Algorithm for the flood inundation zone bondaries for the river network based on water spread over the raster terrain model

Abstract

The calculation algorithm is presented for the river network inundation based on the modeling of the water front spread over the raster terrain model. A specific of its implementation is reviewed related to the data representation model, which allows consistent calculation for the river tributaries. The algorithm of primary approbation carried out on EU flooding data is discussed.
