Küresel nehir sel tehlikesi haritaları, nehir ağı boyunca su baskınını temsil eden ızgaralı bir veri kümesidir. Bu veri kümesi, yedi farklı sel tekrarlama dönemi (10 yılda 1 ile 500 yılda 1 arasında) için geçerlidir. Yeni haritalar için giriş olarak kullanılan nehir akışı verileri, açık kaynaklı hidrolojik model LISFLOOD kullanılarak üretilirken su baskını simülasyonları, hidrodinamik model LISFLOOD-FP ile gerçekleştirilir. Kapsam, Grönland ve Antarktika ile nehir havzaları 500 km²'den küçük olan adalar hariç tüm dünyayı kapsar.
Hücre değerleri su derinliğini (metre cinsinden) gösterir. Haritalar, nüfusun ve ekonomik varlıkların nehir taşkınlarına maruz kalma durumunu değerlendirmek ve sel riski değerlendirmeleri yapmak için kullanılabilir. Veri kümesi, Copernicus Acil Durum Yönetimi Hizmeti kapsamında oluşturulur.
JRC veri kümeleri, kullanım veya dağıtım konusunda herhangi bir kısıtlama olmaksızın kullanılabilir. Daha fazla bilgi için erişim hakları bölümünü inceleyin.

The input river flow data for the\nnew maps are produced by means of the open-source hydrological model\nLISFLOOD, while inundation simulations are performed with the hydrodynamic\nmodel LISFLOOD-FP. The extent comprises the entire world with the exception\nof Greenland and Antarctica and small islands with river basins smaller than\n500 km\\^2.\n\nCell values indicate water depth (in meters). The maps can be used to assess\nthe exposure of population and economic assets to river floods, and to\nperform flood risk assessments.
