Topography and Substrate Lithology Control the Position of Fluvial Channels on a Drained Lake Floor, the Case of the Postglacial Ain Valley (Eastern France)

Quaternary
The development of fluvial systems over long time scales is a complex interplay of tectonic, climatic, and lithological factors. The initiation and location of fluvial channels in the landscape is less well understood.

SOILS NATURAL FERTILITY OF MADEIRA-RO FLUVIAL PLAIN: A PHYSIC-CHEMISTRY ANALYSIS (CEC, m% E V%) OF THE STRETCH FROM PORTO VELHO-RO TO HUMAITÁ-AM [PDF]

Sociedade & Natureza, 2005
This work evaluates natural soil fertility on plain and flooded terrace areas, at Madeira River-RO fluvial plain, based on physics and chemicals analyses, (pH, OM, Al+2 + H+, exchange bases K+; Ca+2; Mg+2 e Al+3), physic-chemical (CEC, m% and V%), from ...

Slope and sediment size in the development of pebble and cobble beaches with low permeability

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
We studied beaches composed of coarse‐grained beaches. In spite that the occurrence of an impermeable layer at a low depth that reduces its permeability, the correlation between the beach slope and the sediment size corresponds to what was expected, and the underlying and cohesive sediment reached the same slope of the beach.

Variability in the Vineyard: A Multi‐Method Approach in Determining Grapevine Evapotranspiration Across Different Varietal Blocks

Hydrological Processes, Volume 40, Issue 8, August 2026.
To address the variability of evapotranspiration (ET) in vineyards, a multi‐method approach combining the use of in‐field atmometer ET gauges and the FAO‐56 dual crop coefficient procedure was employed. Reference ET and crop ET adjusted for water stress resulted in consistencies between white varietals, while Pinot Noir exhibited reductions in ...

Columnanidus calitzdorpensis ichnogen. ichnosp. nov: A new Middle Pleistocene subterranean termite trace fossil from South Africa

Journal of Quaternary Science, Volume 41, Issue 6, Page 933-949, August 2026.
ABSTRACT Termites are landscape geo‐engineers whose nesting activities substantially modify the physical and chemical properties of soils. Fossilised termite nests commonly constitute the only identifiable evidence of ancient termite activity and represent valuable trace fossil archives for reconstructing past environments.

Phosphate modulates elemental and macromolecular composition of unicellular nitrogen‐fixing cyanobacteria

Limnology and Oceanography, Volume 71, Issue 8, August 2026.
Abstract The C : N : P of nitrogen‐fixing cyanobacteria regulates phosphate‐limited nitrogen fixation in the ocean yet the causes and range in variation C : N : P is not well constrained. Here we quantify the C : N : P and underlying macromolecular composition of Crocosphaera.

Spatial Variability and Drivers of Salt Marsh Cliff Erosion in the Dutch Wadden Sea: From Observation to Simulation

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 8, August 2026.
Abstract Lateral erosion of salt marshes via cliff retreat is a primary cause of global marsh loss, driven by interactions between hydrodynamics, sediment, and vegetation. While previous studies show a linear relationship between wave power and cliff retreat, models based on this relationship are largely unvalidated for short‐term (sub‐yearly) and ...

Paleoseismic Evidence of Recent Co‐Seismic Ruptures in Western Tierra del Fuego, Chile

Tectonics, Volume 45, Issue 8, August 2026.
Abstract The Magallanes‐Fagnano fault (MFF) in Tierra del Fuego (TDF) is a major left‐lateral transform boundary between the South American and Scotia plates. While surface ruptures associated with the 1949 earthquakes have been documented in Argentina east of the Fagnano Lake, their extension to the west remained uncertain.

Quaternary fluvial terraces of the Tiber Valley: geochronologic and geometric constraints on the back-arc magmatism-related uplift in central Italy

Scientific Reports, 2017
Through a geomorphological study relying on statistically assessed classes of hilltop elevations, we reconstruct a suite of paleo-surfaces along the Tiber River Valley north of Rome that we identify as fluvial terraces formed by interplay between global ...
