The present-day topography of the European Alps shows evidence of intense glacial reshaping. However, significant questions regarding Alpine landscape evolution during glaciations still persist. In this study, we focus on the Rhône valley (Swiss Alps), and use a numerical model to estimate patterns and magnitudes of glacial erosion. Comparing modeling results on a reconstructed pre-glacial topo...

Quantifying erosion rates and processes remains a central focus of studying the Earth’s surface. Measurement of in situ–produced cosmogenic radionuclides (CRNs) enables a level of quantifi cation that would otherwise be impossible or fraught with uncertainty and expense. Remarkable success stories punctuate the fi eld over the last decade as CRN-based methodologies are pushed to new limits. Inh...

We propose a computational framework and strategies for performing tasks necessary for evaluation and optimization of land use management within an advanced GIS modeling environment. Such tasks involve modeling of landscape processes, simulation of impact of human activities on these processes and optimization of preventive measures aimed at creating sustainable landscapes. A typical example of...

The hydrology of a river basin interacts with its geomorphic form. Despite significant advances in hydrological modeling, the dynamic interactions between geomorphic, hydrologic and ecological processes are not adequately captured at the basin scale. There is a need for advanced modeling tools that address both runoff and erosion prediction in sufficient spatial and temporal detail for explorin...

While noise is generally a nuisance in everyday life, noise can be especially useful for certain people. Procedural Content Generation (PCG) almost always uses some form of noise, and games especially are benefiting from noise. Games use noise to add realism to hand-crafted models, but realistic landscapes generated procedurally are finding greater use. This paper explains methods of procedural...

The recent modification of the Water Erosion Prediction Project (WEPP) model has improved its applicability to hydrology and erosion modeling in forest watersheds. To generate reliable topographic and hydrologic inputs for the WEPP model, carefully selecting digital elevation models (DEMs) with appropriate resolution and accuracy is essential because topography is a major factor controlling wat...

[1] The stream power erosion law, which describes the erosion rate as a function of channel discharge and gradient, has often been used for modeling landscape evolution in regions dominated by fluvial processes. However, most previous studies utilizing the stream power erosion law simply use drainage area as a surrogate for channel discharge. Despite its convenience this simplification has impo...
