If the waves are breaking very close to the beach or the beach front is very steep, the sand gets washed back into the ocean and there is net erosion. The deposition of sand leaves stratification parallel to the slope on the beach. The angle of sand on a beach is always significantly less than the maximum angle of repose because of the constant wave action. As wave strength or sediment supply vary, you can get cross stratification. This is often disrupted by burrowing organisms such as clams and crabs, but can be preserved.
Storm surges wash over the berm and deposit sediment on the landward dipping surface.
They can also erode the berm. Wind commonly reworks this sand to form coastal dunes. These dunes are similar to those in arid environments, but due to the proximity of the ocean, they are commonly more moist, and vegetation is common. The vegetation stabilizes the dunes reducing their migration as well as disrupts stratification in them. California is like this around here.
