land use is obtained from the flood control and the economic research manual (The Ministry of Land, Infrastructure and Transport, 2005) . The results obtained are as follows; 1) the economic damage by flood proportionally increases with increasing return period. 2) the expectation value of mean damage for 100 years return period is about 11 trillion yen per year, and 3) the estimated amount of damage in Niigata prefecture in 2004 is comparatively same with the values estimated by government.
