Geomorphological problems of the middle reaches of the Tsangpo River, Tibet

Auteur :
DIAN ZHANG, D.

Description :
The middle reaches of the Tsangpo River consist of alternating sections of wide valleys and gorges. The wide valley sections have braided and anastomosing channels, gentle hydraulic gradients, thick alluvial deposits and low terraces. In contrast, the gorge sections exhibit single, straight and deeply entrenched meandering channels with steep hydraulic gradients, bare rock river beds and higher terraces. Several hypotheses have been used to explain these unusual fluvial landforms, but geological, landform and sedimentary analyses along with dating information, suggest that the key could be the active faults across the river valley.
