Introduction

  • The number of typhoons are formed an annual average of twenty eight over the Northwestern Pacific Ocean.

  • There come more or less 9 typhoons invaded into Korea, however, two or three typhoons affected badly or landed in Korea.

  • The strong typhoon usually arrived in August and affected in the order of July and September.

Introduction

  • Young-dong region in the Gangwon province was severely damaged due to consecutive 2 years typhoon "Rusa" in 2002 and typhoon "Maemi" in 2003.

  • Generally, the number of losses of life have been decreased, while economic losses have been increased due to the development of technology.

The purpose of the study

  • Aimed to examine

    • - the frequency,

    • - the magnitude

    • - direct/indirect damages

  • Suggest to mitigate the advert impact of typhoon

  • in the study area

Data

  • Data for grading of characteristics and impacts

    • - precipitation, loss of life, economic loss, social impact

  • Data to define total impacted areal extent

    • - Typhoon track data

Data

  • Study period of typhoon track and the amount of precipitation are from 1974 to 2003.

  • In case of typhoon damage, study period is from 1991 to 2002.

  • For the amount of precipitation, data of the weather station in localized land forecast area is used.

  • Sokcho, Gangneung and Daegwallyeong have existed data of whole study period, Donghae and Taebaek have exist data since 1992 and september 1985 respectively.

Methods

  • Typhoon magnitude generally estimate to considerate central minimum pressure or central maximum wind speed.

  • These definitions show the lowest central minimum pressure and the highest wind speed during the lifetime of typhoon until from the formation to the termination of typhoon.

  • Thus, these definitions lack the regionality.

12/25

Methods

  • It is better to use the amount of precipitation than air pressure because this study is typhoon damage impact assessment of the regional scale.

  • Therefore, this study estimate the magnitude of typhoon invading in the Young-dong region using the amount of daily precipitation observed in five weather stations (Sokcho, Gangneung, Daegwallyeong, Donghae and Taebaek).

The trend and the magnitude of typhoon

  • The total number of typhoons occurring in the Northwestern Pacific Ocean from 1951 to 2004  are 1,444.

  • Among these, 176 events invaded in Korea.

The trend and the magnitude of typhoon

  • The amount of precipitation due to typhoon invading in the Young-dong region has been increasing but it is not significant statistically.

The trend and the magnitude of typhoon

  • Frequencies of the extreme precipitation event due to typhoon have increased.

Frequencies above total precipitation 200mm due to typhoon during 1974-1994 and 1994-2003

The trend and the magnitude of typhoon

Frequencies above total precipitation 400mm due to typhoon during 1974-1999 and 1999-2003

  • Typhoon "Rusa" in 2002 caused the record heavy rain of 422mm in Sokcho, 760mm  in Daegwallyeong and 898mm in Gangneung.

  • Therefore, the frequency and the magnitude of typhoon affecting in Young-dong region have been increasing.

Damage analysis in Young-dong region

  • Gangneung city is damaged the most extremely. 

  • Typhoon "Rusa" is estimated to cause 53 losses of life and 869,565,217$ in economic loss in Gangneung city.

  • Damages in Samcheok city is estimated to be 25 losses of life and 510,869,565$ in economic loss and yangyang-gun is 23 losses of life and 456,521,739$ in economic loss. 

  • This area has not been recovered from the impact of typhoon “Rusa” yet, however, in 2003, typhoon “Maemi” invaded again destructed severely.

Results and suggestions

  • Frequencies, total amount of precipitation and heavy rain due to typhoon invading in Young-dong region have been increasing.

  • Due to the advance of the hazard prevention system, the number of losses of life have decreased but economic losses have increased.

  • Especially, public facilities were damaged the most extremely.

  • Therefore, in order to make preparation for these situations, a hydrological system considering inflow and outflow is required.

23/25

Results and suggestions

  • The Korean Government adjusted construction and structure design criteria level practically due to typhoon "Rusa" in 2002 and "Maemi" in 2003.

Adjusted construction and structure design criteria

  • Central government should greatly enhance construction and structure design criteria level which are consulted with experts from a variety of fields.

24/25

Results and suggestions

  • Rapid recover of government to be not damaged the same next the year is required.

  • In order to mitigate the economic cost and the human loss, strengthening of preparedness activities such as planning, training, exercises & drills, emergency awareness & education and warming are required.
