Tunnel valleys are large, elongate and irregular depressions cut beneath the margin of
former ice sheets. They are generally believed to play a substantial role for the entire …

This paper presents an overview of the strengths and limitations of existing and emerging
geophysical tools for landform studies. The objectives are to discuss recent technical …

Buried valleys are underground structures typical for areas affected by glaciations.
Especially when the glaciers met poorly consolidated ground, ie in sedimentary basins …

A meaningful interpretation of geophysical measurements requires an assessment of the
space of models that are consistent with the data, rather than just a single,'best'model which …

Buried tunnel valleys are common features in formerly glaciated areas, and where present,
they are very important for the groundwater recharge and flow. Delineation of the structures …

Two different airborne electromagnetic methods were applied in the same area: the
frequency-domain helicopter-borne electromagnetic (HEM) system operated by the Federal …

Repeat frequency-domain electromagnetic (FDEM) surveys have been acquired over
agricultural fields in the Powder River Basin (PRB), Wyoming, where subsurface drip …

Saltwater intrusion in coastal aquifers depends on the distribution of hydraulic properties, on
the climate, and on human interference such as land reclamation. In order to analyze the key …

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 …

Sediments deposited by glacial meltwaters (for example, ice‐contact delta deposits) form
permeable packages in the subsurface that can act as reservoirs for both water and …
