By means of the physical process-based modeling approache to computing coastal and estuarine hydrodynamic and morphodynamic processes, an integrated model system was developed to simulate tides, waves, currents, winds, sediment transport, and morphological changes in coastal and estuarine regions. This paper presents an overview of this integrated morphological process modeling system consistin...

Various large-scale risk maps show that the eastern part of Austria, in particular Pannonian Basin, is one regions Europe most vulnerable to wind erosion. However, comprehensive assessments severity and extent erosion are still lacking for this region. This study aimed prove results by developing high-resolution target area. For this, we applied a qualitative soil assessment (DIN 19706) with lo...

[1] Climate change indirectly alters the distribution of tectonic uplift at active orogens by modifying the action of surface processes, which in turn alters mountain topography. The impact of alpine glaciation on tectonic activity is explored here. The predictions of previous analytical, critical wedge models are compared with the output of a numerical model that explicitly couples rock uplift...

Quantifying the erosional and kinematic evolution of orogenic plateaus has been limited by insufficient age constraints on their deformation and erosion histories. Palinspastic restorations suggest the central Andean fold-thrust belt and plateau evolved concurrently in Bolivia. We present an analysis that synthesizes 19 new and 32 previous apatite and zircon fission-track and (U–Th)/He mineral ...

[1] We investigate the effect of systematically varying erosion intensity (K) on the geometry and kinematics of fold‐and‐thrust belts modeled using equivalent conditions in physical and numerical experiments. Similar material properties and boundary conditions were used to compare numerical experiments to those modeled in the sandbox using an erosion rule that removes mass from the scaled sand ...

Phosphorus loss from bank erosion was studied in the catchment of River Odense, a lowland Danish river basin, with the aim of testing the hypothesis of whether stream banks act as major diffuse phosphorus (P) sources at catchment scale. Furthermore, the study aimed at analyzing the impact of different factors influencing bank erosion and P loss such as stream order, anthropogenic disturbances, ...
