This information, in turn,(More)
We propose a methodological tool for examining the layout and revealing the concealed characteristics of urban water supply systems (WSS). For this purpose, we use underground images obtained with ground penetrating radar (GPR) as a method that does not alter the system conditions and environmental characteristics (non-destructive methods). The study(More)
