  2. Fluvial terrace - Wikipedia

    en.wikipedia.org/wiki/Fluvial_terrace

    Fill terraces sometimes are further subdivided into nested fill terraces and cut terraces. Both fill and strath terraces are, at times, described as being either paired or unpaired terraces based upon the relative elevations of the surface of these terraces. [4] Eroded alluvial fill 60 feet (18 m) thick at Kanab Creek, Kane County, Utah.

  3. Alluvial river - Wikipedia

    en.wikipedia.org/wiki/Alluvial_river

    Terraces are sediment storage features that record an alluvial river's past sediment delivery. [3] Many changes in boundary conditions can form terraces in alluvial river systems. [3] The most basic reason for their formation is that the river does not have the transport capacity to move the sediment supplied to it by its watershed. [3]

  4. River terraces (tectonic–climatic interaction) - Wikipedia

    en.wikipedia.org/wiki/River_terraces_(tectonic...

    A river terrace is composed of an abandoned surface, or tread, and the incised surface, or riser. [2] If you can date the age of the terrace tread, one can get an estimate of the age of abandonment of that surface, and the age of incision. A simple calculation of h 1 /t 1 can give the average rate of incision(r i), where h i = height of river ...

  5. Terrace (geology) - Wikipedia

    en.wikipedia.org/wiki/Terrace_(geology)

    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".

  6. Alluvial plain - Wikipedia

    en.wikipedia.org/wiki/Alluvial_plain

    The Glossary of Landform and Geologic Terms, maintained by the United States National Cooperative Soil Survey (NCSS), defines an "alluvial plain" as "a large assemblage of fluvial landforms (braided streams, terraces, etc.) that form a low gradient, regional ramps along the flanks of mountains and extend great distances from their sources (e.g ...

  7. Glossary of landforms - Wikipedia

    en.wikipedia.org/wiki/Glossary_of_landforms

    Fluvial island – Exposed landmass within a river; Fluvial terrace – Elongated terraces that flank the sides of floodplains and river valleys; Gorge – Deep chasm between cliffs; Gully – Landform created by running water and/or mass movement eroding sharply into soil; Levee – Ridge or wall to hold back water

  8. San Juan Creek AVA - Wikipedia

    en.wikipedia.org/wiki/San_Juan_Creek_AVA

    Most of the vineyards within the San Juan Creek viticultural area are planted at elevations of 1,000 to 1,280 feet (300–390 m) on river terraces, small alluvial fans, and across the larger alluvial plain. Although some vineyards are planted on steep slopes with southerly and northerly aspects, the viticultural area's vineyards are generally ...

  9. River rejuvenation - Wikipedia

    en.wikipedia.org/wiki/River_rejuvenation

    As mentioned, when a river rejuvenates, it gains more energy and erodes vertically to meet its new base level. A river terrace is the remains of an old floodplain at a higher elevation than the present one. It typically results from river rejuvenation with further rejuvenation able to form new terraces, resulting in a step like profile around a ...
