The model is verified by use of it in a over 700 kilometer watercourse of yangtze river , numerical results are in good agreement with measured data 在长江干流700多公里河道上洪水演进的计算结果与实测资料符合良好。
Moreover , the study improves the mathematical treatment of abrupt slope and adverse slope in watercourse and adds the automatic detection of original data 研究还涉及到河道中的陡坡和逆坡的数学处理、原始数据的自动检测等。
The results will provide important reference value for the design and construction of the watercourse harness of the ningxia river section of the yellow river 该研究成果对黄河宁夏段河道整治工程设计和施工具有重要参考价值。
Ethiopic scorchings browned the upper slopes of the pastures , but there was still bright green herbage here where the watercourses purled 像埃塞俄比亚的烈日一样灼热的太阳，晒黄了牧场斜坡顶上的青草，不过在流水潺潺的地方依然还是嫩绿的草地。
In 2002 , the department maintained about 3 198 kilometres of watercourses , river channels and drains , from which about 54 600 cubic metres of silt were removed 年内，渠务署保养维修约3198公里长的水道、河道和排水渠，从中挖走沙泥约54600立方米。
The other three watercourses are minor streams in the rural outskirts of tai po : tai po kau stream in tai po kau , and the shan liu and tung tze streams in shuen wan 区内其他三条水道属小型河溪，均位于大埔乡郊：大埔?的大埔?溪船湾的山寮溪及洞梓溪。
Public works projects should not cause damage to or interfere with watercourses as far as practicable , except for the execution of the works 在可行的情况下，公共工程不得破坏或干扰水道。若该等破坏或干扰是进行工程时所必须的，工程倡议者施工单位必须把水道修复妥当；
And jehovah said to moses , say to aaron , stretch out your hand with your staff over the rivers , over the watercourses , and over the pools , and make frogs come up on the land of egypt 5耶和华告诉摩西说，你要对亚伦说，把你手中的杖伸在江、河、池以上，使青蛙上到埃及地来。
