Özet

This study collected surface waves of alluvial deposits in Yeni and Karsiyaka settlement, Southern parts of Kumluca by using the multichannel analysis of surface waves method (MASW). MASW is an active-source technique requiring an impulsive signal, such as from a sledgehammer to generate surface waves. Shear-wave velocity structure is derived from the fundamental mode Rayleigh wave field generated by the source. Surface-waves, however, have dispersion property which means that different wavelength has different penetration depth and, therefore, propagates with different velocity. Therefore, by analyzing the dispersion of surface waves, one can obtain near-surface velocity profile. The purpose of these surveys was to map shear-velocity 1-D Vs maps. Alluvial deposits at this site consisted of a very heterogeneous mixture of gravel in a sand-and-clay matrix. Results from each survey were represented by 1-D Vs maps, showing soil characteristics.
