The river Hwang-Ho (China) is the most "hardnavigable" river among the largest rivers of the world. Leaving the mountains and flowing into the Great China Lowland the river greatly transforms its function - it is transformed from watercollecting artery into waterdistributing one due to intensive infiltration of the river waters through the zone of the bank earth walls. The capacity of the gigantic accretion lenz of the river deposits is defined here by the difference of the denudation bases levels - the initial level corresponding to the grand-denudation surface of the accumulative cycle and the modern level.
