A coastal scientist’s perspective on dam removal

Figure 3: The river mouth of the Elwha River was transformed by dam removal. While the mud that made it to the coastal zone has largely moved out of the system, much of the sand and gravel deposited right near the river mouth during dam removal, and is still there. It built new beaches, estuary lagoons, and other shallow coastal habitats. The sea-floor was also transformed in patches right near the river mouth. The dots reference locations of photos shown in Fig 4.
