Repeated Pleistocene Permafrost Episodes in the Western Pannonian Basin

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT Concerning the study of past periglacial processes, the Pannonian Basin is a key area as it contains the southernmost frost polygons found in Central Europe. The presence or absence of permafrost is still, however, a matter of debate, and data on the timing of frost action are also scarce.

Fundamental Hydraulic Geometry Relations as an Accessible Tool for Identifying Channel Instability Over National Scales

River Research and Applications, EarlyView.
ABSTRACT The geometry of alluvial river channels can give insight into their stability, which can inform predictions of morphological change, flood risk and ecological degradation. Fundamental hydraulic geometry relations can be used to estimate the equilibrium dimensions of stable river channels by evaluating the balance between the erodibility of bed

Geomorphology of the northwestern Kurdistan Region of Iraq: landscapes of the Zagros Mountains drained by the Tigris and Great Zab Rivers

Journal of Maps, 2021
We present the geomorphological map of the northwestern part of the Kurdistan Region of Iraq, where the landscape expresses the tectonic activity associated with the Arabia-Eurasia convergence and Neogene climate change.

Using Deep Learning AI to Detect Riparian Vegetation Recovery Following a Major Flood in the Brisbane River

River Research and Applications, EarlyView.
ABSTRACT Post‐flood riparian vegetation recovery demands significant attention; however, the complexity of traditional remote sensing methods often hinders environmental managers from implementing rapid vegetation monitoring. This paper developed a model using a Deep Learning Model within ArcGIS to classify and detect recovery of vegetation with high ...

The Sites of Kirchhellen and Weeze, Lower Rhine Bay/Germany, with an Elder Acheulean: starting points for research into the problems of recognizing stone-artefacts in pebble-accumulations of fluviatil terraces [PDF]

Eiszeitalter und Gegenwart, 1996
The continuing critic by part of the prehistorians, including the principal rejection of pieces found in and on fluvial terraces without additional archaeological documents, which docs include Kirchhellen and Weeze, caused the author to continue research

Pleistocene terraced fluvial succession, northern slope of Torino Hill [PDF]

Quaternary International, 2007
Abstract A Pleistocene terraced fluvial succession is found on the northern slope of the Torino Hill. This succession consists of many relics of flat surfaces, separated by scarps, often associated with sandy and silty deposits, perched from 30 to 400 m on the Po Plain. Terraced surfaces at high levels are more deformed, dissected and mostly deprived

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

Geomorphology of fluvial deposits in the middle Tocantins River, eastern Amazon

Journal of Maps, 2020
This paper presents the geomorphological mapping at a 1:100,000 scale of fluvial deposits in the middle Tocantins River. The region preserves an important sedimentary archive of environmental changes of the Amazon and Cerrado biomes.
