    The theme of this paper was determine the shape of glacial valleys in the region between Palenica Bialczanska and Lysa Polana( Polish Tatra Mountains), using seismic methods. Seismic data have been analyzed from refraction profiling carried out in 2005 and 2009. Later data have been correlated with the seismic reflection data and on this basis was a partial model of glacial valley in this area. Also performed multi-channel analysis of surface waves (MASW) on one of the profiles on the basis of which specifies the quality of subsurface layers.

    The aim of Master thesis is algorithm analysis of static correction estimations using OMEGA2 seismic data processing system WesternGeco company for different seismic data. Data analysis were used from Murzuq basin and from Brzeszcz region. In order to estimate static correction REFRACTION_TOMO and EGRM algorithms were used. REFRACTION_TOMO is based on tomographic inversion of first-arrival traveltimes and EGRM is based on refraction first-break pick times. The final results are presented as stack sections and as source/detector static shifts.

    Wyznaczanie parametrów sprężystych warstw przypowierzchniowych na podstawie badań sejsmicznych w rejonie budowy drogi S3 w okolicach Starych Bogaczowic

    The aim of the thesis was determination of geotechnical parameters of rock masses for Road engineering near Stare Bogaczowice – where construction of two tunnels is planned. Near the planned tunnel’s localization seven geotechnical holes were bored and seismic refraction investigations were carried on. After processing of seismic data were made rock mass models (seismic layers) and parameters were calculated. In the thesis was discussed the correlation between geophysical results and geotechnical data. The rock mass were classified with its usability as a bedrock for the road engineering. The end of the thesis is an opinion about usefulness of geophysical methods to estimate a parameters of rock masses.
