dc.description.abstractThe use of geophysical methods, particularly ground-penetrating radar (GPR), in the environmental sites has taken very important approximation in locating potential environmental hazards such as landslides and cavities. Generally, slices of a three-dimensional (3D) GPR data set can be used to monitor changes in the surface locations and depth of the environmental hazards through the iterative slices. The aim of this study is to introduce volume imaging of subsurface cavities with a transparent half bird's-eye view within a 3D data set. Transparency is obtained by a constructed opaque function of the amplitude-colour range. The half bird's-eye view is achieved by observing angles of the x-, y-and z-directions to the 3D block. A GPR study was conducted at a reservoir area (696m x 100 m) in Akkopru dam and hydroelectric power station in Mugla (Turkey) to determine the existence and abundance of karstic cavities. The study revealed the presence of 283 cavities of various size and depth. Borehole data encouraged the results with given depths.
