WebThe longer the infragravity wave period the more widely spaced the bar(s). Another form of infragravity wave called edge waves also influence the longshore spacing of rip currents and channels ... 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
