Local Evolution of a Prenoon Drainage Plume

Geophysical Research Letters
Plasmaspheric drainage plumes are typically observed in the postnoon sector during geomagnetic storms, but their local evolution in the prenoon sector remains poorly understood.

Geomorphological analysis of drainage changes in the NE Apennines piedmont area: the case of the middle Tavo River bend (Abruzzo, Central Italy)

Journal of Maps, 2020
This work presents a tectonic geomorphology analysis of a river bend in the middle Tavo River valley, in the piedmont area of the NE Apennines (Abruzzo Region), between the eastern slope of the chain (Gran Sasso Massif) and the Adriatic coast.

Investigation on Coal Skeleton Deformation in CO2 Injection Enhanced CH4 Drainage From Underground Coal Seam

Frontiers in Earth Science, 2021
To reveal the evolution law of coal skeleton deformation during the process of CO2 flooding and displacing CH4 in coal seam, a fluid-solid coupling mathematical model of CO2 injection enhanced CH4 drainage was established based on Fick’s law, Darcy’s law,

Effect of Large-Scale Mining Drainage on Groundwater Hydrogeochemical Evolution in Semi-Arid and Arid Regions

Frontiers in Environmental Science, 2022
Groundwater evolution and circulation in coal mining areas will be significantly affected by natural processes and human activities. However, the impacts of large-scale mining drainage on groundwater hydrochemistry are unclear in the semi-arid and arid ...

Subglacial meltwater routes of the Fennoscandian Ice Sheet

Journal of Maps, 2022
Subglacial drainage systems are crucial elements of glaciers and ice sheets because they modulate ice flow velocity. However, logistical challenges of measuring subglacial processes beneath contemporary ice and natural limitations in long-term monitoring

Pliocene to Early Pleistocene Drainage Reorganization in Eastern Tibet Inferred From Detrital Zircons

Geophysical Research Letters, 2021
The drainage evolution in eastern Tibet during the India‐Eurasia collision has attracted considerable attention because of its critical link to topographic development and plateau growth, but the discussion still persists.

Post-lacustrine evolution of a tectonically-controlled intermontane basin: Drainage network analysis of the Mercure basin, southern Italy

Frontiers in Earth Science, 2023
Topographic analysis, drainage network morphometry, river profile analysis, and spatial distribution of fluvio-lacustrine terraces have been used to reconstruct the drainage network evolution in the Mercure River basin, a large intermontane tectonic ...

Ice sheet and palaeoclimate controls on drainage network evolution: an example from Dogger Bank, North Sea [PDF]

Earth Surface Dynamics, 2020
Submerged landscapes on continental shelves archive drainage networks formed during periods of sea-level lowstand. The evolution of these postglacial drainage networks also reveals how past climate changes affected the landscape.
