A study at Vlugtenburg beach in The Netherlands found that the amount of sand carried by the wind can be influenced more by the amount of sand available on the beach rather than just the strength of the wind. They collected data over 3 days and discovered that the tide affected how much sand was transported, with more sand moving during low tide. The researchers also found that the intertidal zone, where the beach meets the water, is an important source of sand for transport. They compared two models and found that both traditional and new models fit the data equally well.
