In the Luoyang Basin during the Han, Wei, Sui, and Tang dynasties, the flow patterns of the Yi, Luo, Chan, and Jian rivers were closely related to their geological setting. The orientations of these rivers are predominantly determined by the underlying geological fault lines of the basin. The orientations of the Yi and Luo rivers are mainly determined by east-west and northeast-oriented fault lines, with the flow path of the Luo River primarily influenced by the Matun-Yanshi fault and the Yi River influenced by the Yiyang-Yanshi fault. Jian and Chan Rivers share simultaneous spatial similarities and transient transformation similarities, both following city site migrations, turning from being sectioned eastward during Han and Wei dynasties to falling back to the natural southward flow during Sui and Tang dynasties. Luo River exhibited a trend of continual northward transformation during Han, Wei, Sui, and Tang dynasties, while Yi River constantly extends eastward and southward. Over historical periods, the Yi and Luo rivers gradually separated north and south, with their confluence point shifting eastward. Unequal north-south subsidence and a northward tilt of the sedimentary center caused Luo River to migrate northward, while a central bulge and ‘two cut first base’complex fault depression caused Yi River to extend eastward and southward.
