Each summer when David Muerdter comes to the Oregon Coast, he notices that the beach in front of where he stays has changed from the previous summer. Sometimes it is a little wider, sometimes narrower. The dunes down the beach may be taller, the waves are breaking further out or closer in, the dune grass may be spreading seaward. These summer beaches are much different than during a winter visit several years ago when he found the beach much narrower, an example of the seasonal changes that can occur on beaches. In this talk David will discuss how and why beaches change and why waves are the main agent of those changes. Waves interact with beach sand and modify beaches daily, monthly, and over much longer periods of time. Additionally, he will discuss where the sand in this dynamic beach setting comes from and where it goes.
