Hillslope Sediment Supply Limits Alluvial Valley Width
AGU Advances, 2022 River‐valley morphology preserves information on tectonic and climatic conditions that shape landscapes. Observations suggest that river discharge and valley‐wall lithology are the main controls on valley width.

River Terraces of the Upper Nakdong River and Wangpi Stream [PDF]
, 1993 River terrace is the main subject of Quaternary research in the nonglaciated area such as Korean Peninsular. Much information about geomorphological events such as the Quaternary paleoclimate and the crustal movement is recorded in river terraces ...

Journal of Quaternary Science, EarlyView.ABSTRACT Glaciokarst landscapes pose distinctive challenges for cosmogenic dating because meltwater and runoff can be rapidly rerouted into ponors and conduit networks, weakening glacier–river coupling and promoting local sediment storage. We reconstruct glacier retreat and postglacial stabilization on the Snežnik Plateau (SW Slovenia) using in situ ...

Characteristics and Evolutions of Fluvial Geomorphology in Foreland of the Kuitun River Valley
Shuitu baochi yanjiu, 2005 Based on field survey, the forms, structures and ages of fluvial terraces and alluvial fans of the Kuitun River, as well the evolution processes were studied, and the impacts of neotectonic movements on fluvial geomorphology are discussed in the northern

Dating the Tejo river lower terraces in the Ródão area (Portugal) to assess the role of tectonics and uplift [PDF]
, 2008 The Tejo river is one of the major drainages in Iberian Peninsula; it is a long-lived system (ca. 3.4 Ma) and provides an archive of long-term landscape development and environmental change controlled by tectonics, climate and eustasy.

Journal of Quaternary Science, EarlyView.ABSTRACT Subfossil insect communities from the Quartz Creek site provide a detailed record of both Late Pleistocene steppe–tundra and Holocene boreal forest ecosystems in central Yukon Territory, Canada. Fifteen Pleistocene assemblages (marine isotope stages [MIS] 4 to 2) are dominated by steppe–tundra and dry‐tundra taxa, particularly the weevils ...

Geomorphometric analysis of urban fluvial terraces using UAV LiDAR: A case study from the La Silla River, Mexico [PDF]
ISPRS Annals of the Photogrammetry, Remote Sensing and Spatial Information SciencesThis study presents a high-resolution geomorphological analysis of river terraces along the urban corridor of the La Silla River (Monterrey Metropolitan Area, Mexico) using UAV-based LiDAR and photogrammetry, with a DJI Matrice 350 RTK equipped with a ...

Journal of Quaternary Science, EarlyView.ABSTRACT Stable isotope analyses of freshwater mollusc carbonate can record environmental conditions at the time of mineralisation, yet this technique remains underused in British Middle Pleistocene fluvial sequences, despite the abundance of fossil shell material in these deposits.

In vitro and in sacco determination of neutral detergent fibre digestibility of treated cereal straw
JSFA reports, EarlyView.Abstract Background Cereal straw is hardly digestible due to its complex bonds of lignin, cellulose and hemicellulose. That is why chemical treatments, such as with sodium hydroxide, may help to loosen the bonds and thus increase ruminal digestibility. Neutral detergent fibre (NDF) digestibility is a good predictor of feed intake.
