The geomorphology of humanity

Proceedings of the 33rd Romanian Geomorphology Symposium, 2017
For millennia, natural processes such as tectonic uplift, volcanic, climate, erosion, sediment transport and deposition have shaped the Earth surface. The Earth science community also started to consider biota as a geomorphological agent that has a role in shaping the Earth surface, even if at a different scale and magnitude than that of other major ...

Flocculation regulates suspended sediment transport in estuarine fronts

Limnology and Oceanography Letters, EarlyView.
Abstract This study examines suspended sediment transport affected by flocculation settling in a highly stratified tidal estuary. In situ observation recorded two estuarine front passages during strong‐ebb and flood‐slack tides, respectively. The strong‐ebb front enhanced turbulence, increasing sediment concentrations (~ 5 ppm), macrofloc size (~ 300 ...

Deltaic engineering‐induced accumulation hides erosion in response to fluvial sediment decline in the Yangtze submarine shoal

Limnology and Oceanography Letters, EarlyView.
Abstract Worldwide river deltas are impacted by human activities and climatic change, but it has been challenging to quantify their contributions due to nonlinear natural processes and a lack of long‐term geomorphological data. Time‐series bathymetric data were collected at submarine Hengsha Shoal in the Yangtze Delta during 11 repeat surveys over 60 ...

Planetary geomorphology research: FY 1990-1991 [PDF]

Progress in the following research areas is discussed: (1) volatile ice sublimation in a simulated Martian polar environment; (2) a global synthesis of Venusian tectonics; (3) a summary of nearly a decade of field studies of eolian processes in cold ...

Population genomic analyses reveal extensive genomic regions within selective sweeps associated with adaptation and demographic history of a wheat fungal pathogen

New Plant Protection, EarlyView.
Applying population genomics, this study revealed that Pst exhibits slower linkage disequilibrium decay compared to rust fungi with known sexual reproduction, identified extensive hard and soft sweeps linked to Pst adaptation, and demonstrated that crop domestication and breeding programs have significantly influenced pathogen population sizes ...

Andrean examples of mega-geomorphology themes [PDF]

Geomorphic (or physiographic) provinces have been a well known and useful method of regional landform classification for a century. Every earth scientist will recognize a phrase such as Appalachian Plateau or Southern Rocky Mountains as defining a ...

Multi‐scale geophysical imaging of neotectonic fault activity in the northern Upper Rhine Graben, Germany

Near Surface Geophysics, EarlyView.
Abstract A comprehensive multi‐method geophysical strategy is used to investigate two faults in the Northern Upper Rhine Graben. Combining industrial 3D seismic data with our own 2D P‐ and S‐wave seismic, electrical resistivity tomography (ERT) and ground‐penetrating radar (GPR), we created comprehensive subsurface images of the faults. 3D seismic data

Geomorphology and pedology

GEOUSP: Espaço e Tempo (Online), 2003
Este trabalho procura discutir questões que, a princípio, parecem obvias como o que é geomorfologia e pedologia, mas que quando do trato acadêmico revelam sua complexidade e discussão sobre seu entendimento e ação. Para isso um breve recuperar histórico de seu entendimento e sua utilização se fez necessário bem como as relações que se estabelecem entre

Paving the Way for Improved Representation of Coupled Physical and Biogeochemical Processes in Arctic River Plumes—A Case Study of the Mackenzie Shelf

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Processes affecting the transformation of riverine dissolved organic carbon (DOC) across the land‐to‐ocean aquatic continuum are still poorly constrained in Arctic models, leading to large uncertainties in simulated air–sea CO2 fluxes of the coastal periphery.

Decadal Variability of Differential Frost Heave on Incipient Sorted Patterned Ground in the Southern Japanese Alps

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Differential frost heave between fine (earthy) and coarse (gravelly) domains was monitored over 10 years (2013–2023) on a mountain‐top flat ground subjected to both frequent diurnal and deep seasonal freezing. Monitoring objects include, ground heave, soil temperature down to 55 cm, soil moisture, air temperature, rainfall, and snow depth. The
