河弯

河弯的演变特性的研究既是对弯道水沙运动的规律的探索，同时也是预测河道弯曲摆动的主要依据。

The research of the river bend evolution characteristics is not only to explore water-sediment movement law , but also the main basis to forecast river bend swing .

近10年来，由于石首河弯河势发生调整，原港区淤积不能作业，严重制约了腹地经济发展。

In recent 10 years , due to the change of the river bend and river circumstances , sediment was deposited in the original port area and the port could not be used and thus confined the economic development of the hinterland .

河流形成宽阔的河弯，称之为河曲。

The river forms broad loops , called meanders .

弯道岸线的演化发展不仅与河岸的侵蚀和崩塌有关，也涉及到河岸抗冲能力的问题，这是河弯演变理论的重要组成部分。

The evolution and development of the meandering channels which is related to the erosion and collapse of the river banks and involves the river bank erosion-resisting capacity problem , is an important part of the theory of river bend evolution .

距离我们住的地方1公里半有一条河，弯延曲折流入森林。

We lived about 1 and half miles from a river that winds through the forest .

这是一片苍翠的溪谷之地，树木星罗棋布，他瞥见树木之间有一条河流闪闪生光，这河拐了个弯，向大致是西北方向奔腾而去。

It was t a green valley-land dotted with trees through which he caught the gleam of a river that wound away roughly to the North-West .

结合野外调查资料，对试验数据进行回归分析，建立了最大冲刷深度与主要影响因素（水深、泥沙粒径、河宽、河弯半径）的关系式。

The regression analysis was made for the experiments data with the spot measure data , the formula about maximum scour depth in concave bank with the main effect factors ( flow depth , sediment size , river width , radius of the bend channel ) was gained .
