Abstract—The aim is to forecast the damage length of
damaged maritime structures at each coast for each pass of a
typhoon of the equivalent wave energy of a typhoon at a latitude
of 30°N using the so-called equivalent wave energy (EWE)
method, which has been improved. EWE of typhoons is defined
based on the maximum wind speed and the duration of wind
blowing of the typhoon. Using the data on the damage length of
maritime structures by typhoons and the path and the
equivalent wave energy of typhoons, the vulnerability of coastal
regions along the coastline of Japan for 13 groups of typhoon
with different paths is estimated. The improved EWE method
has been upgraded in comparison with EWE method and it will
be used to estimate the damage length of damaged maritime
structures that will occur along the coast at a latitude of 30° N
before a typhoon strikes. The forecasting method reported here
will be used for the purpose of coastal zone management in
disaster prevention works. Further, it provides useful for
information of storm warning and evacuation of residents along
Index Terms—Equivalent wave energy method, damage length, typhoon vulnerability.
