Geomorphology of Talacasto alluvial fan, Precordillera of San Juan, Argentina [PDF]

open access: yesJournal of Maps, 2017
We present a 1:50,000 geomorphological map of the Talacasto river alluvial fan (93 km2), located in the Central Andean Precordillera of Argentina. The aim of this map is to identify and classify dynamic and potentially destructive geomorphological ...

Effects of repeated paleoearthquakes on the Alhama de Murcia Fault (Betic Cordillera, Spain) on the Quaternary evolution of an alluvial fan system [PDF]

open access: yesAnnals of Geophysics, 2003
In this work we present a study of an alluvial fan system, which is affected by the Quaternary activity of the leftlateral, reverse Alhama de Murcia Fault (Betic Cordillera). Paleoseismic studies in this area yield data that can be compared and

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.

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 ...

Sedimentation of open-framework gravels in alluvial-fan settings: Quaternary Poplar Fan, northwest China [PDF]

open access: yes, 2021
Open-framework gravels (OFGs) form common lithofacies of alluvial fans. However, inferences of their mechanisms of transport and deposition, and of controls on their distribution in alluvial-fan successions, remain difficult, limiting our ability to ...

Late Quaternary alluvial fans, debris cones and talus cones in the Grampian Highlands, Scotland [PDF]

open access: yes, 2012
Alluvial fans, debris cones and rockfall talus cones are widespread in upland Britain, but remarkably little is known about their characteristics, development and significance. This research project has three main objectives: 1.

Enhancing flood hazard estimation methods on alluvial fans using an integrated hydraulic, geological and geomorphological approach [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2018
Due to the uncertainty concerning the location of flow paths on active alluvial fans, alluvial fan floods could be more dangerous than riverine floods.

Active and relict alluvial fans on contact karst of the Vrhpoljska brda hills, Slovenia

open access: yesActa Geographica Slovenica, 2009
Several types of contact karst are found within the Slovenian karst, but the most common is the ponor type, which usually develops at boundaries between flysch and limestone. One of these types is in the area of Vrhpoljska brda.
