Abstract
Determining alarm levels of river floods is considered as an
effective non-structural measure to prevent and mitigate the damages of
flood and inundation.Studying scientificand
practical base for identifying and adjusting flood alarm level is the
process of understanding flood characteristics and assessing impacts of
floods on social and economic activities.
In this paper, proposed criteria to delineate water levels
corresponding to flood alarm levels include: (1) flood magnitude; (2)
flood derivation and flood duration; (3) flood risks and damage; (4)
correlation with neighboring stations; (5) flood characteristics and
local characteristics and (6) other criteria (rounded, traditional).The result of water level
corresponding to flood warning for each hydrological station is helpful
for warning and prevention of natural disasters and floods.
