The combination of fluvial and marine processes creates a unique facies assemblage and reservoir architecture deltaic sediments are deposited as: channel fills. There are different types of fluvial deposits and reservoirs the two end-member depositional types are braided-river and fluvial-river deposits.

The preserved deposits of fluvial meander belts typically take the form of patchworks of sand-prone bar-form elements bordered by genetically related, muddy channel fills in meander belts.
