Geophysical methods are becoming very popular day by day due to their faster and cheaper implementation and ability to provide continuous information of the underlying soil strata.
Geophysical methods can be used for detailed investigation of sites which can save huge amount of unnecessary cost by minimizing the number of surprises when project execution starts.
Mostly, these methods do not require any kind of borehole drilling.
The maximum benefit of geophysical methods can be attained if they are used in the early stage of the project for better planning of detailed site investigation and planning of project.
The important factors that need to be considered carefully before selecting a method or combination of methods.
The method or combination of methods best suited for a given problem depends on the kind of soil property contrast would be best suited to identify the soil layering information.
The properties which are identified by different geophysical methods are:
