전 세계 하천 홍수 위험 지도는 7가지 다른 홍수 재발 주기(10년에 한 번에서 500년에 한 번)에 대해 하천 네트워크를 따라 침수를 나타내는 그리드 데이터 세트입니다. 새 지도의 입력 하천 흐름 데이터는 오픈소스 수문학 모델 LISFLOOD를 사용하여 생성되며, 침수 시뮬레이션은 수력학 모델 LISFLOOD-FP를 사용하여 실행됩니다. 범위는 그린란드와 남극, 강 유역이 500km^2보다 작은 소규모 섬을 제외한 전 세계를 포함합니다.
셀 값은 수심 (미터)을 나타냅니다. 이 지도는 인구와 경제 자산의 하천 홍수 노출을 평가하고 홍수 위험 평가를 수행하는 데 사용할 수 있습니다. 이 데이터 세트는 Copernicus Emergency Management Service의 일부로 생성됩니다.
