Soil carbon and nitrogen erosion in forested catchments: Implications for erosion-induced terrestrial carbon sequestration [PDF]

open access: yes, 2015
Lateral movement of organic matter (OM) due to erosion is now considered an important flux term in terrestrial carbon (C) and nitrogen (N) budgets, yet most published studies on the role of erosion focus on agricultural or grassland ecosystems.

A Comprehensive Review on Investigation of Sediment Erosion of Pelton Wheel Turbine

open access: yesPakistan 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 ...

A model for fluvial bedrock incision by impacting suspended and bed load sediment [PDF]

open access: yes, 2008
A mechanistic model is derived for the rate of fluvial erosion into bedrock by abrasion from uniform size particles that impact the bed during transport in both bed and suspended load.

Application of Gully and Rill Erosion Indicators for Estimating Soil Loss Using GIS Techniques [PDF]

open access: yesDesert, 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.

PHOTOSED—PHOTOgrammetric Sediment Erosion Detection

open access: yesGeosciences, 2018
This work presents a novel high-resolution photogrammetric measuring technique (PHOTOSED) to study in detail the erosion behavior of cohesive sediments, or cohesive/non-cohesive sediment mixtures.

Graffiti for science – erosion painting reveals spatially variable erosivity of sediment-laden flows [PDF]

open access: yesEarth 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.

Erosion and Sedimentation [PDF]

open access: yesEos, 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

THE EFFECT OF WATERSHED ENVIRONMENTAL CONDITIONS AND LANDUSE ON SEDIMENT YIELD IN ALO-POHU WATERSHED

open access: yesIndonesian 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-

On the stabilizing influence of silt on sand beds [PDF]

open access: yes, 2013
In marine environments, sediments from different sources are stirred and dispersed, generating beds that are composed of mixed and layered sediments of differing grain sizes.

Experimental study on sheet erosion process of loess and its suitability of hydraulic parameters on gentle slopes

open access: yesShui kexue jinzhan, 2021
In order to determine erosion-limited conditions and the suitability of hydraulic parameters in sheet erosion of loess gentle slope, simulated rainfall test was used in this study, under condition of 60 mm/h rainfall intensity, 3 slopes (7.5°, 10°, 15 ...
