The historical trend of aggradation in stream beds Europe';s mountain and piedmont areas has been reversed since the beginning twentieth century to a general tendency towards narrowing incision. After an overview some causes geomorphological effects river bed incision, description case studies alpine rivers, this paper aims assess how phenomenon affects ecosystems alluvial plains. questions addressed are, particular, effect incision on sediment redistribution during floods, habitat diversity...
ABSTRACT This study quantifies for the first time influence of flow regulation on river thermal behaviour an ungauged basin located in central‐eastern Argentina. A 30‐day data set continuous summer hourly was assembled eight water temperature gauging sites deployed along main channel upstream and downstream from impoundment. Analysis methods include descriptive statistics daily data, classification diurnal regimes by relative differences ‘shape’ ‘magnitude’ thermographs (RSMC),...
Abstract The restoration of floodplain woodlands demands an understanding the linkages between process, form and past management history at both a local catchment scale. Site reach scale processes that influence species composition woodland are described with particular focus on relationships hydrological sediment inputs to floodplains regeneration response by tree species. importance integrating natural science knowledge gained site decisions taken water allocation priorities is then...
This paper focuses on the contribution of fluvial geomorphology to flood management. We define what geomorphologists understand by "fluvial risk" and examine relationship between hazards. The details how can present innovative approaches prevention, river maintainance floodplain restoration. Management soil erosion floodwaters is key question in plateaus plains northern France. In mountainous terrain, strong connectivity slopes high order streams induces permanent risk for local people...
One of the purposes dendrogeomorphic studies is to provide long and continuous reconstructions mass movements detect climate-induced trends in process activity. The development regional chronologies—in which information from different sites are aggregated—is often needed identify process–climate relations overcome local-scale specificities, sparse data available for individual extract a signal that common larger region possibly driven by past climate fluctuations or large-scale environmental...
ALS-derived raster visualization techniques have become common in recent years, opening up new possibilities for subtle landform detection earth sciences and archaeology, but they also introduced confusion users. As a consequence, the choice between these is still mostly supported by empirical knowledge. Some attempts been made to compare techniques, there lack of analytical data. This work proposes method, based on gradient modelling spatial statistics, analytically assess efficacy...
Abstract The CM pattern is a technique used for describing textural patterns and depositional processes. Over the last 15 years in Rhône watershed, has been intensively to describe actual functioning of aquatic terrestrial environments river its tributaries. Results from this research led us propose global more adapted floodplain environments, on which geomorphological units are mapped according their position within graph. In addition, data collected large range fluvial outwash plains...
This study analyses recent river-bed incision in the northern Alps (France). began after second world war and, initially, affected mainly river channels of large alpine valleys ; exists also on many mountain rivers but is less extensive because bed-rock outcrop. The very severe : at present, are incised to 3-4 metres and long profile lowering several exceeds locally 8 14 rates exceeding 50 cm/year were frequent during period 1950- 1970. channel results from interaction between a) a natural...
Abstract Man‐induced channel changes within Alpine alluvial rivers are investigated. For the middle Arve river, a series of long profiles surveyed between 1856 and 1981 show deep rapid degradation since beginning 1950s. This tendency is related to gravel extraction, weir construction, embankment, shown characterize rivers.
Nitrogen dynamics were investigated in the top centimeters of bottom sediment three different geomorphologic units (riffles, sand bars, pools) and along two contrasted reaches (nitrogen-rich, nitrogen-poor) a rural stream. Some predictions links between geomorphology processes verified: (i) hydrological exchanges nitrification lower pools than riffles whereas (ii) ammonification denitrification higher pools. Studies potential six other N-rich streams support these conclusions demonstrate...
A palaeoenvironmental study of a palaeochannel within the lower alluvial floodplain Allier River, France, has been carried out at high temporal resolution. Research was based upon multi-proxy approach using different sedimentological (magnetic susceptibility, sediment texture and loss on ignition) palaeoecological (pollen, non-pollen palynomorphs (NPPs), diatoms – indicators). The dated from six radiocarbon dates spans second to eleventh century AD. cultural landscape history this...
Actuellement, un consensus a été atteint pour protéger et restaurer les bras morts. Par conséquent, il est important de comprendre le fonctionnement ces zones humides. Á notre connaissance, la distribution spatio-temporelle des diatomées, macrophytes macroinvertébrés benthiques, en relation avec géomorphologie n'a pas étudiée manière approfondie.Dans amont intermédiaire, faible température l'eau fortes concentrations ioniques ont révélé une connexion nappe. De plus, seuil géomorphologique,...
