Rivers and Streams

• Schematic diagram of river channel, floodplain and terraces
• Floodplain and terraces -- James R near Wingina, Virginia
• Bankfull stage -- this meandering river is just beginning to leave its banks and spread onto its floodplain
• Indicators of bankfull stage -- New Fork R., Wyoming

• Flow pattern and pattern of deposition in meanders -- schematic diagram
• Velocity distribution in meander bends -- schematic diagram
• Meandering river -- showing floodplain features. Nooksack R. near Everson, Washington
• Meandering river widening its floodplain -- White R., South Dakota, S of Badlands Natl. Monument
• Point bar development -- Flathead R near Kalispell, Montana
• Meander cutoffs and natural levees -- Powder R. near Baker, Oregon
• Braided river at low flow -- White R. draining Mt. Rainier, Washington
• Braided river deposits -- White R, Washington

• Floodmarks -- marks like these let us determine flood depth in remote areas. Shinbuster Cr., CA
• Flooding --  approximately 4-yr flood on the Mad R. View upstream from Hatchery Rd. Bridge, Jan 1995.
• Washed out bridge -- failure of old Hatchery Road Bridge near Blue Lake, CA due to undermining in high flow, 1983 
• Levee -- along right bank of Mad R immediately downstream of Hatchery Rd Bridge. Helps protect the town of Blue Lake, CA.
• Flooding -- aerial photo of great flood of 1993 on Missouri and Mississippi rivers

• River terrace and gravels -- terrace cut across rock (strath terrace) and gravel cover, South Fork Smith R., CA
• River terraces -- several levels of low terraces, Overlap Pass, Switzerland
• River terraces -- terraces along a meandering stream, NW Colorado
• River terraces -- alluvial terraces along a braided stream, Truckee R, Nevada
• River terraces -- low terraces along the Mattole R. E of Honeydew, CA
• River terraces -- high terraces along the Mattole R. E of Honeydew, CA
• River terraces -- vegetation differences on low terraces along the Hoh R., Olympic National. Park, WA
• Incised channel -- channel incised into relatively resistant conglomerates, Fern Cyn., Prairie Cr. Redwoods State Park, CA
• Incised meanders -- deeply incised meanders, goosenecks of the San Juan R., Utah

Stream Deposits

• Channeling in old stream deposits -- Wilson Cyn near Mono Lake
• Modern ripple marks -- on sandbar in Rio Grande R
• Climbing ripples -- indicates very rapid stream deposition. Wilson Cyn near Mono Lake
• Ancient ripple marks in sandstone -- Colorado 

Alluvial Fans

• Alluvial fan
• Badwater alluvial fan
• Fan surface
• Mudflow on alluvial fan
• Alluvial fan surface -- Marble Cr. fan
• Alluvial fan deposits -- roadcut in Marble Cr. fan
• Alluvial fan surfaces of several ages

Deltas

• Small delta in pond
• Small delta showing foreset beds
• Delta building into lake
• Small coastal delta -- West Seattle, Puget Sound
• Skagit R delta -- Puget Sound
• Delta mudflat and estuary deposits -- Skagit R delta
• Copper R delta -- saltmarsh deposits
