Effects of sand content and grain size on the compression behaviour of clayey sand

Frontiers in Built Environment
While extensive studies have been conducted on the compressibility of clay and sand, soils commonly encountered in natural environments or hydraulic reclamation projects are often gap-graded mixtures of coarse and fine particles, such as sand-clay or ...

Modeling of transpiration reduction in van Genuchten-Mualem type soils

, 2009
We derive an analytic expression for the matric flux potential (M) for van Genuchten-Mualem (VGM) type soils which can also be written in terms of a converging infinite series.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

Archaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Geotechnical viability of sand, cement, and binary stabilisation of soils in the western Niger Delta; An example of Warri City, Southern Nigeria

Journal of the Geological Survey of Brazil
The pavement performance of superficial soils in southern Nigeria is in decline, most notably due to the use of inferior pavement materials and poor soil conditions.

Effects of blown sand and soil properties on the abrasion rate of compacted soil

Geoderma
Abrasion caused by blown sand is an important process for compacted soils in grasslands. The abrasion rate is affected by a combination of the blown sand intensity and the properties of the underlying soil, but there is a paucity of relevant studies of the simultaneous effects of these factors, especially quantitative ones.

Leveraging Big Multitemporal Multisource Satellite Data and Artificial Intelligence for the Detection of Complex and Invisible Features: The Case of Extensive Irrigation Mapping

Archaeological Prospection, EarlyView.
ABSTRACT The detection of buried or obscured archaeological features remains a central challenge in landscape archaeology, particularly in the irrigated floodplains of Mesopotamia where levees and canals formed the basis of complex agrarian systems. This study presents a deep learning–based approach for the large‐scale, automated detection of ancient ...

A Sand-Spreader used for the Reconstitution of Granular Soil Models

Soils and Foundations, 1991
If one is to deal with experimental analysis of soil-foundation interactions, the first problem to consider is that of reconstituting soil models. This paper presents the results obtained by using a sand-spreader which was designed and built by the author for this purpose. The paper also looks at design criteria and the calibration of the assembly. The
