Characterisation of the surface morphology of an alpine alluvial fan using airborne LiDAR [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2008
Alluvial fans of alpine torrents are both natural deposition areas for sediment discharged by floods and debris flows, and preferred sites for agriculture and settlements.

Dose dependency of aliquot sizes and age models from modern alluvial fan deposits of Helan Mountain, China

open access: yesFrontiers in Earth Science, 2022
Alluvial fan deposits are identified as evidence of regional climatic variations and tectonic events; therefore, it is crucial to establish absolute time series by dating alluvial fan deposits.

Alluvial Fans on Contact Karst: an Example from Matarsko Podolje, Slovenia.

open access: yesActa Carsologica, 2007
Several types of contact karst are found within the Slovenian karst, but the most common is the ponor type, which usually appears between flysch and limestone.

Geologic context of geodetic data across a Basin and Range normal fault, Crescent Valley, Nevada [PDF]

open access: yes, 2004
Geodetic strain and late Quaternary faulting in the Basin and Range province is distributed over a region much wider than historic seismicity, which is localized near the margins of the province.

Evaluating the effect of geomorphology on the vegetation type and density of Foshtanq alluvial fans, Sabzevar [PDF]

open access: yesجغرافیا و توسعه, 2018
There has been always an interaction between geomorphic landforms and vegetation type and density. Alluvial fans are among landforms having considerable effect on vegetation.

Weathering process of the alluvial fans in western Sichuan basin, eastern margin of the Tibetan Plateau

open access: yesNatural Hazards Research, 2021
Correlating morphological surfaces, such as terraces and alluvial fans, is necessary in geomorphology researches. Gravel characteristics have been analysed to estimate the weathering degree.

Geomorphology of the coastal alluvial fan complex Guanillos, northern Chile

open access: yesJournal of Maps, 2019
The evolution of alluvial fans on the narrow coastal plain of the Atacama Desert in northern Chile is so far poorly investigated. Therefore, a detailed geomorphological map at a scale of 1:7500 of a coastal alluvial fan complex at Guanillos (21°58′S, 70 ...

The Temporal-Spatial Distribution of Shule River Alluvial Fan Units in China Based on SAR Data and OSL Dating

open access: yesRemote Sensing, 2013
Alluvial fans in arid and semi-arid regions can provide important evidence of geomorphic and climatic changes, which reveal the evolution of the regional tectonic activity and environment.
