Chronosequence in Almar River Fluvial‐Terrace Soil
Soil Science Society of America Journal, 1994Abstract The aim of this work was to analyze how soils formed fundamentally from the erosion of granites evolve under a subhumid Mediterranean climate as a function of age. Their evolution was evaluated by means of the changes in components and properties, as well as the use of developmental indices.

Fluvial terraces of the lower Susquehanna River
Geomorphology, 1993Abstract Fluvial terraces of the lower Susquehanna River offer a unique opportunity to investigate the late stage geologic and geomorphic evolution of the U.S. Atlantic passive margin. Petrography and elevation distinguish and provide a basis for correlation of two groups of terraces, the upland terraces and lower terraces, through the Piedmont ...

Significance of Terrace Deposits in Fluvial Sequence Stratigraphy
Applied Mechanics and Materials, 2013The terrace deposits in a river valley are key records to the research of fluvial sequence stratigraphy. Terrace deposits and the basal sequence boundary comprise the half-cycle of base level fall, and the fluvial infillings belong to the half-cycle of base level rise.

Cosmogenic dating of fluvial terraces, Fremont River, Utah
Earth and Planetary Science Letters, 1997Absolute dating of river terraces can yield long-term incision rates, clarify the role of climate in setting times of aggradation and incision, and establish the rates of pedogenic processes. While surface exposure dating using cosmogenic 10Be and 26Al would seem to be an ideal dating method, the surfaces are composed of individual clasts, each with ...

The Causes of Fluvial Terraces Inland and Its Implication
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006Terraces in tectonically active mountains and uplands record both tectonic uplift and climatic changes. The author discusses the methods of how to distinguish the role of both tectonic and climatic factors. Fluvial system in inland is a process of reaction between aggradation and incision controlled by tectonic movement or climate changes.

Relict fluvial terraces on the Tsondab Flats, Namibia
Journal of Arid Environments, 1979Within the hyper-arid central dune Namib, the dune-free Tsondab Flats, extending 40 km west from Tsondab Vlei, are characterized by terraced topography incised into a conglomerate-capped red sandstone. The hypothesis is posed that the terraces are fluvial in origin and that they preserve a record of fluvial incision and arid interruption.

Fluvial terraces preserve the history of river incision into bedrock over geologic time scales. In this paper we use terraces and a comparison of terrace longitudinal profiles to stream longitudinal profiles to develop a conceptual model of bedrock fluvial incision in diverse geologic, tectonic, and climatic settings.

Fluvial cut-and-fill terraces record climate oscillations
2020Using a model of long-term fluvial erosion and sediment transport (Yuan et al., 2019, JGR-SE), we demonstrate and quantify a direct, physical explanation for the relationship between climate oscillations and the formation of fluvial cut-and-fill terraces.
