[1] Erosion in the Himalaya is responsible for one of the greatest mass redistributions on Earth and has fueled models of feedback loops between climate and tectonics. Although the general trends of erosion across the Himalaya are reasonably well known, the relative importance of factors controlling erosion is less well constrained. Here we present 25 Be-derived catchment-averaged erosion rates...

Turbulent erosion has been proposed as a major mechanism for removing wintertime cold-air pools (CAPs) from basins and valleys. The time scales involved in this erosion process, which are of great interest for winter weather forecasting, have not been studied systematically in the past. In this short contribution, a semi-analytical model is developed to estimate the time required for the dissip...

The functional relationship between erosion rate and topography is central to understanding both controls on global sediment flux and the potential for feedback between tectonics, climate, and erosion in shaping topography. Analysis of a high-resolution (10-m-grid) DEM transect across the convergent orogen of the Olympic Mountains reveals a non-linear relation between long-term erosion rates an...

OBJECTIVES The aim of this study was to estimate the prevalence of dental erosion and to investigate possible associations among dental erosion and medical history, dietary and lifestyle habits in a sample of adolescents in Greece. STUDY DESIGN The study sample consisted of 770 adolescents, 374 boys and 396 girls aged 13 to 16 years. All individuals were clinically examined and answered quest...

land use optimization is one of the suitable methods for soil conservation. the present research with objective of land use optimization for soil erosion minimization and pure income maximization was conducted in the part of taleghan watershed which comprises 80427.23 ha in area. to achieve this propose, area, erosion rate and net income value of each land uses according to requiring standards ...

soil erosion in a given area depends on natural characteristics of the place as well as the rate of  human impact. in iran, the mediterranean precipitation regime and relatively high erosivity of rain, wide area of erodible soils/lithological formations, sparse natural vegetation in many regions and mountainous topography are main natural factors that affect soil erosion by water. accelerated s...

over the past decades, the fallout radionuclides 137cs, 210pbex and 7be are increasingly being used to quantify soil erosion and sedimentation rates. although studies using 137cs and to some extent 210pbex are now well-documented, there is a need for further work aimed at exploring the use of 7be, particularly in arid and semi-arid areas. investigating soil erosion processes occurring over shor...

The Double Asteroid Redirection Test (DART) spacecraft was developed to provide the first measurement for orbital deflection of an asteroid upon intentional impact. NEXT ion engine is part mission, on its maiden voyage. As pre-launch risk reduction, erosion characteristics extraction grid system were evaluated using laser measurements sputtered molybdenum atoms over envelope potential throttle ...
