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.

Modelling the impact of regional uplift and local tectonics on fluvial terrace preservation
Geomorphology, 2014A terrace formation model (TERRACE) combined with a longitudinal river profile model (FLUVER) was used to simulate fluvial terrace formation and preservation in the northwest Iberian lower Miño River basin under the influence of three tectonic conditions; namely regional vertical uplift, local basin subsidence, and localised differential uplift.

Palaeohydrological studies indicate that the use of sedimentary palaeoclimatic indicators in fluvial sediments still requires rigorous calibration of the climatic controls on the formation of those indicators. An explorative attempt is made using a simulation experiment with the FLUVER2 model.

Ultramafic Aridisols on a sequence of fluvial terraces in Baja California
Geoderma Regional, 2019Abstract Practically all arid ultramafic soils in North America are in Baja California. An arid watershed in Baja California was found to have terraces with soil parent materials dominated by serpentinized peridotite. The soils on a sequence of four fluvial surfaces in the watershed were studied in order to trace the path of serpentine soil ...

The impact of river capture on fluvial terraces and bedrock incision
Earth Surface Processes and LandformsAbstractRiver terraces are commonly used to infer climate and tectonic histories. Yet, it is increasingly recognised that other processes, such as river capture, can affect river terrace genesis and incision rates and patterns. In this study, we conduct a field‐based investigation of river terrace sequences along the Kolokithas and Varitis Rivers in ...

An Ipswichian fluvial deposit at Fulbeck, Lincolnshire and the chronology of the Trent terraces
Journal of Quaternary Science, 1988AbstractMammalian fossils recently discovered near Fulbeck in Lincolnshire, include abundant hippopotamus, suggesting an Ipswichian date for the Fulbeck Sand and Gravel (new name). These deposits mark a former course of the River Witham; clasts indicate derivation from outcrops of Jurassic rocks and chalky till to the south and south‐east.

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.

Abstract:The Huang Shui River, a main tributary of the Yellow River, crosses a series of tectonically subsided and uplifted areas that show different patterns of terrace formation. The distribution of fluvial terrace of the Huang Shui River is studied through topographic and sedimentologic terrace mapping.

River terrace development by concurrent fluvial processes and climatic changes
Geomorphology, 1993Abstract Along the Usui River in central Japan, three well-developed terrace levels are observed. Each terrace is subdivided into two segments: a filltop terrace along the upper reach and a strath terrace along the lower one. Three valley fillings with coarse gravel beds in the upper reach correspond to the last three glacial ages.
