Fukui Heavy Rainfall on July 18, 2004 gave the great damage to the Fukui City area as well as the mountainous midstream area of the Asuwa River. The major damage in the Fukui urban area is the destruction of the embankment at the left bank of the Asuwa River. Flood water depth and flood level were measured at 146 spots, and overflow depth above the embankment of the Asuwa River was also at 10 points. In addition, flood deposits were sampled and analyzed the grain size at 32 points. The inundation water flowed into the urban area from the collapsed embankment had one main flow along the main prefectural road which extends from east to west, and pooled in the lower area of the dammed-up tributary floor.
