Abstract：Incised valley is a common erosional landform,which is well-developed in ancient rock records and modern depositional settings. However,various sedimentary filling characteristic and planar morphology of incised valley have been reported in different basins and of different ages. Based on theoretical derivation according to Manning formula,the typical incised valley examples of the Viking Graben in North Sea Basin and previous relevant flume experiment results,it is concluded that the slope gradient,rate and amplitude of base level descending and lithology of underlying formation are the main controls on the pattern of incised valley development. These factors control: (1)sinuosity index and width to depth ratio of the incised valley; (2)Planar developing density and scale of the incised valley;(3)thickness and spatial distribution of shelf delta and shelf margin delta associated with the incised valley. During transgression,sedimentary filling and lithology variation of incised valley are mainly controlled by the mean rate of sea-level rising and sediment supply. Based on differences in sedimentary filling and lithology,filling-type of the incised valley can be classified as sand-rich shelf delta and mud-rich estuary.
