The Problem of Effective Evacuation of the Population from Floodplains under Threat of Flooding: Algorithmic and Software Support with Shortage of Resources

“…Long-term efforts to create the hydraulic structures complex made it possible to significantly reduce the risk of high water in the Neva River and flooding of St. Petersburg [16]. A separate problem is surge floods, which are typical, for example, for the Kaliningrad region, the Lower Don [17], the Kuban river delta [7], the Black Sea bays [18], etc. The causes of severe floods are due to tsunami [19] and ice jams [20].…”

“…Therefore, the algorithms for organizing the safe evacuation of the population of floodplain territories under the conditions of a fairly accurate forecast of the development of floods are of great practical importance [31,32]. The improvement of high-performance computing technologies provides such forecasting and the development of appropriate algorithms has become possible on the basis of interdisciplinary simulations and solving various high-dimensional optimization problems [17,[33][34][35][36][37][38][39][40].…”

“…Finally, since the most important component of evacuation modeling is a hydrodynamic model for forecasting the hydrological regime of a flooded area, we point out the current results of such computer modeling for various water systems [12,16,17,21,23,33,38,71,72]. Modeling of floods near rivers has shown its effectiveness for constructing cadastral maps of water supply [24,36,73].…”

“…Tsunamis or sea storm surges in estuaries, especially in the presence of wide deltas, are a source of flooding. Hydrodynamic models of such events describe well the dynamics of water level rise [8,17,37,74]. Separately, we single out a series of works devoted to the study of the hydrological regime of the Volga-Akhtuba Floodplain (VAF) during the spring flood, since the VAF is the testing ground for our study [24,25,[75][76][77][78].…”
