“…Even though this inference is strongly dependent on the choice of the reference station for the rock uplift rates, the Austrian reference station at Horn is sufficiently distant from the center of the belt for it to represent a meaningful base level for the Eastern Alps. Indeed, evidence for a recent increase (\5 My) in rock uplift rates was reported from the easternmost margin of the Eastern Alps where an increase in the rates of valley incision was interpreted to reflect consecutive uplift and river capture (Wagner et al 2010). Such wide-spread surface uplift cannot occur through purely isostatic mechanisms.…”

“…Such wide-spread surface uplift cannot occur through purely isostatic mechanisms. Therefore, a tectonic driver needs to be invoked (Wagner et al 2010). We can only speculate as to whether this driver is continued convergence (Grenerczy et al 2005), glacio-isostatic rebound (Gudmundsson 1994), removal of a deep lithospheric root whose downward force previously kept the belt in a state of overcompensation (e.g., Lyon-Caen and Molnar 1989) or a change in subduction polarity beneath the study area (Schmid et al 2004).…”

Denudation rates from cosmogenic 10 Be measured in quartz from recent river sediment have previously been used in the Central Alps to argue that rock uplift occurs through isostatic response to erosion in the absence of ongoing convergence. We present new basin-averaged denudation rates from large rivers in the Eastern and Southern European Alps together with a detailed topographic analysis in order to infer the forces driving erosion. Denudation rates in the Eastern and Southern Alps of 170-1,400 mm ky -1 are within a similar range to those in the Central Alps for similar lithologies. However, these denudation rates vary considerably with lithology, and their variability generally increases with steeper landscapes, where correlations with topographic metrics also become poorer. Tertiary igneous rocks are associated with steep hillslopes and channels and low denudation rates, whereas pre-Alpine gneisses usually exhibit steep hillslopes and higher denudation rates. Molasse, flysch, and schists display lower mean basin slopes and channel gradients, and, despite their high erodibility, low erosion rates. Exceptionally low denudation rates are also measured in Permian rhyolite, which has high mean basin slopes. We invoke geomorphic inheritance as a major factor controlling erosion, such that large erosive glaciers in the late Quaternary cold periods were more effective in priming landscapes in the Central Alps for erosion than in the interior Eastern Alps. However, the difference in tectonic evolution of the Eastern and Central Alps potentially adds to differences in their geomorphic response; their deep structures differ significantly and, unlike the Central Alps, the Eastern Alps are affected by ongoing tectonic influx due to the slow motion and rotation of Adria. The result is a complex pattern of high mountain erosion in the Eastern Alps, which has evolved from one confined to the narrow belt of the Tauern Window in late Tertiary time to one affecting the entire underthrust basement, orogenic lid, and parts of the Southern Alps today.

A better understanding of the Lurbach karst system via a conceptional rainfall-runoff modelAbstract A parsimonious lumped-parameter rainfall-runoff model was tested to determine if it could be used to appropriately represent a karst hydrological system, the Lurbach system in Austria. Simulated and observed hydrographs of spring discharge were favorably simulated for a time period of seven years in spite of the small number of free parameters. Following this period the four year discharge records were only reproducible using strongly different parameter values. Results suggest during this period overflow to neighboring catchments and the capacity of production or routing store have strongly increased. This relationship is also observed in tracer test and baseflow recession data sets and is attributed to the likely redistributions of sediments. Such dynamic processes are rarely accounted for in rainfall-runoff models, and may cause severe prediction uncertainties. However, in the Lurbach system a parsimonious hydrological model was used successfully to characterize changes in hydrological conditions.

We have carried out a several-year-long study of the Amanos Mountains, on the basis of which we present new sedimentary and structural evidence, which we combine with existing data, to produce the first comprehensive synthesis in the regional geological setting. The ca. N-Strending Amanos Mountains are located at the northwesternmost edge of the Arabian plate, near the intersection of the African and Eurasian plates. Mixed siliciclastic-carbonate sediments accumulated on the north-Gondwana margin during the Palaeozoic. Triassic rift-related sedimentation was followed by platform carbonate deposition during Jurassic-Cretaceous. Late Cretaceous was characterised by platform collapse and southward emplacement of melanges and a supra-subduction zone ophiolite. Latest Cretaceous transgressive shallow-water carbonates gave way to deeper-water deposits during Palaeocene-Eocene. Eocene southward compression, reflecting initial collision, resulted in open folding, reverse faulting and duplexing. Fluvial, lagoonal and shallow-marine carbonates accumulated during Late Oligocene(?)-Early Miocene, associated with basaltic magmatism. Intensifying collision during Mid-Miocene initiated a foreland basin that then infilled with deep-water siliciclastic gravity flows. Late Miocene-Early Pliocene compression created mountain-sized folds and thrusts, verging E in the north but SE in the south. The resulting surface uplift triggered deposition of huge alluvial outwash fans in the west. Smaller alluvial fans formed along both mountain flanks during the Pleistocene after major surface uplift ended. Pliocene-Pleistocene alluvium was tilted towards the mountain front in the west. Strike-slip/transtension along the East Anatolian Transform Fault and localised sub-horizontal Quaternary basaltic volcanism in the region reflect regional transtension during Late Pliocene-Pleistocene (<4 Ma).
