Precipitation is one of the main factors which controls surface processes and landscape morphology. Large orogenic belts such as Himalayas control precipitation distribution a result orographic effects due to their prominent relief. However, difficult monitor because mountain regions are largely inaccessible therefore not sufficiently covered by ground-based gauge stations. The complexity resulting from interaction between elevation climatic lack precise meteorological data thus limit our...

Abstract Quantifying sediment transport and storage in fluvial systems is fundamental for understanding the transfer of eroded materials from source to sink. Here, we investigated potential a combined approach using luminescence measured modern sediments numerical simulations quantify rivers. We acquired data at single‐grain scale on feldspar Waimakariri Rakaia braided rivers (New Zealand) post infra‐red stimulated protocol. considered three metrics analysis equivalent dose ( D e )...

Peneplanation of mountain ranges is generally considered the result long‐term erosional processes that smooth relief and lower elevation near sea level. Therefore peneplain remnants at high in are used to infer posttectonic surface uplift. Such an interpretation has been proposed for Pyrenees where high‐elevation, low‐relief surfaces rose up more than 2000 m. Because Pyrenean foreland basins filled with very thick continental deposits, which have buried early jagged landscape, we challenge...

Abstract The evolution of a fluvial landscape is balance between tectonic uplift, erosion, and sediment deposition. erosion term can be expressed according to the stream power model, stating that incision proportional powers river slope discharge. deposition as flux divided by transport length. This length defined water times scaling factor ζ. exerts major control on dynamics, spacing sedimentary bedforms, or overall erosional behavior. Yet, this difficult measure either in lab field. Here,...

Abstract Sediment supply ( Q s ) is often overlooked in modelling studies of landscape evolution, despite sediment playing a key role the physical processes that drive erosion and sedimentation river channels. Here, we show direct impact coarse‐grained, hard on geometry bedrock channels from Rangitikei River, New Zealand. Channels receiving coarse bedload are systematically (up to an order magnitude) wider than with no input for given discharge. We also present model experiments channel...

Abstract This article deals with the stratigraphic record of a climatic or tectonic perturbation an experimental coupled catchment‐fan system. Following Bonnet &amp; Crave's results (2003), which suggest that it is possible to differentiate between causes surface uplift erosional topography from sediment flux output, we design new device test this proposition in sedimentary signal. allows study erosion–sedimentation system at laboratory scale for given and changing rainfall rates. On basis...

Fish tanks become fashionable throughout the Mediterranean area between 1st century B.C. and A.D. Because of this narrow chronological window, their link to former sea level, they constitute precious archives investigate relative level (RSL) since Roman period, especially when combined with fossilized marine benthos found attached fish tank walls. Here, we present new results from an integrated analysis a located in colony Fréjus, Southeastern France. The well‐preserved biological remains on...

Abstract Single‐grain post‐infrared infrared stimulated luminescence (SG‐pIRIR) of feldspar has recently been introduced as a method to date Quaternary deposits. The is particularly appropriate for fluvial deposits that cannot be dated by more conventional quartz optically dating and are heterogeneously bleached (i.e. where only part the grains exposed sufficient light remove full signal). Besides age estimation, single grain equivalent dose ( D e ) distributions also reflect variable...

The topography of basements located in intraplate domains has often been interpreted terms planation theory by examining the remnants paleosurfaces. In this paper, we address significance present‐day drainage networks that erode such topographies looking at relief development on Armorican Massif basement (northwestern France). Using digital elevation model (DEM) analysis, massif is characterized large‐scale (∼250 km) variations define high (HEDs). These control pattern setting location main...

Abstract. Intracontinental endorheic basins are key elements of source-to-sink systems as they preserve sediments eroded from the surrounding catchments. Drainage reorganization in such a basin response to changing boundary conditions has strong implications on sediment routing system and landscape evolution. The Ebro Duero represent two foreland basins, which developed growth compressional orogens, Pyrenees Cantabrian mountains north, Iberian Ranges south, Catalan Coastal Range east. They...

Luminescence signals of quartz and feldspar minerals are widely used to determine the burial age Quaternary sediments. Although luminescence bleach rapidly with sunlight exposure, incomplete bleaching may affect ages, in particular fluvial settings where an unbleached remnant signal is commonly encountered modern alluvium. Here, we use single-grain post-infrared IR stimulation (pIRIR) dating show that recent (<11 ka) terraces Rangitikei River (New Zealand) were formed a context non-linear...

Abstract Alluvial fans are hypothesised to record signals of past hydroclimate changes in their depositional chronologies and slopes. However, direct tests this hypothesis have been limited due challenges precisely dating the responses alluvial climate forcing. Here, we present a new chronology alluvial‐fan deposition at Sierra de Aconquija southern Central Andes (27°S) spanning ~300 kyr based on 35 cosmogenic 10 Be‐derived exposure ages eight infrared‐stimulated (IRSL) optically stimulated...

Hillslope processes play a significant role in shaping catchment-scale erosional dynamics. These include mechanisms from granular creep to large-scale morphological changes influenced by tectonic and climatic forces over both short long timescales. Despite advancements quantification methods, granular-level understanding of these remains unclear. Moreover, systematic approach link the variability hillslope across different temporal scales is still lacking. Thus, integrating single-grain...
