Design of a Basin-Database based on Satellite Data and National Digital Land Information

Abstract

Concept of river-basin-database is discussed for runoff analysis. Two kinds of satellite data and the national digital land information are utilized. MOS-1 data and the national digital land informtion are rearranged into unified format files to represent a river basin in detail spatially. NOAA-AVHRR data are collected as a time series data to analyse a variation of snow field in spring. The basins of the Kamafusa dam and the Tadami River are selected as test fields.
