Generation of sand bars under surface waves

WebSandbars close to the shore can break up into smaller sandbars with crescentic shapes under less energetic wave conditions. This usually occurs in conjunction with the … WebShallow water on the seafloor causes waves to rise up. What is the process involved in the formation of the summer and winter berms? Higher storm energy in the winter moves sand off the beach and stores it in the nearshore. What is the main difference between tidal flats/mud flats and lagoons? Tidal Flats are sometimes dry
