Evaluating the importance of surface soil contributions to reservoir sediment in alpine environments: a combined modelling and fingerprinting approach in the Posets-Maladeta Natural Park [PDF]
Solid Earth, 2014 Soil in alpine environments plays a key role in the development of ecosystem services and in order to maintain and preserve this important resource, information is required on processes that lead to soil erosion.

A Comprehensive Review on Investigation of Sediment Erosion of Pelton Wheel Turbine
Pakistan Journal of Engineering & Technology, 2022 Hydro turbines installed at different hydropower plants face the issue of sediment erosion. Sediment erosion is an ambiguous phenomenon influenced by several parameters, including silt concentration, size, jet velocity, diameter, and fluid viscosity ...

Graffiti for science – erosion painting reveals spatially variable erosivity of sediment-laden flows [PDF]
Earth Surface Dynamics, 2016 Spatially distributed detection of bedrock erosion is a long-standing challenge. Here we show how the spatial distribution of surface erosion can be visualized and analysed by observing the erosion of paint from natural bedrock surfaces.

Application of Gully and Rill Erosion Indicators for Estimating Soil Loss Using GIS Techniques [PDF]
Desert, 2012 The problems of land degradation and soil loss are among the major problems of watersheds in Iran. For erosion andsediment estimation one can use statistical and empirical methods.

THE EFFECT OF WATERSHED ENVIRONMENTAL CONDITIONS AND LANDUSE ON SEDIMENT YIELD IN ALO-POHU WATERSHED
Indonesian Journal of Geography, 2013 The research carried out in alo-pohu watershed gorontalo province aims at identifying the effect of watershed conditions and land use on the amount sheet erosion, sediment yield and sediment delivery ratio. It is also intended to develop them in a spatio-

Erosion and Sedimentation [PDF]
Eos, Transactions American Geophysical Union, 1999 According to legend, a conversation that took place more than 70 years ago between Albert Einstein and his eldest son, Hans Albert Einstein, gives rise to the favorite anecdote of every scientist or engineer working in the field of sediment transport. During this conversation, Hans told his father of his intent to carry out research on the mechanics of

Sediment Erosion Generated by a Coandă-Effect-Based Polymetallic-Nodule Collector
Journal of Marine Science and Engineering, 2023 To date, hydraulic collection is the most widely considered technology in polymetallic-nodule mining, since there is no direct contact between hydraulic collectors and ocean floor.
