The yellow river-bed evolution a statistical proof of the mountain-river-desert conjecture

When the Yellow River flows through Hetao Plain in Inner Mongolia, north China, it forms a mountain-river-desert system with Yin Mountains on one side and Hobq desert other side. In this system, dense growth of green grass is formed area fronting river mountains at back, however, opposite river, has an inherent trend to lost moisture, which might cause desertification. This study verifies theoretical conjecture by analyzing Riverbed change from 2014 2021. The seven year showed boundary between grassland dessert, was nothing do banks? past earth surfaces.
