A crevasse splay is a geographical feature which forms when an overloaded stream breaks a natural or artificial levee and deposits sediment on a floodplain. This breach can cause large deposits that spread in a pattern similar to that of a river delta. In other words, coarser sediment is deposited first, close to the breach while finer sediment is carried farther to the edges of the crevasse splay. In cross section, the crevasse splay will result in graded deposits which may look like a Bouma sequence. 3, record 1, English, - crevasse%20splay
