“…It is 90 m long, 6 m high, has a 29 m base width and a 5 m wide crest with 1 in 2 slopes on the flanks. The embankment was constructed in 2005 in four main 18 m-long sections, with the two inner-most sections constructed according to Highways Agency specifications using 0.3 m lifts and 18 passes of a 7.3 tonne self-propelled smooth drum vibrating roller [14,15,[20][21][22]. These have been termed the 'well compacted panels' and simulate new-build highway embankments (Panels B and C in Fig.…”

“…We provide two case histories: firstly, from the BIONICS research embankment, Nafferton Farm, Northumberland, UK [14,21] constructed using varying amounts of compaction in 2005 from sandy, silty clay derived from partially sorted Durham Till; which includes identification of individual lifts from 2D resistivity sections across the embankment transect; and secondly, from an embankment along the former Great Central Railway near East Leake, Nottingham, UK [2,17,19] constructed via end-tipping of materials derived from the East Leake Tunnel cutting to the south; which includes identification of fill regime changes in a 2D resistivity section along the axis of the embankment, dynamic, seasonal wetting and drying fronts moving through a 2D transect of the embankment and a demonstration of the potential application of 3D volumetric images of moisture movement and geotechnical property visualisation for planning maintenance. Finally, these case histories provide the context for a broad discussion relating to the foundation for new risk-based asset management practices incorporating automated, electrical imaging technologies into early intervention decision processes, such as proactive drainage planning.…”

“…Many studies can be found in the literature that investigated the changes in stresses and stiffness of soil due to interactions that happen at the soil-vegetation-atmosphere interface [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Most of these studies focused on the pore water pressure cycles and related changes in soil strength and stiffness.…”

Expansive soils change volume due to changes in moisture content, which results in ground movement. Lightweight shallow-depth structures such as pavements, residential footings, and pipelines can suffer distress as they face additional stresses from the moving ground. The soil reactivity (the ability of soil to expand or contract due to change in moisture content) and the interactions at the soil-atmosphere-vegetation boundary are two of the major contributing factors to the ground movement. The current methodology used in design to account for ground movement is based on limited field and laboratory observations. Aiming at a better understanding of the interaction at the soil-atmosphere-vegetation boundary and its correlation with ground movement, this paper presents results from a field study. The research site was located in a semi-arid climate area and consisted of moderately to highly reactive clay soils. Part of the site was vegetated with mature trees, and part was occupied by grass. The order of 10 s of mm difference was observed in the magnitude of movement across the site owing to site soil variability as well as differences in vegetation. The areas with large trees showed relatively lower ground movement over the study period compared to the area occupied by grass, which was attributed to the microclimate created by the tree canopy and the already established deeper drying of the soil near the trees.

Ongoing climate change is now 'reasonably foreseeable' (see e.g. Firth and Colley 2006) and any uncertainty associated with the forecasts can no longer be used as an excuse to ignore the problem (e.g. Grossman 2003;Perroy 2006; Metcalf et al. 2009; Willows and Connell 2003). Failure to take account of the potential adverse effects of climate change on the stability of landscapes will carry additional financial risk (ABI 2009, Stern 2007, for example when inappropriate design, operation and maintenance strategies in undulating landscapes and earthworks continue to be applied (Dijkstra and Dixon 2007). Adaptation to forecasted changes in climate conditions is now key and this requires upgrading the knowledge base and slope instability modelling capability (Derbyshire et al. 2001; Dixon et al. , 2008 Glendinning et al. 2008)).This realisation has led to increasing pressures to take action and gain the necessary knowledge that would enable a more effective adaptation to the potentially adverse consequences of climate change, impacting natural and constructed (engineered) slopes and affecting both first-time and reactivated failures. This has been supported by targeted funding from the Engineering and Physical Sciences Research Council (EPSRC) in the UK for research into the implications of climate change (Building Dijkstra, T.A. & Dixon, N. (2010). Climate change and slope stability: Challenges and approaches. Quarterly Journal of Engineering Geology and Hydrogeology, 43, 4, 371-385. This paper briefly introduces the impacts of slope instability and the context of climate change forecasting. This is followed by a discussion of the current status of the forecasting capability with respect to responses of slope stability to climate change drivers. This discussion is an attempt to capture the outcomes of the workshops and symposium organised as part of the CLIFFS network, It is hoped that the issues raised will serve as an opportunity to engage in further discussions and research efforts that ultimately should lead to better slope instability process models and a more successful integration of these models with climate change forecasts (in particular UKCP09).
