Pedogenesis of Fluvial Terrace Soils Related to Geomorphic Processes in Central Taiwan

open access: yesLand, 2023
Pedogenetic features of the soils could be a proxy for revealing the landform surface processes. Our work first analyzed the particle size distributions and lithological discontinuities (LDs) of the soils in the midstream of the Zoushui River, central ...

Geomorphometric delineation of floodplains and terraces from objectively defined topographic thresholds [PDF]

open access: yesEarth Surface Dynamics, 2017
Floodplain and terrace features can provide information about current and past fluvial processes, including channel response to varying discharge and sediment flux, sediment storage, and the climatic or tectonic history of a catchment.

Fluvial incision and tectonic uplift across the Himalayas of central Nepal [PDF]

open access: yes, 2001
The pattern of fluvial incision across the Himalayas of central Nepal is estimated from the distribution of Holocene and Pleistocene terraces and from the geometry of modern channels along major rivers draining across the range. The terraces provide good

"Two tribes": Handaxe shape variation shows distinct regional cultural groups in southeastern Britain between 424 000 and 374 000 BP

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT This paper examines regional and chronological variations in Acheulean handaxe morphology during Marine Isotope Stage 11 (c. 425–365 ka BP) in Britain. Using a data set of 737 handaxes from 13 securely dated sites in East Anglia and the Thames Valley, we apply three‐dimensional geometric morphometric analysis to examine morphological ...

An ultraviolet–visible spectroscopy system for studying real‐time pressure effects on enzyme activity

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Investigations of hydrostatic pressure effects on microbial enzymatic processing are challenging but critical for understanding element cycling in the world's oceans. In this study, we developed and tested a stainless‐steel pressure cell capable of withstanding up to 110 MPa of hydrostatic pressure (equivalent to ~ 11,000 m depth), featuring ...

Morphostratigraphy of river terraces in the Eger valley (Czechia) focused on the Smrčiny Mountains, the Chebská pánev Basin and the Sokolovská pánev Basin

open access: yesActa Universitatis Carolinae Geographica, 2019
The Eger (Ohře) River terraces originated in varied morphotectonic and climate-morphogenetic conditions that existed during the late Cenozoic evolution of the western part of the Bohemian Massif.

Des diagnostics basés sur le calcul des probabilités en vallée de l’Ariège

open access: yesArchéopages, 2022
The legal statutes of diagnostic test trenches often contain a percentage of surface to be tested, and leaves choice of method to the team in the field. The technique consisting in regular and systematic soundings developed in northern France to respond ...

INCEPTIVE TOPOGRAPHY OF FLUVIAL-DOMINATED RIVER MOUTH TERRACES: EXPERIMENTS

open access: yesDoboku Gakkai Ronbunshu, 2003
河川流が卓越する河口部を対象に模型実験を行い, 河口噴流における流速および浮遊砂濃度の分布構造, 掃流砂および浮遊砂による河口テラスの初期形成機構を明らかにした. また著者らの一部が提案した理論の妥当性を検証した結果, 理論と実験結果には良好な一致が認められ, 浮遊砂が支配的な場合, 噴流軸の両側に堆積が生じることが実験によっても示された. さらに河口テラスからデルタへの発達過程に関する実験を行い, 浮遊砂が支配的な場合, 掃流砂が支配的な場合とは明らかに異なる, 鳥趾状デルタに近い堆積形状へと発達することが示された.

Subsurface Investigations of Cryo‐Hydrogeological Features in a High Arctic Catchment Under Transition

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT In this study, the internal structure and seasonal variations of cryo‐hydrogeological features were investigated in the Fuglebekken catchment, located near the Polish Polar Station Hornsund in Svalbard. Over a few years, rising air temperatures and intensified water circulation have significantly altered the distribution, extent, and state of ...
