Extreme flooding of the floodplains large lowland rivers poses a danger to population due vastness flooded areas. This requires organization safe evacuation in conditions shortage temporary and transport resources significant differences moments different spatial parts. We consider case vehicles, which entire permanent points is impossible. Therefore, divided into two stages with on routes. Our goal develop method for analyzing minimum resource requirement floodplain territories based mathematical model flood dynamics minimizing number vehicles set schedules. The core approach numerical hydrodynamic shallow water approximation. Modeling hydrological regime real body multi-layer geoinformation territory layers relief, channel structure, social infrastructure. High-performance computing performed GPUs using CUDA. optimization problem variant investment scheduling theory deadlines completing work solved basis heuristic algorithm. use results simulation floods Northern part Volga-Akhtuba plot dependence that ensure population. depend discharge Volga river, start evacuation, localization points. developed algorithm constructs schedules allowable various scenarios. constructed can be used practice vast river valleys.

Abstract The floodplain area in the lower Yellow River plays function of flood detention and undertakes production living functions residents. Because basin is one most serious flooding areas China, seriously threatens safety people’s lives property social stability development area. It significant to carry out inundation dynamic analysis loss assessment River. Taking zonal Jiahetan-Gaocun section as an example, a two-dimensional flow mathematical model established by using MIKE 21. Through numerical simulation routing during operation, effect analysed, evaluation are carried out. results show that maximum absolute error water level calculated measuring station only 0.77 m. So, it reliable use 21 simulate process diversion with peak discharge 4000 m 3 /s 7000 basically reaches submerged after 100 h, 173.72 km 2 323.47 , respectively. Autumn grain, main source income for residents, severely lost shallow depth, so they both floods. Therefore, when opening storage area, important consider their loss. can provide scientific basis rational utilization
