Assessing the Effects of DEM Uncertainty on Erosion Rate Estimation in an Agricultural Field [PDF]
, 2012 The slope length and steepness (LS) factor is one of the factors in the Revised Universal Soil Loss Equation (RUSLE) needed to estimate average annual erosion rate. The LS factor is often derived from digital elevation models (DEM).

Increased erosion rates due to uplift and glacial erosion [PDF]
Eos, Transactions American Geophysical Union, 2014 Around the world, geologists have found overwhelming evidence that starting about 5 million years ago, erosion rates began to increase. Geoscientists, puzzled about the cause of this increase, are specifically debating whether it is due to climate change or an increase in rock uplift as the Earth's topography evolved.

Modeling sunspot and starspot decay by turbulent erosion [PDF]
, 2015 Disintegration of sunspots (and starspots) by fluxtube erosion, originally proposed by Simon and Leighton, is considered. A moving boundary problem is formulated for a nonlinear diffusion equation that describes the sunspot magnetic field profile ...
