TRANSIENT EROSION OF THE ULNAR STYLOID PROCESS
Rheumatology, 1991A patient with polyarthritis had radiographs of the wrists taken at presentation and again at 6 months. At presentation radiographs were normal, but repeat X-rays at 6 months showed complete erosion of both ulnar styloid processes. This did not correlate with the clinical picture of a mild synovitis.

Water erosion as a fractal growth process
Physical Review E, 1993The time evolution of river patterns and earth's relief is simulated on lattice by modeling the process of water erosion. Starting from a randomly perturbed surface, the river pattern and earth's relief develop simultaneously. The river pattern becomes stationary after all lakes have vanished.

PROCESS-DETERMINED COASTAL EROSION HAZARDS
Coastal Engineering 2008, 2009The management of coastal hazards is closely dependent on coastline retreat resulting from storm erosion, which is one of the most important coastal phenomena that needs to be accurately quantified. A rigorous albeit complex Joint Probability Method (JPM) for estimating storm erosion volumes proposed by Callaghan, et al.

Erosion of cohesive sediments as a rate process
Ocean Engineering, 1979Abstract The problems associated with the erosion of cohesive sediment in the marine environment are well recognized. However, the mechanisms of controlling erosion are not well understood. The research to be presented was directed at characterizing the erosion resistance of cohesive sediment through the application of rate process and double layer ...

This paper considers some Australian research on the various processes of erosion and deposition involved in net loss of soil in water erosion. Detachment of soil by rainfall is non-size-selective, and in the presence of the highly size-selective process of deposition, a sediment rich in fine sediment is initially produced by these processes.

Hydrology and Erosion Processes
2020A common theme throughout this book are the environmental and biological components commonly associated with soil health. The soil environment is not an isolated realm; soils develop with specific parent materials, climate, physiography, hydrologic regimes, soil flora, and a particular succession of plant species.

Soil erosion models can play a critical role in addressing problems associated with soil protection and conservation. They are used for assessment and inventory purposes when financial and time-costs of obtaining useful soil erosion measurements are prohibitive. They provide assessments of both on-site loss of topsoil and off-site delivery of sediments

Diagnostics for Erosion and Deposition Processes in Fusion Plasmas
Fusion Science and Technology, 2008An overview is given of the wide range of diagnostics that is providing valuable information on the interaction between plasma and the material wall in a fusion device. Of each technique, a brief description is given in combination with the main advantages and disadvantages for PSI research.

Erosive tooth wear is a two-stage process. In the first stage (erosion), acids derived mainly from dietary sources partially demineralise and soften tooth surfaces. In the second stage (wear), the weakened tooth surfaces are worn by intra-oral frictional forces.

Incorporating Crusting Processes in Erosion Models
1998In most soils, surface crusting strongly influences the infiltration and erosion processes, so there is a need to include crusting in infiltration and erosion modelling. The processes involved in surface crusting, however, are extremely dynamic and crust characteristics are often difficult to measure.
