The overall shift from lacustrine to fluvial facies is interpreted to reflect a decrease in syndepositional tectonic activity along the border faults of this rift basin a decrease in the accommodation growth associated with decreased fault activity resulted in a shift from a closed hydrologic system characterized by lakes to an open hydrologic system. The amount of river discharge increases down the fluvial system as a result of the addition of runoff from tributary drainage basins and local precipitation however, in the fluvial–marine transition, it is the tidally generated water movements that exert the major control on the magnitude of the water flux this tidal flux, which is termed the “tidal.

Walther's law of facies, or simply walther's law, named after the geologist johannes walther (1860-1937), states that the vertical succession of facies reflects lateral changes in environment conversely, it states that when a depositional environment migrates laterally, sediments of one depositional environment come to lie on top of another.

Facies assemblages on distributive fluvial systems stephanie davidson1, adrian hartley1, gary weissmann2, gary nichols3 the increase in avulsion tendency is important because it reflects threshold changes in the fluvial system’s ability to transport water and sediment efficiently the location and type of avulsion are variable with.
