OSL Characterisation of Two Fluvial Sequences of the River Usmacinta in its Middle Catchment (SE Mexico) [PDF]

, 2014
The report summarizes luminescence profiling, initially using a SUERC PPSL system in Mexico, and laboratory analysis at SUERC, used to characterise the stratigraphy and interpret sedimentary processes in terrace deposits of the Usumacinta River, SE ...

Reconstructing human‐induced geomorphic changes through historical maps and multitemporal remote sensing data in the Cancano–San Giacomo di Fraele reservoirs (Central Alps, Italy)

Earth Surface Processes and Landforms, Volume 51, Issue 3, March 2026.
Reconstructing ~200 years of landscape change at the Cancano–San Giacomo hydroelectric system (Central Alps), we integrate historical cartography, archival photographs, multitemporal aerial/satellite imagery and field validation to map pre‐ and post‐impoundment landforms.

Pleistocene geochronologies for fluvial sedimentary sequences: an archaeologist's perspective [PDF]

, 2005
Current models of Pleistocene fluvial system development and dynamics are assessed from the perspective of European Lower and Middle Palaeolithic stone tool assemblages recovered from fluvial secondary contexts. Fluvial activity is reviewed both in terms

Global Comparison of Aqueous Geochemistry and Dissolved H2/CH4 in Continental Low Temperature Serpentinization–Influenced Environments

Hydrological Processes, Volume 40, Issue 3, March 2026.
Conceptual diagram of hydrological and geochemical processes within the Santa Elena Ophiolite, Costa Rica. It highlights watershed cross‐sections, soil genesis, hyperalkaline Type II waters (pH > 11.6) with calcite crust and trapped H2/CH4 gases, seepage into surface waters, storm‐impacted stream profiles, weathered vs.

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 ...

Using Geophysical Observations of a Tracer Injection in a Riparian Aquifer to Explore How Bimodal Transport and Mixing Influences Nitrate Processing

Hydrological Processes, Volume 40, Issue 3, March 2026.
Our results embrace a simple conceptual model of preferential flow to illuminate the relationships among riparian groundwater nitrate concentration, flow dynamics, and substrate composition in stream corridors loaded with elevated nitrate from agricultural activities.

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.

Aeolian and Biogeochemical Transformations of Detrital Gold Morphology in the Pool Burn Basin, Central Otago, New Zealand

New Zealand Journal of Geology and Geophysics, Volume 69, Issue 1, March 2026.
The Pool Burn basin is a tectonic depression that became almost isolated from the regional drainage system by river reorientation during Pleistocene uplift of surrounding ridges. Consequently, detrital gold in the basin was largely locally derived, from supergene zones on orogenic deposits and recycled from paleoplacers in erosional remnants of Miocene

Textural and Lithologic Differences of Cretaceous, Tertiary, and Quaternary Gravels of South Arkansas [PDF]

, 1987
Stream gravels have been derived from the Ouachita Mountains since at least Cretaceous times. Past studies have assigned ages to gravel deposits in the basins of the Saline and Little Missouri Rivers on the basis of altitude above local floodplains. This

Fluvial terrace dating using in situ cosmogenic {sup 21}Ne

, 1994
Through the analysis of cosmic-ray produced radio-genic and stable nuclide concentrations, specifically {sup 21}Ne, we hope to date certain geomorphic features located along the tributaries of the Colorado River in the Eastern Grand Canyon and the Rainbow Plateau located in Utah.
