Discriminating Arid Ecosystems and Tracking Desertification Dynamics: Evidence From Grain‐Size End‐Member in the Manas River Basin, Northern Tianshan Mountains

Land Degradation &Development, EarlyView.
ABSTRACT The ecosystem of the Manas River Basin, composed of mountains, oases, and deserts, constitutes an ideal natural laboratory for investigating surface processes and environmental evolution in arid regions. Elucidating the provenance, transport dynamics, and climate response mechanisms of surface sediments in this system is critical for advancing

Response of the stream geomorphic index to fault activity in the Qujiang fault on the southeastern margin of the Qinghai-Xizang Plateau

地震科学进展
Based on 12.5 m resolution ALOS_PALSAR DEM data and hydrology analysis tool in Arcgis10.6, the stream geomorphic indices such as slope, relief degree of the land surface (RDLS), hypsometric integral (HI) and stream length gradient (SL) along the Qujiang ...

Geomorphic systems, sediment connectivity and geomorphodiversity: relations within a small mountain catchment in the Lepontine Alps [PDF]

, 2020
Mountain regions are characterized by a spatial geomorphic heterogeneity that confers to the environment a significant geomorphodiversity, functioning as a substrate for biodiversity.

Integrating Machine Learning and StoDyM for Check Dam Site Selection on the Loess Plateau, China

Land Degradation &Development, EarlyView.
ABSTRACT Severe soil erosion in the Loess Plateau has led to significant land degradation, threatening agricultural productivity and ecosystem stability. Check dams, as a critical soil–water conservation measure, have proven effective in mitigating sediment loss and reclaiming farmland.

Geomorphic expression of a tectonically active rift-transfer zone in southern Ethiopia [PDF]

, 2022
The Gofa Province and the Chew Bahir Basin of southern Ethiopia constitute tectonically active regions, where the Southern Main Ethiopian Rift converges with the Northern Kenya Rift through a wide zone of extensional deformation with several north to ...

Modeled Subsidence of Permafrost Terrain 2025–2050: North‐Central Alaska

Permafrost and Periglacial Processes, EarlyView.
ABSTRACT A large fraction of the Alaska terrain is underlain by regolith that contains excess ice (ice that in volume exceeds the natural pore space). Possible loss of excess ice would lead to ground subsidence, which in turn would disturb and destabilize the ground surface.

On the Time Indices in the Geomorphic Histories of the Coastal Sand Dunes

The Quaternary Research (Daiyonki-Kenkyu), 1975
Many coastal sand dunes are distributed along the present strand-line of Japan. The ages of formations of those sand dunes can be classified into three types, as the Pleistocene sand dunes, “Older”and“Younger”Dunes in Holocene.The Older Dunes in Holocene were formed during the stage of the highest sea level in the Flandrian transgression, which was ...
