Geology 101, Fall 2006 Name: Assignment 7: Rivers and groundwater Define/distinguish the following terms: groundwater vs. stream delta vs. estuary tributary vs. distributary suspended load vs. bed load alluvial fan vs. playa levee vs. floodplain channelization vs. revetment (riprap)porosity vs. permeability aquifer vs. aquiclude (aquitard) artesian spring vs. geyser cone of depression vs. saltwater intrusion karst vs. speleothem Draw a map view of a stream from its headwaters to its mouth (you can make the mouth either a delta or an estuary. Include accurately where the stream would be braided (draw several channels), and where the stream would be meandering (draw several meanders). On one of the meanders indicate the cut bank and the point bar.Draw a stream profile (which is sort of a cross-sectional view – no details about the rocks is needed, however) from the headwaters of a stream to its mouth. Indicate the base level, and accurately reproduce the changes in stream gradient in your drawing. Under the profile, label the portion of the stream where erosion would dominate, and the portion where deposition would dominate. Draw what happens to the stream profile when the stream is dammed. Specifically indicate where erosion and deposition due to the dam
