Webusing multichannel analysis of surface wave (MASW) to detect the near-surface cavities. The methods used in this study include interpreting dispersion curves and amplitude mapping of the multichannel analysis of surface wave technique and interpreting the delay in first arrivals of compressional waves. To test these methods, a WebIn the last step, a theoretical dispersion curve is calculated for a given layered subsurface model, which is defined by each layer’s thickness, density, P and S velocity values. hukuk rehberi
