认为河流袭夺是判断地貌演进，即临城期(第四纪)溯源侵蚀与仰平期剥夷面解体破碎的时空标尺，并据此探讨了临城期河流溯源侵蚀的时空格局。 - This kind of instability bulk movement is induced by wave cyclic loading , as a result the slope of bottom bed decrease , water depth increase , and instability bulk movement has the character of subregion , regularity and head erosion , thus it will influence evolvement of region of interest landform , and change flow field and bottom stratum condition continually , so will lead to dynamic influence on structure foundation soil
这种不稳定块体运动由波浪循环荷载诱发，其结果使底床整体坡度减缓，水深加大，而且不稳定的块体运动具有小区域、多发性和溯源侵蚀的特点，将继续影响着海域以后的水深地形的发展演化，并不断改变着该区的流场与底床地层条件，对构筑物地基土的稳定性产生着动态的影响。 - There are four characteristics of the evolution of tidal creek as follows : ( 1 ) in the initial stages , tidal creek develops by continuous eroding trace to the source and depriving of the top of other tidal creeks . ( 2 ) the transverse moving of tidal creek occur mostly in the lower part , the middle part and the outlet take second place , and the upper part is more stability . ( 3 ) the different level branches of tidal creek transform into each other in the whole evolution course
潮沟的演变具有以下特点： ( 1 )潮沟在形成初期，不断进行溯源侵蚀和袭夺以扩大集水面积而发展壮大， ( 2 )潮沟的侧向移动主要发生在潮沟的下段，中段和口门次之，上段最为稳定( 3 )不同级别的支潮沟之间处在不断地相互转化过程之中。
