Abstract
A collaborative field observation project, named the Biwako Project, was built up in 1989 and has been developed and proceeded by a Japanese group for investigating the hydrological cycle near the land surface, which is composed of tens of members from more than twenty universtities and institutions. The original research fields of the members are rainging from engineering, agriculture to science. The aim of this project, as the title presents, understanding the hydrological cycle in and/or over the Lake Biwa basin together with establishing ways of scaling up and down the hydrological model within the scale of 100km. Specifically, what this project is heading to as goals are;(1) verification of satellite remote sensing;(2) development of algorithms/models describing hydrological processes;(3) understanding the land surface-atomospheric interactions;(4) evaluation of space/time scale effects in the hydrological cycle.
