PPT-Sediment Deposition and River Structures

FREEING THE ELWHA Deposition of Large Materials Once rivers reach lower gradients their erosional power decreases and their ability to carry sediment downstream also decreases With low flows .

Exelon Application states, “The cumulative impact of the Project to the system is to provide the last site of sediment storage along the Susquehanna River before sediment reaches Chesapeake Bay. This has benefited Chesapeake Bay by providing a means by which the quantity of fine-grained sediment and associated nutrients, sources of water quality impairment, reaching the Bay are reduced.”. Physical Weathering. Weathering. is the breakdown of rock or soil. . Physical . weathering occurs when natural forces, such as wind, running water, and moving ice, physically break up rock and soil into smaller particles. . Geology 103. Depositional environment. Is the term given to the area where the sediment was originally deposited. Must be inferred from the rock identity. Clastic. . depositional environments. Dominated by actions of waves, tides and currents. Lesson 1. Water Erosion. How does Moving Water Cause Erosion?. Erosion is the process in which sediment that has been broken down through weathering is moved.. Agents of Erosion are:. Water. Wind. Glacial (ice). Molly Wood, P.E.. USGS Idaho Water Science Center. Snake River nr . Anatone. , WA. Clearwater River at Spalding, ID. Kootenai River, ID – multiple locations. Boise River near Parma, ID. 6 surrogate gages w/acoustics. Energy. : the ability to do work or cause change.. Kinetic Energy. : energy an object has due to its movement. Abrasion. : wearing away of rock by a grinding action. Load. : the amount of sediment that a river carries.
