A model for fluvial bedrock incision by impacting suspended and bed load sediment
A model for fluvial bedrock incision impacting suspended bed load sediment
2014/4/8
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. The erosion rat...

Proviacal?application construction stabilization sediment-based river flood dikes
2012/3/28
The needs to build a new dike as well as to renovate the existing one came up in the Czech Republic after the floods in 2002. The dike construction project has also opened some doors in related areas....
Reclamation of a Sandy Desert Through Floodwater Spreading: II. Characterization of Clay Minerals in the Watershed and the Freshly-Laid Sediment
The Agha Jari Formation Aquifer Management Erosion Gareh Bygone Plain Sedimentation
2011/11/11
The artificial recharge of groundwater (ARG), where practicable, is an easy and economical method for desertification control in the arid and semi-arid zones where overpumping has critically lowered t...
Clay-Mineral Provenance, Sediment Dispersal Patterns, and Mudrock Diagenesis in the Nankai Accretionary Prism, Southwest Japan
Clay mineralogy Diagenesis Mixed-layer illite/smectite Mudrock geochemistry Nankai Trough Shikoku Basin
2011/12/23
Abstract: Offscraped strata within the toe of Nankai accretionary prism display an overall facies pattern of thickening and coarsening upward. Detrital clay minerals within the Quaternary trench-wedge...

MINERALOGIC VARIATIONS IN A PLEISTOCENE HIGH-RESOLUTION EOLIAN RECORD FROM THE OWEN RIDGE, WESTERN ARABIAN SEA (SITE 722): IMPLICATIONS FOR SEDIMENT SOURCE CONDITIONS AND MONSOON HISTORY
MINERALOGIC VARIATIONS SOURCE CONDITIONS MONSOON HISTORY
2011/11/8
Bulk mineralogy of the terrigenous fraction of 99 samples from ODP Site 722 on the Owen Ridge, western Arabian Sea, has been determined by x-ray diffraction, using an internal standard method. The sam...
Optical Density of Vertisol Clay Suspensions in Relation to Sediment Volumes and Dithionite-Citrate-Bicarbonate-Extractable Iron
Beidellite Extractable Fe Fabric Optical density Tactoid Vertisol
2012/1/11
Clay fractions of eight vertisols and vertisolic soils from Israel were found to consist principally of a Fe-rich beidellite. Sediment volumes of Na-clay suspensions, obtained in measuring cylinders a...
Equilibration of Clays in Natural and Simulated Bottom-Sediment Environments
Alteration Bottom sediments Dissolution Illite Vermiculite
2011/11/22
Abstract: To identify mineral alterations which might occur in stream environments, predominantly illitic soil clays were equilibrated in bottom sediment environments under natural and laboratory cond...
Clay Minerals as Indicators of Sediment Source in Tidal Estuaries of Long Island Sound
Clay Sediment Sedimentation Soil
2012/2/10
Clay minerals were used as indicators for determining the source of sediment in recently dredged harbors along the north shore of Long Island Sound. Amount and characteristics of clay minerals in sedi...
Comparative Studies on Extraction of Sediment Interstitial Waters: Discussion and Comment on the Current State of Interstitial Water Studies
Comparative Studies Sediment Interstitial Waters
2012/2/15
The implication by Murthy and Ferrell (1972) that interstitial water studies are in a confused state is criticized on the basis that the authors have not drawn on a considerable body of data, especial...
