The modelling of a spring-time flood streams on the Vyatka River to the forecast extreme situations

Abstract

There are presented results of modelling of a spring-time flood run evolving on a river floodplain. The model is used to forecast contamination transfer processes during spring floods running on Kirovo-Chepetsk floodplain of Vyatka River. The model verification was made with satellite photoshots of the flood propagation area and with monitoring data for contamination concentrations obtained by ecological services both of Kirovo-Chepetsk chemical plant and of Kirov region's administration. The digital implementation of the model can allow to simulate action of various defensive hydrotechnical structures that might be designed and to evaluate their influence on the redirection of the flood streams.
