Improving the quality of navigation and hydrographic support in the Arctic rivers estuarine waterways
Abstract On the rivers of the Arctic region common navigation conditions are characterized by quickly changing water levels, a wide riverbed with narrow and embayed fairways, numerous point and spatial navigation hazards. Spatial navigational hazards represent dangerous isobaths of irregular geometr...
