Based on the principle of minimum stream power, a new method for designing stable channel is proposed.

基于最小能耗原理，本文提出了一种稳定渠道断面设计的新方法。

At upper flow regime, the total stream power gradually deviate the effective stream power from movable plane bed to existence of sand wave.

在高能态区，从动平整床面到沙浪的出现，总水流功率又逐渐背离有效水流功率。

The results indicated that more intense streambed structure means greater stream power consumption and steeper channel slope when rivers are in dynamic equilibrium.

结果表明，达到动力平衡时，河道中发育的床面结构越强，消耗水流能量越多，从而稳定维持的纵坡降越大，因此在一定程度上决定了河道纵剖面。

But according to the authors of the latest research, 2013 could see a big breakthrough in tidal stream power.

And the Russians said, well all right, if the Iranians want to possess the whole, what's called the nuclear fuel cycle, that is, to have a guaranteed stream of nuclear fuel for power plants, which involves enriching uranium, we'll do it in conjunction with Iran, but in Russia.
