Подходы к оценке социально-экономических рисков, вызванных речным паводком

Волчек А. А., Костюк Д. А., Петров Д. О., Шешко Н. Н. Подходы к оценке социально-экономических рисков, вызванных речным паводкомThe issues of forecasting damage caused by flooding of anthropogenically transformed territories in a river floodplain of a plain type are considered based on the case of the floodplain of the Pripyat River. A method of spatial analysis of the level of the territory usage and the depth/duration of flooding is proposed, the results of which are applicable in preparation of maps of the socio-economic risks associated with flooding, and in planning anti-flood measures

Rain surface runoff modeling using cellular automaton

А. А. Волчек, Д. А. Костюк, Д. О. Петров, Н. Н. Шешко. МОДЕЛИРОВАНИЕ ДОЖДЕВОГО СТОКА ПРИ ПОМОЩИ КЛЕТОЧНОГО АВТОМАТАThe numerical solution of a system of two-dimensional shallow water (Saint-Venant) differential equations in partial derivatives for modeling the dynamics of surface runoff using digital elevation models obtained by laser altimetry leads to a significant increase in the computational load on the computer. The article offers a view on reasonable simplifications for the shallow water model, the two-dimensional cellular automaton for the modeling of rain surface runoff is proposed along with adequacy analysis of the calculations performed in their practical application
