The present invention relates to a flooding predicting system comprising: a compound disaster setting unit, which loads compound disaster scenario data and space data; a seawater disaster analyzing unit, which calculates a tide and a storm surge height using an ADCIRC model, and calculates a spectrum of a wave height and a wave period using an unSWAN model to generate seawater prediction information converted to a histogram; a land/marine disaster analyzing unit, which calculates flooding levels depending on tide, tidal wave, and wave overtopping using a FLOW3D model to generate marine inundation prediction information, and calculates flooding levels with respect to tide, tidal wave, wave overtopping, and river and inland flooding using an XP-SWMM model to generate land inundation prediction information; and a flooding prediction unit, which collects the seawater prediction information, the marine inundation prediction information, and the land inundation prediction information to generate real-time flooding prediction information of each typhoon intensity or target sea area. According to the present invention as above, a dynamic flooding simulation is performed by calculating information about the storm surge height and wave due to a typhoon through two-way coupling of the ADCIRC model and the UnSWAN model, a seawater level and a wave overtopping rate are calculated by estimating overflow and wave overtopping depending on a structure shape using the FLOW3D model, and a rainfall runoff and inland inundation simulation is performed depending on a water level and a wave overtopping rate using the XP-SWMM model, thereby having an effect that compound flooding occurrence, which caused by the storm surge height and wave overtopping due to storm, and river flooding and inland inundation due to rainfall, may be predicted. 본 발명은 침수범람 예측 시스템에 관한 것으로서, 복합재난 시나리오 데이터 및 공간 데이터를 로딩하는 복합재난 설정부; ADCIRC모델을 통해 조석 및 푹풍해일고를 산출하고, unSWAN 모델을 통해 파고 및 파랑 주기에 대한 스펙트럼을 산출하여 히스토그램으로 변환한 해수 예측정보를 생성하는 해수재난 분석부; FLOW3D 모델을 통해 조석, 해일 및 월파에 따른 침수범람 정도를 산출하여 해상침수 예측정보를 생성하고, XP-SWMM 모델을 통해 조석, 해일, 월파, 외수 및 내수에 대한 침수범람 정도를 산출하여 육상침수 예측정보를 생성하는 육해상재난 분석부; 및 해수 예측정보, 해상침수 예측정보 및 육상침수 예측정보를 취합하여 태풍강도 또는 대상해역별로 실시간 침수범람 예측정보를 생성하는 침수범람 예측부를 포함한다. 상기와 같은 본 발명에 따르면, ADCIRC 모형 및 UnSWAN 모형의 2way coupling을 통해 태풍에 의한 해일고 및 파랑정보를 산출하여 동적침수범람모의를 수행하고, FLOW3D 모델을 통해 구조물 형상에 따른 월류 및 월파를 산정을 통해 해수위 및 월파량을 산출하며, XP-SWMM 모델을 통해 수위 및 월파량에 따른 강우유출 및 내수침수모의를 수행함으로써, 폭풍에 의한 해일고 및 월파, 강우에 의한 하천범람 및 내수침수에 의한 복합적인 침수범람 발생을 예측이 가능한 효과가 있다.
