“…Geoelectrical and EM methods, however, offer limited insights into the soil mechanical status. Soil mechanical properties (e.g., strength and elastic moduli) are better probed and characterized using shallow seismic methods (Donohue et al, ; Foti et al, ; Keller, Carizzoni, et al, ; Socco et al, ). The sensitivity of seismic measurements to the mechanical states of the soil and wave interactions with inclusions offer opportunities for detection of compacted layers, aggregation, and potentially large pores beyond what geoelectrical and EM methods provide.…”

“…Several studies have attempted to characterize soil compaction through effects of soil bulk density on changes in Direct Current‐resistivity (DC resistivity) (Besson et al, ), by studying reflections of electromagnetic (EM) waves from soil compacted layers using Ground‐Penetrating Radar (GPR) (André et al, ; Muñiz et al, ; Petersen et al, ; Wang et al, ) or by relating inferred seismic velocities to soil strength obtained from penetrometers (Donohue et al, ; Keller, Carizzoni, et al, ). The motivation of most of the mentioned studies is grounded in the knowledge of how geophysical properties (e.g., electrical resistivity, dielectric permittivity, and seismic velocities) respond to variations of soil bulk attributes (e.g., clay content, density, and saturation).…”

The growing interest in the maintenance of favorable soil structure is largely motivated by its central role in plant growth, soil ecological functioning, and impacts on surface water and energy fluxes. Soil structure pertains to the spatial arrangement of voids and solid constituents, their aggregation, and mechanical state. As a fragile product of soil biological activity that includes invisible ingredients (mechanical and ecological states), soil structure is difficult to define rigorously, and measurements of relevant metrics often rely on core samples or on episodic point measurements. The presence of soil structure has not yet been explicitly incorporated in climate and Earth systems models, partially due to incomplete methodological means to characterize it at relevant scales and to parameterize it in spatially extensive models. We seek to review the potential of harnessing geophysical methods to fill the scale gap in characterization of soil structure directly (via impact of soil pores, transport, and mechanical properties on geophysical signals) or indirectly by measurement of surrogate variables (wetness and rates of drainage). We review basic aspects of soil structure and challenges of characterization across spatial and temporal scales and how geophysical methods could be used for the task. Additionally, we propose the use of geophysical models, inversion techniques, and combination of geophysical methods for extracting soil structure information at previously unexplored spatial and temporal scales.

“…The contribution of the air component is negligible because of its very low density, but porosity and saturation exert very significant control over both bulk density and stiffness of soils and engineered fill (Donohue et al, 2013b;Gunn et al, 2003). Stiffness is defined as the ratio of stress to strain in material undergoing deformation.…”

Rapid, non-intrusive surface wave surveys provide depth profiles from which ground models can be generated for use in earthwork condition assessment. Stiffness throughout earthworks controls the behaviour under static and dynamic loads, and characterising heterogeneity is of interest in relation to the stability of engineered backfill and life-cycle deterioration in aged utility and transportation infrastructure. Continuous surface wave methods were used to identify interfaces between fine-and coarse-grained fill in an end-tipped embankment along the Great Central Railway in Nottinghamshire, UK. Multichannel analysis of surface wave (MASW) methods were used to characterise subsurface voiding in a canal embankment along the Knottingley and Goole canal near Eggborough, Yorkshire. MASW methods are currently being used to study extreme weather impacts on the stability of a highplasticity clay embankment along the Gloucestershire-Warwickshire railway near Laverton. Optimal results were obtained using equipment capable of generating and detecting over wide frequency ranges. Notation

“…The correlation observed between the experimental Rayleigh dispersion and the V S ground model estimated from Rayleigh dispersion inversion has confirmed these techniques are useful for evaluating the Vs ground profile. In agricultural, Donohue et al, [13] also explored the possibility of MASW for assessment of agricultural compaction in a field environment. The results show the significance difference in shear wave velocity between heavily compacted headland and uncompacted soil.…”

Abstract. Soil compaction plays an important role in every construction activities to reduce risks of any damage. Traditionally, methods of assessing compaction include field tests and invasive penetration tests for compacted areas have great limitations, which caused time-consuming in evaluating large areas. Thus, this study proposed the possibility of using non-invasive surface wave method like Multi-channel Analysis of Surface Wave (MASW) as a useful tool for assessing soil compaction. The aim of this study was to determine the shear wave velocity profiles and field density of compacted soils under varying compaction efforts by using MASW method. Pre and post compaction of MASW survey were conducted at Pauh Campus, UniMAP after applying rolling compaction with variation of passes (2, 6 and 10). Each seismic data was recorded by GEODE seismograph. Sand replacement test was conducted for each survey line to obtain the field density data. All seismic data were processed using SeisImager/SW software. The results show the shear wave velocity profiles increase with the number of passes from 0 to 6 passes, but decrease after 10 passes. This method could attract the interest of geotechnical community, as it can be an alternative tool to the standard test for assessing of soil compaction in the field operation.
