Sand Liquefaction Phenomena During the Seismic Crisis of May 2012 in Emilia, Northern Italy
and boils composition Emilia Romagna earthquake
2018/6/13
In May 2012, the Emilia region of the Po Valley was struck by a seismic crisis with two major events of magnitude Mw 6.1 and Mw 5.9. The first event induced widespread sand blows formed along buried c...
The survey and mapping of sand-boil landforms related to the Emilia 2012 earthquakes:preliminary results
Geomorphology Sand boils Digital elevation model Liquefaction Earthquake Italy
2015/8/26
Sand boils, which are also known as sand blows or sand volcanoes, are among the most common superficial effects induced by high-magnitude earthquakes. These generally occur in or close to alluvial pla...
Assessing the Importance of Sand as a Source of Fecal Indicator Bacteria (Escherichia coli and Enterococcus)
Escherichia coli Enterococcus
2015/7/21
The purpose of this activity is for students to investigate water quality, and the factors that affect it, at a local beach. This is accomplished by (1) measuring concentrations of Escherichia coli an...
Shear band in sand with spatially varying density
Bifurcation Digital Image Correlation Heterogeneous sand Shear band Strain localization
2015/7/1
Bifurcation theory is often used to investigate the inception of a shear band in a homogeneously deforming body. The theory predicts conjugate shear bands that have the same likelihood of triggering. ...
RECONSTRUCTING PAST ANTARCTIC ICE FLOW PATHS IN THE ROSS EMBAYMENT, ANTARCTICA USING SAND PETROGRAPHY, PARTICLE SIZE AND DETRITAL ZIRCON PROVENANCE
Provenance Antarctica zircons Till
2015/1/16
Tills for this study were analyzed from sites in East Antarctica (EA), West Antarctica (WA) and along a transect in the Ross Sea. Particle size, sand petrography, and detrital zircons were used to pro...
SAND: An Additive for Stabilzation of Swelling Clay Soils
Clay Soils Bentonite Sand Swell Stabilization
2013/3/11
An experimental program carried out in this study seeks to understand the physical mechanisms of stabilization of an expansive soil by adding an inert material (sand) at various forms; mixing and inte...
Sedimentary structure of large sand dunes: examples from Dumont and Eureka dunes, California
Ground penetrating radar Geomorphology Wave propagation
2014/4/10
The current research presents ground penetrating radar images up to 30 m in depth of two large desert dunes in California, USA— a barchanoid ridge in the Dumont field and a linear dune in the Eureka e...

Tropical Clayey Sand Soil's Behaviour Analysis and Its Empirical Correlations via Geophysics Electrical Resistivity Method and Engineering Soil Characterizations
Empirical Correlations Regression Coefficient Resistivity Moisture Content Fluid Behaviours
2013/3/7
Soil is a heterogeneous medium which consist of liquid, solid, and gaseous phases. The solid and liquid phases play an essential role in soil spontaneous electrical phenomena and in behaviour of elect...

Geoelectrical Resistivity Seismic Refraction Soil's Behaviour Investigate Monitoring Period
2013/3/7
The geoelectrical resistivity and seismic refraction surveys which were used in this study on the test site, delivered a detailed image of the near-surface conditions in generally very good. Electrica...
Oedometric Test, Bauer's Law and the Micro-Macro Connection for a Dry Sand
Oedometric Test Micro-Macro Connection
2010/11/25
What is the relationship between the macroscopic parameters of the constitutive equation for a granular soil and the microscopic forces between grains? In order to investigate this connection.
Evidence of microbial activity in siderite and calcite deposits on gastropod shells in Pliocene sand and clay beds from Lipovljani,Croatia
concretions fresh water diagenesis iron bacteria calcite siderite Pliocene Slavonia Croatia
2009/12/8
Freshwater Pliocene sand and clays found near Lipovljani in western Slavonia, Croatia, contain gastropods preserved by diagenetic mineral incrustations of alternating calcite and siderite. The geochem...
Patch behaviour and predictability properties of modelled finite-amplitude sand ridges on the inner shelf
Patch behaviour predictability properties modelled finite-amplitude sand ridges inner shelf
2009/11/2
The long-term evolution of shoreface-connected sand ridges is investigated with a nonlinear spectral model which governs the dynamics of waves, currents, sediment transport and the bed level on the in...

Experimental and theoretical memory diffusion of water in sand
water sand basic equations fluid diffusion
2009/5/13
The basic equations used to study the fluid diffusion in porous media have been set by Fick and Darcy in the mid of the XIXth century but some data on the flow of fluids in rocks exhibit properties wh...
