Test Research on Protection of Root Rocks of the Bank Using Iron Wire Net in the Lower Reaches of Yellow River;

The results showed: As long as taking reasonable measures,we can guarantee the water inlet of convex bank fetch top layer clear w.

For some small hydropower stations,the water intake has to be arranged on the convex bank given special topographic and geological conditions,and the problem of water diversion and sediment control is on the top priority to be solved.
