Bars tend to be long and narrow (linear) and develop where a current (or waves) promote deposition of granular material, resulting in localized shallowing (shoaling) of the water. Bars can appear in the sea, in a lake, or in a river. They are typically composed of sand, although could be of any granular matter that the moving water has access to and is capable of shifting around (for example, soil, silt, gravel, cobble, shingle, or even boulders). The grain size of the material comprising a bar is related: to the size of the waves or the strength of the currents moving the material, but the availability of material to be worked by waves and currents is also important. sand hom hook shoal patches Geonames:U.BKSU Geonames:U.TNGU Geonames:T.BAR shoals FTT:5 Shoal recurved spit FTT:208 FTT:209 FTT:206 elongated linear
