If we could rewind the tape of species evolution around the world and play it forward over hundreds of millions of years to the present day, we would see biodiversity clustering around regions of tect...
Study demonstrates strong potential of seagrass to curb erosion（图）
strong potential seagrass curb erosion
2019/5/8
Most people's experience with seagrass, if any, amounts to little more than a tickle on their ankles while wading in shallow coastal waters. But it turns out that these ubiquitous plants, varieties of...

Through utilizing water flow monitoring, rock scratching, soil wood piles and radionuclide 137Cs tracing in the Longhe karst ecological experimental site (hereinafter referred to“Longhe site”), Pinggu...
Chemical weathering controls erosion rates in rivers
Chemical weathering controls erosion rates rivers
2016/4/14
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the r...
Historic 2013 Colorado Front Range storm accomplished up to 1,000 years of erosion,CU-Boulder study finds
2013 Colorado storm accomplished 1,000 years of erosion CU-Boulder
2015/8/27
The historic September 2013 storm that triggered widespread flooding across Colorado’s Front Range eroded the equivalent of hundreds, or even as much as 1,000 years worth of accumulated sediment from ...
Value Added Benefits of High Definition Surveying (Laser Scanning) in Contrast to In-Situ Surveying for Erosion of Hydrological Waterways
Laser Scanning waterway surveying
2015/8/14
The purpose of this paper is to depict and illustrate the benefits of High DefinitionSurveying (HDS) also known as 3-dimensional laser scanning, in contrast to traditional surveying methods, such as R...
In 2006, the fourth author of this paper proposed a graph-theoretic model of interface dynamics called competitive erosion. Each vertex of the graph is occupied by a particle that can be either red or...
Erosion Predictions by Empirical Models in a Mountainous Watershed in Nepal
Erosion Predictions Empirical Models Mountainous Watershed Nepal
2015/8/14
Soil erosion is a crucial problem in Nepal where more than 80% of the land area is mountainous. In this study, two commonly used empirical soil erosion models, Revised Universal Soil Loss Equation (RU...

MPSIAC Erosion Sediment Yield Iran
2015/8/11
Watershed degradation due to soil erosion and sedimentation is one of the major environmental problems in Iran. In addressing the issue, a study on the validity of an empirical model of Pacific South ...
Support Soil Conservation Practices by Identifying Critical Erosion Areas within an American Watershed Using the GIS-AGNPS Model
AGNPS C factor erosion GIS Iowa T value water quality modeling
2015/8/11
Eroded soil from overland is one of the major nonpoint pollution sources in many watersheds. The subsequent sediment not only reduces conveyance capacity of streams and usable storage volume of reserv...
Assessment of the Impact pf Mining on Agricultural Land using Erosion-Deposition Model and Space Borne Multispectral Data
Mining Agricultural Land Erosion-Deposition Model Space Borne Multispectral Data
2015/8/6
Since erosion of mine overburden and mine dump leads to its deposition down the slope in the catchment, an attempt was made to study the erosion-deposition pattern in a micro watershed in part of Goa ...
A Spatial Technique for Estimating Streambank Erosion Based On Watershed Characteristics
Geographic Information System GIS watershed modeling streambank erosion sediment transport
2015/8/6
A GIS-based technique was developed for estimating streambank erosion rates for more accurately predicting total sediment loads at the watershed scale without the use of detailed field data. This tech...
