Comparisons of local infiltration-excess, overland flow and associated erosion behaviour with river behaviour at the catchment scale
overland flow erosion catchment scale
2015/1/4
Modeling overland flow and erosional behaviour is a very important scientific task today to prevent environmental impacts from human activities as well as physical disasters such as floods and deserti...
A Spatial Technique for Estimating Streambank Erosion Based On Watershed Characteristics
watershed modeling streambank erosion sediment transport
2015/1/4
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...
Assessment of the Impact pf Mining on Agricultural Land using Erosion-Deposition Model and Space Borne Multispectral Data
Erosion-Deposition Model Space Borne Multispectral Data
2015/1/4
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 ...
Erosion rates deduced from seasonal mass balance along the upper Urumqi River in Tianshan
Erosion rates deduced seasonal mass balance Urumqi River in Tianshan
2014/12/31
We report measurements performed during two complete flow seasons on the Urumqi River, a proglacial mountain stream in the northeastern flank of the Tianshan, an active mountain range in Central Asia....

River Migration banks failure paradigm shift mitigation of disasters
2014/11/26
The creation of regional imbalance, inequalities and differentiation in India, starts with the
physiographic element and ends with economic, and socio-cultural parameters of the
inhabitants/popula...
Determination of erosion surfaces and stages of evolution of Sangra drainage basin in Giridih district, Jharkhand, India
Surface drainage networks GIS Areal and linear properties Area-altitudinal relationship Erosional surface Stages of evolution PCA
2014/11/26
A major emphasis in geomorphology over the past several decades has been on the
development of quantitative physiographic methods to describe the evolution and behavior of
surface drainage network...
Trends analysis of river bank erosion at Chandpur, Bangladesh: A remote sensing and GIS approach
Riverbank erosion Channel shifting Remote sensing GIS Bangladesh
2014/11/24
Bangladesh which is mainly formed by alluvial deposits faces riverbank erosion very often
due to regular shifting of river channels. The present study has undertaken to study the trends
of riverba...
NPS Assessment Model: An Example of AGNPS Application for Watershed Erosion and Phosphorus Sedimentation
Watershed AGNPS model Phosphorus Sedimentation
2014/11/12
AGNPS, which is an agricultural non-point source pollution model, was used in combination with
GIS tools to assess the feasibility of water quality effluent trading for phosphorus, in Morrow Lake
su...

2014/4/24
In this work a detailed TLS survey was carried out in summer 2012, in the Conero Regional Park (Marche, province of Ancona),
along the “spiaggia San Michele” and “spiaggia Sassi Neri”. These areas p...
Sediment erosion revealed by study of Cs isotopes derived from the Fukushima Dai-ichi nuclear power plant accident
Fukushima Dai-ichi nuclear power plant accident Cs isotopes erosion Vietnam mega-delta
2017/4/11
Deltaic sediments of the Mekong River delta sampled from a tidal beach in Vietnam during the wet season (late
October 2011) showed strong 137Cs and 134Cs activities reflecting radionuclides released ...
Growth and form of the mound in Gale Crater, Mars: Slope wind enhanced erosion and transport
Growth and form of the mound Gale Crater Mars Slope wind enhanced erosion transport
2014/4/8
Ancient sediments provide archives of climate and habitability on Mars. Gale Crater, the landing site for the Mars Science Laboratory (MSL), hosts a 5-km-high sedimentary mound (Mount Sharp/Aeolis Mon...
Deciphering boulder mobility and erosion from cosmogenic nuclide exposure dating
Deciphering boulder mobility erosion from cosmogenic nuclide exposure dating
2014/4/8
Large boulders are prominent features in many geomorphic systems and are frequently targeted for cosmogenic exposure dating. Presently, there are little data or theory predicting exposure age, erosion...
GIS-Based Model to Assess Erosion Sensitivity in Northern Morocco. Laou Watershed Case Study

This application on the Laou watershed represents the first part of study results that concerns the development of a model for mapping soil susceptibility at a regional scale in northern Morocco using...
Using hilltop curvature to derive the spatial distribution of erosion rates
Using hilltop curvature derive the spatial distribution erosion rates
2014/5/20
Erosion rates dictate the morphology of landscapes, and therefore quantifying them is a critical part of many geomorphic studies. Methods to directly measure erosion rates are expensive and time consu...
