Sentence examples for fluvial valleys from inspiring English sources

Relict non-glacial surfaces are distinguishable from glacial surfaces by large-scale morphologies, including rounded summits, fluvial valleys, and cryoplanation terraces and pediments, and the presence of tors, blockfields, and/or saprolites.

The narrow zone between the crest line and the drainage divide has been identified as the zone of gorges, where gorges and deeply incised fluvial valleys have been formed within Quaternary sediments by the various north-flowing streams.

Our approach incorporates measurements familiar to the stream restoration community and can be applied throughout the northern Gulf of Mexico coastal plain, a region characterized by low relief fluvial valleys, unconsolidated alluvium and meandering single thread sand bed channels.

The morphology of the island is characterized by a broadly circular shape and steep coastal slopes, cut by deep erosional valleys and extremely irregular plateau with a few major fluvial valleys and several closed (or formerly closed) depressions that correspond to modern phreatomagmatic craters and phonolite volcanic domes.

The stratigraphic architecture and morphological assemblage of the Pleistocene fluvial terraces contained in two contiguous fluvial valleys are used to understand the spatial distribution and the timing of the differential uplift that affected two different geological and geomorphological settings of an active orogen.

These deposits are connected to the configuration of the fluvial valley related to the present Sauce Grande River.

Ancient fluvial valley systems are long recognized as important features in the stratigraphic record, but emerged as a specific focus of attention with publication of first-generation sequence-stratigraphic concepts.

Based on the spatial pattern of modern erosion rates, we predict that if the incised fluvial valley was formed during interglacial periods only, it has formed over the last approximately 400,000 years.

Differentiating the deposits of lateral point bar migration and down-valley translation in the rock record is not possible at the facies scale, and thus translated point bars have not been previously recognized or interpreted in the rock record, despite their prevalence in numerous modern fluvial valley systems.

The gradual transition from glaciated to fluvial valley can be clearly observed.

The canyons are interpreted to have developed from fluvial incised valleys furthest updip on the fault-block and from turbidity-current erosion further downdip.
