Abstract (English):
The Dolgay bay is located on the southern coast of the Barents Sea. The average width of the fjord is 0,65 km, average depth – 40,7 m. Bay water area with water is 5,6 km², the volume of the basin is 0,25 km3. In the Dolgaya bay clearly expressed are no longshore sediment transport. Research in August 2008, maximum turbidity was 6,2 g/m³ in the central part of the bay. In cross-section the design Severnaya TPP turbidity value changed within 1,0–1,5 g/m³ in the upper and bottom horizon. On the input side of the Dolgaya bay and adjacent waters of the Barents Sea were conducted depth echosoundings. By results of measurements established electronic maps with contours and bathymetry of the Dolgaya bay. Evaluate seabed deformation during the past 20 years period in the input of the Dolgaya bay and provides a forecast of their change after construction Severnaya TPP by numerical simulation of spatial distribution of sediment flows before and after construction.

Severnaya tripp
Губа относится к полнооборотным заливам, так как морские воды распространяются до ее вершины за один приливный цикл. Прилив в губе Долгая правильный полусуточный, с максимальной величиной в сизигию 4,0–4,2 м, минимальной – 0,7–0,9 м. Эти параметры остаются практически неизменными по всей протяженности губы. Волновая динамическая активность вод губы Долгая высокая, особенно при штормовых ветрах северных румбов, затишные участки практически отсутствуют.
