In this project, we investigate the transformation of Fe during granite weathering and early soil development in the forefield of a retreating glacier (Damma glacier, Central Aare massive, Switzerland). This work is integrated in a multidisciplinary project on the links between climate change, rock weathering, soil formation, and ecosystem evolution. Fe is an essential nutrient and its release from weathering rock is a key factor in initial ...

We propose a new fluid control technique that uses scale-dependent force control to preserve small-scale fluid detail. Control particles define local force fields and can be generated automatically from either a physical simulation or a sequence of target shapes. We use a multi-scale decomposition of the velocity field and apply control forces only to the coarse-scale components of the flow. Small-scale detail is thus preserved in a natural ...
