2 ) the severe aggradation of the lower weihe river bed is mainly caused by the increasing riverbed elevation at tongguan after the construction of the sanmenxia dam ; 3 ) the main reason leading to the increasing riverbed elevation at tongguan is the unreasonable operation of the sanmenxia reservoir ; 4 ) the rate of the riverbed aggradation at tongguan reach and the lower weihe river reach are speeded by adverse condition of incoming water and sediment recently 然后以实测资料为基础分析研究了三门峡建库前后潼关高程的变化规律以及渭河下游河道的冲淤演变规律,分析研究表明:建库前渭河下游主槽处于动态冲淤平衡状态,滩地处于微淤状态;建库后,渭河下游河道发生严重淤积主要是由于潼关高程的抬升造成的;潼关高程的抬升主要是由于三门峡水库的不合理运用造成的,近期不利的水沙条件加剧了潼关河床的抬升速度和渭河下游的淤积。 | | 10. | Because the yili river belongs to plain broad and shallow moving river , the main channel changes greatly and swings to a large range , which leads to river crooked branching river type and s curved , many fork rivers , the river continent and the river beach in river center , alluvial shoal and beach . the width in some section of the river is up to about 3800m . in flood season it causes serious harm to farmland , factories , residents along two sides 由于伊犁河属于平原游荡性宽浅河流,主槽变化不定,摆动幅度极大,河道多呈弯曲分叉河型和s型弯道、多叉河、河心洲,河心滩和冲击浅滩及边滩,部分河段河床宽度达3800m ,洪水季节对河道两岸的田地,工厂,居民等造成极大的危害,素有“三十年河东,三十年河西”之称。 |
