Concerning the Bottom Erosion and Frost Heaving on the Section of the Underwater Crossing Route of MGL Across the River Lena
Abstract The uneven nature of the planned-high-altitude positions (PHAP) of the gas pipelines in the floodplain of the river Lena is affected by the hydrological, natural environment, and climatic processes and such permafrost processes as heaving, thawing, and freezing.The effects of hydrodynamic a...
