Abstract
The west part of San'in District suffered severe disasters from slope
failure and flood flows caused by record heavy rainfall, in July 23, l983.
At the Hamada meteorological observatory, for instance, the maximum one-day
and one-hour rainfalls were 331.5 mm and 9l.0 mm, respectively.
After delivering the outline of the meteorological conditions and damages,
this paper discusses the runoff process and flood magnitude in representative
mountain rivers such as the Rivers Hamada, Sufu, Misumi and Masuda applying
the kinematic runoff model, and shows that flood peaks are almost near
to maximum experienced values.
