Sudden shifts in the course of a river on a delta may be predicted

Scientists studying deltas show how they may be able to predict where destructive avulsions– where the flow of water through a delta changes its course – may occur. Many river delta systems are drowning because of rising sea levels. This could push avulsions farther upstream placing more and more communities in jeopardy, making an avulsion predicting tool even more vital.

Asymmetrical waves in barred beaches

Natural beaches often present a breaker bar that significantly affect physical phenomena like, for example, wave transformation, wave reflexion, energy dissipation due to breaking and wave reforming into the trough region.
