Front of unimpeded infiltrated sand moving as sediment transport through immobile coarse gravel
(Taylor and Francis Ltd., 2018)
A simple model for the front of unimpeded infiltrated sand, moving as sediment transport through immobile coarse gravel particles is proposed. The theoretical celerity of the front computed by the model matched the celerity ...

Mixed sand and gravel beaches of Buenos Aires, Argentina: morphodynamics and stability
(Springer, 2021-08)
Coastal erosion is a critical problem that affects several countries around the World that would increase concerning the anthropogenic sea-level rise. Gravel beaches have proved to be more stable facing coastal erosion. ...
Settlement Comparison Research in Response to Gravel Columns with Concrete under a Distributed Vertical Dynamic Load
(Trans Tech Publications Ltd, 2022-01-01)
Currently there are different techniques of soil improvement. One of them is the gravel columns that is one of the most popular and profitable techniques for soil improvement. This method of breeding increases the physical ...
Static earth pressures on a pile supported excavation in Santiago gravel
(2019)
Concrete soldier piles anchored in multiple levels are the most common method for supporting deep excavations in gravel. Their static design is based on limit equilibrium principles, although these procedures were originally ...
Individuality matters for substrate-size preference in the Nile tilapia juveniles
(2018-10-02)
Preference tests have usually been used to identify nonhuman animal preferences for welfare purposes (environmental enrichment), but they are mostly at the group level—that is, group preferences for resources or environmental ...
Differences in Be-10 concentrations between river sand, gravel and pebbles along the western side of the central Andes
(Elsevier, 2015)
Cosmogenic nuclides in river sediment have been used to quantify catchment-mean erosion rates. Nevertheless, variable differences in Be-10 concentrations according to grain size have been reported. We analyzed these ...
Tailoring Of Wormlike Micelles As Hydrodynamic Drag Reducers For Gravel-pack In Oil Field Operations
(Elsevier Science BVAmsterdam, 2016)
Dissectd gravels of the río gravels of the río Copiapó valley and adjacent coastal area, Chile.
(Geological Survey Research, 1965)
La historia cenozoica de la zona se muestra en gran medida. los sedimentos y accidentes geográficos de grava de tierras altas, terrazas de arroyos, y depósitos de terrazas marinas. Upland Gravel probablemente fue deposición, ...
