SUMMARY
On the
hazard of river-bank washout at Tân Đức area, Hà Tây Province
In this paper, the authors present the
results of their preliminary study on the hazard of river-bank washout at Tân
Đức area, Ba Vì District, Hà Tây Province, through the study on the history of
dam construction in the Red River at Tân Đức - Minh Nông area, situated on the
Red River left side, and the determination of main factors causing this
phenomenon. This is the process of meandering of the river, the sudden increase
of stream velocity, due to the combination of high water in flood season and the
opening of water-gate of the Hòa Bình Reservoir situated on the Đà River. Basing
on this, the authors set forth the solutions and petitions for coping with this
hazard.
