B) It dropped during the past few centuries and that trend will continue. Building and lengthening of the superaqueous portion of a spit or bar is caused by the transportation of material from the shore toward the distal end of the structure by the swash and backwash when the waves break obliquely on the shore. Waves that arrive in a direction other than obliquely along the spit will halt the growth of the spit, shorten it, or eventually destroy it entirely.[4].

Activities such as logging and farming upstream can increase the sediment load of rivers, which may hurt the intertidal environments around spits by smothering delicate habitats. 1 What is the difference between a spit and a baymouth bar? Definition of bay bar : a bank of sand or of sand and gravel deposited by waves and currents across the mouth of a bay so that the bay is no longer connected or is connected only by a narrow outlet with the main body of water. At this point only, we get net transport of water in wave direction. A spit is a deposition landform found off coasts.

Stump formation: Step 2. Since prehistory humans have chosen certain spit formations as sites for human habitation. The shallow, protected bodies of water behind baymouth bars and barrier islands are lagoons. If the supply is not interrupted, and the spit is not breached by the sea (or, if across an estuary, the river), the spit may become a bar, with both ends joined to land, and form a lagoon behind the bar. For a passing wave, the depth below which the motion of water particles become negligible is equal to Neap tides are produced when the Moon is at right angles to the line connecting the Earth and Sun. Roads or bulkheads built along bluffs can drastically reduce the volume of sediment eroded, so that not enough material is being pushed along to maintain the spit.
