The rate of river migration affects the stability of Arctic infrastructure and communities1,2 and regulates the fluxes of carbon3,4, nutrients5 and sediment6,7 to the oceans. However, predicting how the pace of river migration will change in a warming Ar
The partial obstruction of the ditches should not be considered only in a negative light. In fact, the primary channel network also serves to capture the sediments, meaning that less eroded soil is carried downhill and the soil thus remains on the site (Figure 1). Results of plot studies ...
None of these indices has been found to describe dental erosion in such a way that they can be regarded as the 'gold standard' for measure- ment of erosion. A simple and standardized index that is suitable for assessment of erosion should ideally be (1) easily applica- ble in general ...
According to Shi, ”Beng“ refers to the erosion type in which collapse is an important force, and ”Gang“ refers to the geomorphic form produced, so Benggang thus has a double meaning of occurrence and morphology. Xu (1996) was the first to introduce the concept of a Benggang landform...
βcan be treated as a calibration factor with a physical meaning. However, for a first-order approximation, we set a median value ofβ = 0.6 for the fraction of plastic work dissipated as heat in dynamic deformation37,38, and assume the initial energy is partitioned equally between the...
their relationship that, according to outside sources, does not seem to be happening, and this perception negatively impacts their commitment.” This suggests that those with avoidant attachment, "see changes to who they are in a particularly negative light, even if they a...

The interrill erosion rate was predicted well by a simple power function of the flow velocity ( R 2 =0.88, NSE =0.88), although this relationship lacks clear physical meaning. We also found that the interrill erosion rate increased as a power function with the runoff depth, rainfall ...
Disadvantages are that (1) equilibrium theory assumes the storm to be of sufficient duration for the equilibrium to be reached, which is not always the case, (2) hydrodynamic conditions change during a storm, meaning the equilibrium profile changes with time as well, (3) the models are ...
We found a tendency for gains to be proportionally higher in the Alto Paraná and Northeast forests than in other regions of the Atlantic Forest (Fig.7). These areas are within the more fragmented and disturbed regions of this biodiversity hotspot, meaning that restoration efforts there would pro...
