Model Analysis on Planning Problem of River Disaster Prevention in Urbanized Area

Abstract

In this study a mathematical planning model is formulated as explorative optimization model, in which flood run-off simulation models is embedded to describe the disaster caused by flood, in order to analyse planning problem on river disaster prevention in urbanized area systematically.
Based on past studies a stage-wised planning process, comprised with “Stage of analysis” and “Stage of integration”, is proposed and the mathematical planning model is used for designing alternatives of disaster prevention facilities at “Stage of integration” of planning process. Parametric analyses utilizing this model would produce effective information for disaster prevention planning in urbanized area.
The applicability of the mathematical planning mod el is evidenced through case study carried out in Ina River basin area.
