Sediment storage by vegetation in steep bedrock landscapes: Theory, experiments, and implications for postfire sediment yield
Sediment storage by vegetation steep bedrock landscapes Theory experiments implications postfire sediment yield
2014/4/8
Mechanistic models for sediment transport on hillslopes are needed for applications ranging from landscape evolution to debris-flow hazards. Progress has been made for soil-mantled landscapes; however...
Lateral sediment sources and knickzones as controls on spatio-temporal variations of sediment transport in an Alpine river
Sediment transport Critical shear stress Return period floods Particle entrainment Basin hydrology Swiss Alps

2013/3/8
The textural and mineralogical characteristics of subsurface sediments along with Ground Penetrating Radar (GPR) data collected along the Western margin of India were used to understand the deposition...
Investigation of cesium adsorption on soil and sediment samples from Fukushima Prefecture by sequential extraction and EXAFS technique
cesium adsorption clay minerals sequential extraction extended X-ray absorption fine structure (EXAFS) Fukushima
2017/4/11
Previous studies have shown that radiocesium (mainly 137Cs) was retained at the very surface of soils in Fukushima
Prefecture. Clay minerals and micas are assumed as the main sorbents for cesium (Cs)...

eutrophic oligohaline lake ecosystem phytoplankton carotenoids sediment
2017/4/11
The historical trend of the concentrations of carotenoids originating from phytoplankton in sediment cores collected at
two sites in Lake Shinji, a eutrophic oligohaline lake was investigated to clar...
Osmium concentrations and 187Os/188Os ratios of three sediment reference materials
Os concentration Os isotope sediment reference material Geochemical Survey of Japan heterogeneous Os
2017/4/11
187Os/188Os ratios and osmium concentrations were analyzed in sedimentary reference materials JSd-3, JMS-1, and
JMS-2, issued by the Geological Survey of Japan, using the isotope dilution method with...
A physical model for seismic noise generation from sediment transport in rivers
physical model seismic noise generation sediment transport in rivers
2014/4/8
Measuring sediment flux in rivers remains a significant problem in studies of landscape evolution. Recent studies suggest that observations of seismic noise near rivers can help provide such measureme...
Spatial and temporal trends for water-fl ow velocity and bed-material sediment transport in the lower Mississippi River
Spatial and temporal trends water-fl ow velocity bed-material sediment transport the lower Mississippi River
2014/4/8
Where rivers near the coastline, the receiving basin begins to infl uence fl ow, and gradually varied, nonuniform fl ow conditions arise. The section of the river affected by nonuniform fl ow is typic...
Meiofauna enhances organic matter mineralization in soft sediment ecosystems
soft sediment ecosystems Meiofauna enhances
2014/4/4
We investigated the influence of meiofauna on the benthic decomposition of a radiolabeled diatom bloom by
measuring the production of 14

in a laboratory microcosm. Mineralization of the diatom ...
Toward Improving Prediction of Sediment Transport over Wave-Induced Ripples
Wave-Induced Ripples Analytical eddy viscosity formulation
2011/8/29
Sediment transport over wave-induced ripples is a very complex phenomenon where available models fail to provide accurate predictions. For coastal engineering applications, the 1-DV advection-diffusio...
Beach Morphology and Sediment Budget Variability Based on High Quality Digital Elevation Models Derived from Field Data Sets
Moroccan Coast Beach Change Wave Forcing Digital Elevation Model 3-D Approach
2013/3/6
The morphological and volumetric changes of a sandy beach were investigated through a series of two- monthly filed surveys carried out aver a 2-year period from April 2005 to January 2007. This paper ...
Proposed retrofit for sediment settling velocity tubes (SVTs)
sediment settling velocities sediment distribution
2017/4/12
In order to determine the distribution of sediments, bottom-withdrawal settling velocity tubes (SVTs) are used. This
technique is, for example, often applied in estuaries. Yet, these tubes have serio...
Long-term pigment dynamics and diatom survival in dark sediment
Long-term pigment dynamic dark sediment
2014/4/8
In order to investigate survival of diatoms and long-term pigment dynamics in dark sediment, we incubated
samples of homogenized, sieved, tidal-flat sediment for 1 yr in darkness. Microscopic observa...
