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. Facies modelling of fluvial systems to inform/constrain conceptual flow models associate professor bryce fj kelly connected waters initiative research centre.
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.

Fluvial system lacustrine ostracods, paleoecology upper miocene duero basin sistema fluvial lacustre ostrácodos (dueñas facies), and distal fluvial deposits indicating the end of regression (grijalba-villadiego facies) the alluvial fan and fluvial systems and the shoreline lacustrine position migrate basinward (maximum regressive lacustrine. Suddenly stream flow drops down to zero: material falls out of suspension deltas are modified in shape by waves, tides, and stream forces, but produce same general facies (discussion below assumes delta into water: substitute desert deposits and desert fossils as appropriate for okavango model.

Do we always have deltaic environments where fluvial systems intersect with marine environment i'm studying a stratigraphic section where clastic sediments are up to 400 meters thick i have recognized three depositional environments being alluvial fan, fluvial, and marine in the upper parts of the stratigraphic column where fluvial system. 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.
