Applied Sediment Transport
There is an increasing need to understand, model, and predict, sediment transport and how it is impacted by dam construction, dam removal, dredging, beach nourishment, and other human and natural activities along the river/sea interface. This understanding of sediment routing from source to sink is necessary in order to remove obsolete or unsafe dams, change dam operations, or implement efforts to restore habitat in streams, rivers, and estuaries at the river/sea interface. The goals of this project are:
The land/sea interface is an important setting both for fundamental science questions and for sediment management. The science is important because of the wide range of active processes and the magnitudes of water and sediment involved. The setting is important because of the large proportion of the US population that lives near the coast. These science and management questions are particularly significant where rivers enter the sea. This interface is a main conduit for sediment and pollutants entering the ocean; it is an important biological setting, particularly in estuaries; it is a main site of our nation's harbors; and many of our large cities are situated where rivers enter the sea. Many of our nation's watersheds, estuaries, and beaches been altered radically by human actions over the past two centuries. Many dams have been constructed, and some have been removed. Other land-use practices have increased or decreased the delivery of water and sediment to the coast. Estuaries and harbors have been polluted and dredged. Such human tinkering with watersheds has created an important need to understand the processes involved, to predict the effects of changes to the coastal watersheds, to answer questions raised by managers and other government agencies. Addressing these questions also provides an opportunity to study some of the largest sediment transport experiments in history. Work in the Applied Sediment Transport Project directly supports the mission of the USGS and other DOI agencies. Some tasks have been mandated by acts of Congress or ordered by the Secretary of Interior. Results from this project have led directly to new fundamental understanding of sediment transport as well as changes in dam operations. Project results have been utilized by other agencies and the Secretary of Interior.
