[06/24] Professor David Toll, Co-Director of IHRR, is co-author of “Soil–Water Retention Curve Prediction for Compacted London Clay Subjected to Moisture Cycles” published in Geotechnical & Geological Engineering
A new article has been published in the journal Geotechnical & Geological Engineering by Dr Ana Sofia Dias (Mott McDonald, previously Department of Engineering, Durham University), Professor Paul Hughes (Department of Engineering, Durham University) and Professor David Toll (Co-Director of the Institute of Hazard, Risk and Resilience (IHRR), Durham University).
The paper is an output from the EPSRC-funded ACHILLES project. It studies the evolution of the hydraulic properties of a high plasticity clay (London Clay) when subjected to cycles of wetting and drying. The soil–water retention curve (SWRC) is observed to change with environmental cycles and a new method is presented for predicting these changes based on the starting conditions for each cycle. This model allows the prediction of this evolution for modelling of infrastructure earthworks over the years, when subject to changing climatic conditions. The article relates to IHRR’s research in climate resilience.
