( 4 ) the dike breach risk of the south bank is relative higher in wandering reaches. ( 5 ) the dike breach risk of the north bank is higher than the south bank in winding reaches. simultaneously, the evaluation results manifest that the evaluation indexes system established from the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes, can reflect the actual situation of hang river in the lower yellow river more fully

Based on analysis of hang river ' s actuality in the lower yellow river and researches related with evaluation of dike breach risk, it is put forward that the influencing factors of hang river dike beach risk in the lower yellow river should involve 4 aspects, the locomotion of incoming water and sediment load, the regional crustal stability, the evolvement of river regime and the stability of river dikes. the evaluation indexes system of hang river dike breach risk and uniform synthetic model are established from the 4 aspects. with the support of gis technology, the evaluation indexes system and the model of multi - hierarchical fuzzy synthetic judgment are applied to estimating the dike beach risk of hang river in the lower yellow river under different flood conditions

That favorable water environment benefited, not only by the rather large percentage of forest cover with quite strong capacity of water conservation in mountain areas, but also by the comparatively lower gravity of soil erosion in the loess plateau in the middle and lower yellow river basin while numerous lakes and swamps still existed at that time and maintained a huge water storage
