Abstract
There have been many recent reports of flood disasters from around the world.
Many countries attempt to prepare for disaster situations, but one difficulty that
exists in terms of preparing for flooding is that despite the level of flood hazard
that may exist, many people living within river basins are unable to leave their
homes or seek to return to their homes as soon as the immediate danger has
passed.
We distributed a questionnaire concerning flood hazards to residents within
the basin of the Arakawa River in the old-town area of Tokyo, Japan. The
Arakawa River, which drains into Tokyo Bay, was planned in 1911 with the aim
of protecting the citizens of Tokyo from flooding; it was completed in 1930. All
local residents are assigned a specified evacuation area by the local
administrative body.
The questionnaire was given to a random sample of about 1000 people living
along the Arakawa River. The obtained answers make it clear that many people
living along the river are unaware of their designated evacuation area in the case
of flooding. This is an issue that must be dealt with by administrative guidance
and efforts on the part of the residents. Consequently, the local administrative
body must ensure that residents are well informed in terms of hydrological
information and the locations of areas that provide refuge from flooding.
Keywords: flood hazard, attitude survey, Arakawa River, flood, tidal wave,
tsunami.
