, where a variety of typical contact karst depression features can be found. Relict alluvial fans on contact karst are the result of the gradual denudation of alluvial cover from flysch and chemical denudation of carbonate bedrocks in the area of alluvial
fans. Geomorphologic features and processes on alluvial fans, and the influences of alluvial fans on the development of local karst have been investigated in detail. - (IKR)

The role of alluvial fans in the mountain fluvial systems of southeast Spain: implications of climatic change

The role of alluvial fans in the mountain fluvial systems of southeast Spain: implications of climatic change
Alluvial cone ; Alluvium ; Almería ; Arid area ; Climatic variation ; Fluvial dynamics ; Mountain ; Murcia ; Sediment transport ; Semi-arid area ; Spain
This paper deals with the mountain front alluvial fans in the semi-arid areas of Murcia and Almeria provinces. It attempts, by mapping the location of alluvial fans, then their classification into aggrading or dissecting fans, to identify the extent
to which the mountain fluvial systems are buffered by aggrading alluvial fans or exhibit channel continuity through the mountain front environment. It further considers the implications of climatically induced changes between aggradational and dissectional
behaviour on alluvial fans.

Impacts of Holocene climatic variations on alluvial fan activity below snowpatches in subarctic Québec

Impacts of Holocene climatic variations on alluvial fan activity below snowpatches in subarctic Québec
Alluvial cone ; Canada ; Climatic variation ; Dendrochronology ; Holocene ; Nivation hollow ; Periglacial features ; Precipitation ; Quebec ; Snow ; Soil moisture
In the Lake Guillaume-Delisle area of subarctic Québec, storm-generated alluvial fans have been active sporadically throughout the Holocene. In this study, the AA. propose that the persistence of late-lying snowpatches in fan catchments during
Holocene cold episodes promoted alluvial fan activity by lowering the precipitation threshold required to trigger a torential event. This hypothesis was tested by characterizing the depositional processes responsible for alluvial fan formation below
snowpatches, and by reconstructing the Holocene alluvial fan activity.

Environmental controls on the evolution of alluvial fans in Buena Vista Valley, North Central Nevada, during late Quaternary

Alluvial cone ; Climatic variation ; Impact ; Nevada ; Palaeo-environment ; Quaternary ; Sedimentology ; Soil ; Stratigraphy ; Tectonics ; United States of America
This study evaluates the relative influences of the environmental factors on the evolution of alluvial fans in Buena Vista Valley, north-central Nevada. The objectives of this study include : delineating the surficial stratigraphy of the alluvial
fan deposits; relating the stratigraphy of alluvial fans to geomorphic features and deposits associated with the climatic and tectonic history of the basin; establishing a temporal framework for the stratigraphy and comparing it to that developed
regionally by Hawley and Wilson (1965); and, examining the driving forces of aggradation and entrenchment on alluvial fans in Buena Vista Valley.

Late Quaternary alluvial stratigraphy of a low-order tributary in central Texas, USA and its response to climate and sediment supply

Late Quaternary alluvial stratigraphy of a low-order tributary in central Texas, USA and its response to climate and sediment supply
This paper presents the late Quaternary alluvial stratigraphic study of a low-order tributary in central Texas, using Cowhouse Creek as a case study. The AA. correlate episodes of stream incision and alluviation to climate records and to previous
alluvial stratigraphic work conducted along the Brazos River. The temporal alluvial stratigraphic framework of the bedrock-confined Cowhouse Creek valley is out of phase with the alluvial sequence in the larger Brazos River valley.

High Resolution DEMs for the analysis of fluvial and ancient anthropogenic landforms in the alluvial plain of Padua (Italy)

The alluvial plain around Padua results from the sedimentary activity of the Brenta and the Bacchiglione rivers since the last glaciation to the modern times. The inner and oldest part of the city developed on the banks of a former meander
of the Brenta River, later occupied by a minor course, the Bacchiglione. Early archaeological evidence dates back to the final Bronze Age and the first urban settlement started in the Iron Age. The underground of the city centre consists of alluvial sediments

Surface sediment characteristics and present dynamics in alluvial fans of the central Spanish Pyrenees

Surface sediment characteristics and present dynamics in alluvial fans of the central Spanish Pyrenees

Three alluvial fans in the Ribera de Biescas, upper Gállego Valley, and central Spanish Pyrenees, have been studied in order to explain the most recent changes and to identify the spatial organization of the sediment. In the alluvial fans surveyed
, the proximal area is dominated by debris flows, which pass downslope into transitional and fluvial deposits. The AA. explain the most recent activity in alluvial fans in relation to land-use and plant cover changes affecting their catchments during the last few

Alluvial fans as records of Holocene sediment yield in the central Great Plains of southwest Nebraska

Alluvial fans as records of Holocene sediment yield in the central Great Plains of southwest Nebraska
Alluvial cone ; C 14 dating ; Climatic variation ; Geochronology ; Holocene ; Nebraska ; Palaeosol ; Quaternary ; Sediment budget ; Stratigraphy ; United States of America
On alluvial fans, increased rates of sedimentation are directly related to increased sediment yields from their watersheds. Since well developed soils imply prolonged landscape stability, soils that are buried by alluvial-fan deposits are evidence
of a shift, at least locally, toward increased sediment yields. The objective of this paper is to propose a Holocene history of sediment yield increases in the central Great Plains based on the record that buried alluvial-fan soils provide.

Thermoluminescence dating and chemistry of Quaternary sodic alluvial soils in the Venezuelan savanna

Thermoluminescence dating and chemistry of Quaternary sodic alluvial soils in the Venezuelan savanna
Pedological analyses and thermoluminescence dating were carried out on two soil profiles in the alluvial plain of the Orituco River, to determine if the chemical properties of the soil subhorizons are related to the paleoclimatology of the region.

Late Quaternary alluvial history of Nowlands Creek, Hunter Valley, NSW

Late Quaternary alluvial history of Nowlands Creek, Hunter Valley, NSW
The purpose of this paper is to unravel the alluvial history of Nowlands Creek at the archaeological sites. In particular, the river terraces and their stratigraphy, soils and chronology will be evaluated to separate Pleistocene from Holocene

Minimum Froude number and the equilibrium of alluvial sand rivers

Minimum Froude number and the equilibrium of alluvial sand rivers
Computer simulations for sand bed rivers show that the Froude number of the flow tends to a minimum value when the equilibrium river tends to a certain hydraulic geometry. Evidence from 57 alluvial sand material rivers and stable canals shows

Modern alluvial history of the Paria River drainage basin, southern Utah

Modern alluvial history of the Paria River drainage basin, southern Utah
The modern alluvial history of the Paria River basin favors the hypothesis that erosion and filling of channels in semiarid regions is controlled by the size of floods, at least within the last 100 yr. Erosion and entrenchment result from a larger
