The development in drainage basin of near urban has been producing the quick change of landuse and the danger caused by floodpeak incresease.
For taking a countermeasure to protect the danger, it is necessary to timely obtain the infermations of change of landuse, and take an examination on relationship between the change of landuse and the change of flood runoff charactaristics.
This paper shows a method of classification of landuse which use the vegetation cover rate (V.C.R) as an index, and which V.C.R is calculated by Landsat data, and shows the result of a case study through the drainage basin Iruma River in Saitama Prefecture.
The categorie of classification of landuse are Rice field, Forest, Urban, Mixed area of forest and urban, and Golf links.
