Abstract
The laser measurement data and building form data are processed automatically, and the flood overflow analytic model of the city part is made. An analytic model is made the triangle mesh which can express a building plane form, and an analytic calculation adopts finite elemental method. It considers how much analytic model preparation is reduced with this technique. And, the effectiveness of an analysis and an analytical model is considered by comparing a measurement value and an analytical result of the flood flood of the Fukui Prefecture Asuwa river that occurred in July, 2004.
