ABSTRACT Riverine ecosystems are recurrently rejuvenated during destructive flood events and vegetation succession starts again. Poplars (i.e. species from Populus genera) respond to hydrogeomorphological constraints, but, in turn, also influence these processes. Thus, poplar development on bare mineral substrates is not exclusively a one‐way vegetative process. Reciprocal interactions adjustments between sediment dynamics their life cycle lead the emergence of biogeomorphological entities...
Abstract Populations of the riparian pioneer species Populus nigra L. which establish on alluvial bars within river channels modulate sediment dynamics and fluvial landforms. Dense cohorts P. have colonized gravel point along channelized River Garonne, France, during last 20 years enhanced vertical, lateral longitudinal development bars. For this period, geomorphic characteristics two wooded laterally stable are closely linked to spatial distribution intensity establishment resistance...
Abstract Feedback between hydrogeomorphological processes and riparian plants drives landscape dynamics vegetation succession in river corridors. We describe the consequences of biogeomorphological feedback on formation vegetated fluvial landforms based observations from channelized Isère River France. The channel was laterally confined with embankments mostly straightened. From beginning 1970s to end 1990s, alternate bars were progressively but heavily colonized by vegetation. This context...
Rivers have an intricate relationship with the vegetation that colonizes them. Riparian plants, capable of thriving within river corridors, both respond to and influence geomorphology. Yet interactions between morphodynamics tend be context specific, making it challenging generalize findings locations. The current comprehension interaction physical processes, especially its effects on morphodynamics, still lacks clarity. This article examines numerous sources variation in plant responses to,...
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 Comparative assessment of stone weathering intensities and bioclimatic conditions was conducted at four temples located in cleared forested sites the Angkor Park, based on similar protocols. Four thousand sculpted lotus petals carved same grey sandstone were categorized by using two customized scales intensity, climate monitoring from December 2008 to November 2009. Whereas 70% are almost completely destroyed mechanical areas, 74% environments appear be totally free only affected...
Abstract Past fluvial biogeomorphic succession dynamics, i.e. reciprocal interactions and adjustments between vegetation growth landform construction, were monitored reconstructed using stereophotogrammetry. The four‐dimensional spatio‐temporal stereophotogrammetric analyses based on the use of archival analogue digital aerial photographs. First, we tested relevance technique to produce floodplain terrain models (DTMs) cover height (CHMs) dynamic River Allier, France, compared derived from...
Native to West Africa, Spathodea campanulata (African tulip tree) is frequently viewed as a shade-intolerant invader. It commonly colonizes roadsides, human-disturbed forests, and abandoned agricultural land in tropical islands, where it can then become dominant secondary forests. Some authors have suggested that the seedlings may be shade-tolerant able establish closed-canopy forest, but shade tolerance of has never been evaluated. We identified tolerated light environments S. wet forests...
Riverbank erosion is an essential morphodynamic process for the improvement of river health and ecohydrogeomorphological functioning alluvial rivers. Lateral channel dynamics sediment supply caused by bank largely create maintain heterogeneous in-channel habitats fauna aquatic or riparian plant species. However, humans very early started to stabilize riverbanks in order favour navigation prevent valuable land infrastructures close from eroding. During 20th century, protection works such as...
The development of the Neolithic way life in western Mediterranean during sixth millennium cal. BC is consequence spread populations from Near East after successive stages cultural remodelling. Despite clear contribution Eastern and Aegean to economic technical changes that happened west, little known here about their symbolic legacies, because scarcity representations ritual evidences associated earliest contexts. Excavations at rock shelter Pendimoun (southeastern France) yielded first...
Recently, deglaciated landscapes are ideal natural arenas to investigate ecological succession processes. However, ground data acquisition remains complicated as glacier forefields often difficult access and fieldwork possibilities remain limited. Remote sensing offers an opportunity bypass this issue increase spatial temporal coverage of parameters. The Landsat satellites (5 8) provide reflectance for the past 40 years, which align with recent phenomena retreat related geomorphological...
Abstract Three Romanesque churches of the Bourbonnais region in French Massif Central have been investigated. These date back to twelfth century, and are mainly built red white sandstones. Their ashlar blocks were extensively repointed mid-twentieth century with cement-rich mortar. In order quantitatively assess impact repointing on decay rates sandstones, following methods used: dating reference surfaces (‘zero datum levels’) based stone-dressing marks, stone-by-stone terrestrial LiDAR...
Abstract This paper presents the first results of geoarchaeological study an unusual hilltop wetland, located within protohistoric proto‐urban site Corent in French Massif Central. small depression offers exceptionally local sedimentary record that provided valuable data on long‐term human–environment interactions, as well proto‐urbanization millennium B.C.E. Field survey revealed a major archaeological discovery: large ensemble 114 Iron Age storage pits excavated clayey deposits. The...
