ABSTRACT

This article describes a study approach of winter multi-hazards and assessment of their impact on shores, coastal infrastructure and hydraulic structures in the closed water bodies on an example of the Caspian Sea. The whole approach is divided into four main stages. The first stage is devoted to the analysis of existing criteria for hazardous natural phenomena. The second stage is devoted to the reconstruction (hidcasting) of winter multi-hazards. At the third stage, the classification of winter periods depending on the amount of simultaneous occurrence of adverse or dangerous hydrometeorological phenomena is performed. At the final fourth stage the assessment of surge phenomena and dynamic wave impact on coastal territory is carried out. The approach introduced in this article combines methods and mathematical models proved in the world practice into a single fundamentally new method for studying winter multi-hazards and provides new fundamental results. In the future, it may find practical application for short-term forecasting and early detection of emergencies.
