“…During the Quaternary glaciation cycles, the area was always located outside the permafrost area. According to the data of Schaller et al (2004), the Quaternary climatic cycles only had minor impacts on the high erosion rates that are observed around 0.65 My ago. Nevertheless, it cannot be discarded that the observed Mid-Pleistocene increase in erosion rates resulted from the combination of increased tectonic activity during a period with strong increase in the magnitude of the glaciation cycles.…”

“…In this module, additional information (constraints, hill top point features and linear ridges) was used to optimize the interpolation and produce a more accurate DTM. The natural sinks that remain in the DTM were filled using the Hydro-Tools ArcGis extension (Filling-Sink tool) written by Schäuble (2000). We also applied the sink identification and filling method provided by Wang and Liu (2006), and compared the results.…”

Abstract. Geomorphic processes that produce and transport sediment, and incise river valleys are complex; and often difficult to quantify over longer timescales of 10 3 to 10 5 y. Morphometric indices that describe the topography of hill slopes, valleys and river channels have commonly been used to compare morphological characteristics between catchments and to relate them to hydrological and erosion processes. This study aims to analyze the link between tectonic uplift rates and landscape morphology based on slope and channel morphometric indexes. To achieve this objective, we selected 10 catchments of about 150 to 250 km 2 across the Ardennes Massif (a Palaeozoic massif of NW Europe, principally located in Belgium) that cover various tectonic domains with uplift rates ranging from about 0.06 to 0.20 mm yr −1 since mid-Pleistocene times. The morphometric analysis indicates that the slope and channel morphology of third-order catchments is not yet in topographic steady-state, and exhibits clear convexities in slope and river profiles. Our analysis indicates that the fluvial system is the main driver of topographic evolution and that the spatial pattern of uplift rates is reflected in the distribution of channel steepness and convexity. The spatial variation that we observe in slope and channel morphology between the 10 third-order catchments suggests that the response of the fluvial system was strongly diachronic, and that a transient signal of adjustment is migrating from the Meuse valley towards the Ardennian headwaters.

“…He explains the change from the 'wide valley' Gelasian-Early Pleistocene terraces to the incised 'narrow-valley' Middle Pleistocene to Holocene terraces as due to the change from low-amplitude to high-amplitude climatic cycles. Schaller et al (2004) calculate, based on the cosmogenically dated terrace sequence of the River Meuse catchment, palaeoerosion rates of 25 30 mm/kyr for the period from 1.3 to 0.7 Myr and 80 mm/yr for the period after 0.7 Myr. They attribute this signifi cant increase of erosion not only to changes of climatic but also to tectonic boundary conditions.…”

Knowledge of the evolution of Spanish fluvial networks has improved during recent years as more river systems have been studied and more geochronological data has become available. However, the chronological framework is a major issue as the range of applications is limited by methodological constraints and spatial coverage is sparse. Integration of 'absolute' dating methods with biostratigraphy and palaeomagnetism permits the recent evolution of these river systems to be reviewed. The timing of incision from the Late Neogene to the present varies between the major Iberian fluvial systems, depending on the substrata and tectonic settings. Early Pleistocene and older fluvial sequences in the core areas of the Iberian Peninsula provide a more extensive record of fluvial evolution and are better preserved than the terrace flights in the coastal lowlands. Middle Pleistocene sequences are well developed in most of the major river systems in Iberia, particularly those of the Tajo, Guadalquivir and Aguas River, and frequently represent the principal climatic cycles of that period, although tectonic and sea-level effects can also be seen. For Late Pleistocene to Holocene times, the scheme becomes more complex. Our review suggests that each river system has responded differently to local and regional climate control, glacial and periglacial processes in headwaters in high mountain areas, glacio-eustatic sea-level changes and local and regional tectonic patterns.

“…Al inventories remain unmodified downstream due to fast ( 10 5 yr) sediment transfer and negligible external input; 2) nuclide abundances increase downstream while 26 Al/ 10 Be ratios remain constant, which indicates long-term ( 10 5 yr) near-surface particle trajectories, or input from nuclide-rich, burial-free sediment sources; 3) nuclide abundances decrease downstream, suggesting significant radioactive decay during slow sediment transfer with lengthy burial intervals (Granger et al, 1996;Granger and Muzikar, 2001;Schaller et al, 2004), 25 or input from nuclide-poor, long-buried sources.…”
