==Mouth bars==

Mouth bars form where a distributary channel enters a standing body of water and sediment drops out. A shoaling to emergent sand body grows at the channel mouth. The resulting obstruction can cause the channel to bifurcate at the upstream head of the mouth bar. Mouth bars show an arcuate fan shape in plan view and a wedge-shaped profile in cross section. Reynolds<ref name=Reynolds_1999 /> gave average dimensions for mouth bars of about 3 km (1.8 mi) wide and about 6.5 km (4 mi) long (see [[:file:M91FG123.png|Figure 4]]; Table 3). Relatively straight distributary channels building out into deep water will form more linear deposits known as bar fingers ([[:file:M91FG186.JPG|Figure 5]]).<ref name=Fisk_1961 />
