“…In addition, sediment analysis represents a relevant task of lacustrine investigations, where freshwater allows for improved wave penetration and image resolution [259][260][261]. With respect to conventional underwater mapping methods, GPR represents a faster and more reliable solution, particularly in a shallow water context, capable of providing a continuous cross-section of the lake bottom and the underlying sediment column [262][263][264][265][266]. Waterborne GPR mapping of lakes has several objectives, including studies of sedimentation environments and stratigraphic boundaries [267,268], the estimation of a sedimentation rate and volume of lacustrine sediments [269], and the tracing of tectonic faults and displacements beneath the lake [270], improving the understanding of the evolution of water bodies at a local scale.…”

Thanks to its non-destructive, high-resolution imaging possibilities and its sensitivity to both conductive and dielectric subsurface structures, Ground-Penetrating Radar (GPR) has become a widely recognized near-surface geophysical tool, routinely adopted in a wide variety of disciplines. Since its first development almost 100 years ago, the domain in which the methodology has been successfully deployed has significantly expanded from ice sounding and environmental studies to precision agriculture and infrastructure monitoring. While such expansion has been clearly supported by the evolution of technology and electronics, the operating principles have always secured GPR a predominant position among alternative inspection approaches. The aim of this contribution is to provide a large-scale survey of the current areas where GPR has emerged as a valuable prospection methodology, highlighting the reasons for such prominence and, at the same time, to suggest where and how it could be enhanced even more.
