The lower delta plain lies within the realm of river-marine interaction and extends landward from the shoreline to the limit of tidal influence. Large areal extent of the lower delta plain is common where tidal range is large and seaward gradients of the river channel and delta are low. Most commonly in this environment, channels become more numerous and often show a [[bifurcation|bifurcating]] or [[anastomosing]] type of plan view pattern. Environments between [[distributary channels]] comprise the largest percentage of the lower delta plain and consist of actively migrating [[tidal channel]]s, [[overbank splay]]s ([[natural levees]]), [[interdistributary bay]]s, [[bay fill]]s ([[crevasse splay]]s), [[marsh]]es, and [[swamp]]s. Deltas having an extremely high tidal range and an arid climate are often characterized by interdistributary evaporite or barren [[salt flat]]s, where intricate networks of [[tidal creek]]s occur and are separated by broad evaporative sequences. From the standpoint of sand-body formation, the major environmental sequence consists of bay-fill deposits, which often form thin clastic wedges stacked one on top of another and separated by interdistributary bay and marsh deposits. The major environmental sequences described consist of bay-fill deposits (interdistributary bay, crevasse splay-natural levee, and marsh) and abandoned distributary-fill deposits.
