A series of terraces along a river. The oldest terraces (T1) are higher standing than the younger terraces (T3). The present floodplain (T4) will soon become the youngest terrace surface as the river incises. Terraces can be formed in many ways and in several geologic and environmental settings. By studying the size, shape, and age of terraces ...
Nested fill terraces: Nested fill terraces are the result of the valley filling with alluvium, the alluvium being incised, and the valley filling again with material but to a lower level than before. The terrace that results for the second filling is a nested terrace because it has been “nested” into the original alluvium and created a terrace.
Sediments underlying fluvial terrace exposed in cutbanks along the Manú River, Peru. In geology, a terrace is a step-like landform. A terrace consists of a flat or gently sloping geomorphic surface, called a tread, that is typically bounded on one side by a steeper ascending slope, which is called a "riser" or "scarp". The tread and the ...
Baymouth bar – low and narrow strip of alluvial land made from sand or pebbles; Beach – Area of loose particles at the edge of the sea or other body of water; Raised beach – Emergent coastal landform; Beach cusps – Shoreline formations made up of various grades of sediment in an arc pattern
Alluvium and adjacent constituents Alluvium deposits in the Gamtoos Valley in South Africa An alluvial plain in Red Rock Canyon State Park (California) Alluvial river deposits in the Amazon basin, near Autazes, AM, Brazil. The seasonal deposits are extremely fertile and crucial to subsistence farming in the Amazon Basin along the river banks.

A Camissonia resembling either of the two species on serpentine stream terraces outside of serpentine masses or mixed alluvium stream terraces could be either C. contorta or C. benitensis. [3] C. strigulosa is the common Camissonia species found growing on nonserpentine alluvial stream and river deposits within the range of C. benitensis.
Floodplain (centre) within the alluvial plain of the Waimakariri River, New Zealand (part of the Canterbury Plains). A small, incised alluvial plain from Red Rock Canyon State Park (California) . An alluvial plain is a plain (an essentially flat landform ) created by the deposition of sediment over a long period by one or more rivers coming ...
