MODELING FEATURES FORMATION STORM SURGE IN A DYNAMIC SYSTEM WHITE SEA – MOUTH AREA NORTHERN DVINA RIVER
Abstract
This study analyses the application of mathematical modeling for the examination of specific characteristics of the storm surges formation in theDvinaBay. The simulation of storm surges in the White Sea was performed with due consideration of the mouth area of theDvinaRiver. The Surface Modeling System (SMS 11) Aquaveo made it possible to construct an unstructured triangulated mesh for the whole White Sea including two external liquid boundaries: one in the Gorlo at the entrance to the sea and another in thePinegaRivermouth. According to ADCIRC model results features of water circulation in theDvinaRivermouth area were identified. The numerical experiments have for the first time demonstrated the specifics of storm surge distribution in the delta channels and in theDvinaRivermouth. Depending on the wind direction the storm surge has a maximum height either in the river mouth, or in the eastern-most channel.Apart from the level of tides and storm surges the ADCIRC model visualizes the currents speed and directions, while a small-scale mesh allows seeing the structure of the coastal currents in the deltaic channels.
