Abstract
On 18 July 2004, a localized heavy rainfall occurred in the Fukui area, which is located on the Japan-Sea side of the Japan Islands, in conjunction with the intensified Baiu-front. The Fukui heavy rainfall resulted in many disasters, e.g., landslide, debris flow, dyke-break and flood, especially in the Reihoku district of Fukui Prefecture. One of the most damage was caused by water from a broken dyke of Asuwa-river in Fukui city. Moreover, a lot of damage of the field and the house by the flood and the debris flow occurred in the upstream region in the Asuwa-river. This paper discusses the Fukui heavy rainfall from a view point of remote-sensing. Remote-sensing data of Goes 9, MODIS, ASTER, IKONOS and Aerial orthophotograph are used. The movement of the cloud by Goes 9 images is corresponding at the place and the time of the downpour. The height of the cloud at the downpour is examined by using MODIS thermal band data. The false-color images and the NDVI images of ASTER and IKONOS before and after the downpour are compared, and the damage part is detected. The false-color images and the NDVI images of ASTER and IKONOS are useful for the disaster detection of the downpour, because the influence of the plant and muddy water can be used.
