Coastal erosion can be a big problem, but removing a dam can help. By studying a dam removal project, scientists found that adding sediment to the coast can build up beaches. The sediment from the river formed bars along the shoreline, leading to more sand on nearby beaches. This process even straightened out a curved shoreline. This research helps us understand how adding sediment can improve coastlines.
