We present two case histories from different areas and geological settings in Canada where we have used a vibrating seismic source coupled to a landstreamer receiver array in hydrogeological investigations related to aquifers in glacial sediments. In Manitoba, our P‐wave seismic reflection profiles are used to provide an assessment of the subsurface architecture of buried valleys, estimate the thickness and properties of both the channel fill and the overlying sediments to depths of ~100 m and locate optimum sites for groundwater well placements. In eastern Ontario, we collected P‐ and S‐wave seismic reflection as well as electrical resistivity data to investigate buried esker aquifers. The geophysical data provide detailed high‐resolution information (to ~30 m depth) on the structure of the esker core and its overlying sand cover and on the thickness and variability of the overlying fine‐grained aquitard. The data presented in this paper demonstrate that shallow seismic reflection methods are very effective tools to explore, assess and evaluate groundwater reservoirs and resources. The recent advent of landstreamer receiver arrays, especially when coupled to a vibratory seismic source, makes these methods significantly more cost‐effective and efficient. We now routinely collect ~1000 records/day, or 1.5‐6 line‐km/day, using our Minivib/landstreamer data acquisition system. With this type of efficient data collection, it is anticipated that the use of shallow seismic reflection methods in hydrogeological prospecting will increase as groundwater and its protection become more valued by society.

“…In the last years the 3-D HRS method has also appeared (Bü ker et al, 1998). The HRS method is well suited to hydrogeological investigation in a stratified earth model (Meekes et al, 1990;Meekes and van Will, 1991;Whiteley et al, 1998;Bradford et al, 1998;and Liberty, 1998), due to the relatively high resolution and the capacity to explore very deep targets.…”

Electrical tomography, which gives good results even in fairly complex geological environments, has given a new lease of life to electrical methods in hydrogeological surveys. Nevertheless, a rapid decline in resolution with increasing depth remains the main problem of the electrical methods. In the Pannonian basin in Croatia, at a test area, combining both electrical tomography and seismic reflection methods provides data that better constrain the lithological and hydrogeological model of the subsurface.Electrical tomography revealed a rather thick packet of sediments with increased resistivity at depths of 40-100 m. Using the electrical forward modelling, the existence of two different hydrogeological models was shown. The first model presupposes a reasonably homogeneous packet of sandy clays or clayey sands, and the other model presupposes the alternation between layers of clays and sands. From the hydrogeological point of view, the second model is perspective, but unfortunately, the use of electrical tomography alone does not allow the ambiguity to be resolved. The separation of these two models became possible using seismic reflection. Three seismic environments were isolated from the seismic profile treated, and the strongest reflections were discovered in the first seismic environment, which covers the depths from 40 to 100 m. It was determined that the second model is more acceptable, because these reflections are caused by lithological changes, that is, the alternations of sands and clays. The interpretation is consistent with exploratory borehole data. The conclusion is that electrical tomography gives data concerning the sediment lithology up to depths of 40 m, but at greater depths combined interpretation of electrical and seismic data constrains the subsurface model better.

“…The USGS publication on refraction method by Haeni (1988) and the papers by Lankston (1990), Steeples and Miller (1990), Steeples (2005) and Pelton (2005) present the details of seismic refraction and reflection methods and their applications in groundwater and near-surface investigations. The reflection seismic is significantly useful to overcome this limitation, but at the same time it needs specific survey design and parameters and processing to remove the effect of near-surface heterogeneities (Meekes et al, 1990 andGruber andRieger, 2003). Applications for fracture and fault detection are outlined by Ernstson and Kirsch (2009).…”
