A common requirement of laboratory and field data collection is for automated data logging software to control instrumentation and report on the results. Large projects may require a range of different instrumentation each with its own preferred meth... Read More about Data Acquisition Software for Controlling Serial Ports with Cloud Data Storage.

Soil atmosphere interactions for analysing slopes in tropical soils (2014)
Conference Proceeding
Toll, D., Rahim, M. M., Karthikeyan, M., & Tsaparas, I. (2014). Soil atmosphere interactions for analysing slopes in tropical soils. In F. Oka, A. Murakami, R. Uzuoka, & S. Kimoto (Eds.), Computer Methods and Recent Advances in Geomechanics (1333-1338)

Modelling of soil-atmosphere interaction for slopes requires a proper understanding of the soil parameters (soil retention curve and the permeability function). This paper reports on numerical investigations of an instrumental residual soil slope in... Read More about Soil atmosphere interactions for analysing slopes in tropical soils.

Information Technology in Geo-Engineering (2014)
Book
Toll, D., Zhu, H., Osman, A., Coombs, W., Li, X., & Rouainia, M. (Eds.). (2014). Information Technology in Geo-Engineering. Netherlands: IOS Press

Information technology continues to evolve and remains central to all aspects of geo-engineering. Key issues are the effective use and re-use of data, particularly within Building Information Modelling (BIM) frameworks; the use of smart monitoring; a...

Interpretation of stresses and strains in unsaturated fine-grained soils (2014)
Conference Proceeding
Murray, E., Toll, D., & Sivakumar, V. (2014). Interpretation of stresses and strains in unsaturated fine-grained soils. In N. Khalili, A. Russell, & A. Khoshghalb (Eds.), Unsaturated Soils: Research & Applications (197-201)

The derivation of Eq. (1) relies on the soil particles and water phase combining and forming aggregates under equilibrium conditions. This may be shown to minimise the thermodynamic potential and is a requirement of equilibrium conditions. The equati...

Investigation of the directional dependence of soil resistivity in cracking clays (2014)
Conference Proceeding
Hassan, A., & Toll, D. (2014). Investigation of the directional dependence of soil resistivity in cracking clays. In N. Khalili, A. Russell, & A. Khoshghalb (Eds.), Unsaturated Soils: Research & Applications (137-142)

Electrical resistivity is a physical property that defines how a material resists the flow of electricity. The resistivity method is therefore based on the principle that the potential drop across a pair of electrode (P1 and P2) associated with DC or...

Handbook of Tropical Residual Soils Engineering (2012)
Book
Huat, B., Toll, D., & Prasad, A. (Eds.). (2012). Handbook of Tropical Residual Soils Engineering. London: Taylor and Francis Group. https://doi.org/10.1201/b12302

Residual soils are found in many parts of the world. Like other soils, they are used extensively in construction, either to build upon, or as construction material. They are formed when the rate of rock weathering is more rapid than transportation of... Read More about Handbook of Tropical Residual Soils Engineering.

The Behaviour of Unsaturated Soil (2012)
Book Chapter
Toll, D. (2012). The Behaviour of Unsaturated Soil. In B. Huat, D. Toll, & A. Prasad (Eds.), A Handbook of Tropical Residual Soil Engineering (117-145). London: Taylor and Francis. https://doi.org/10.1201/b12302-9

This chapter provides an overview of the important aspects of unsaturated soil behaviour that are of relevance for tropical residual soils. Many tropical soils exist in an unsaturated state due to soil water deficits induced by the tropical climate.... Read More about The Behaviour of Unsaturated Soil.

Advances in suction measurements using high suction tensiometers (2012)
