Detailed Description

Stylized animation showing the shoreline of a wetland that is eroded by waves or currents eating away the sediment along the edge of the wetland. The displaced sediment is then deposited back onto the wetland platform by other waves. When this process happens continually, layers of displaced sediment build up over time, raising the surface of the wetland. This process ultimately leads to both elevation gain and land loss at the same time.
