The subject of the thesis is to compare layered model and tomographic model. These models are used for description of low velocity layer in seismic survey. The goal of the work was to find out the conditions whether to prefer tomographic model instead of layered model. Program Geostar was used for modelling of low velocity layer. This program is a part of software package produced by CGG Veritas company. Geostar is available at department of Applied Geophysics for study purposes. Four synthetic models were created for comparison of tomographic and layered models. Models of low velocity layer were computed for layered an tomographic model in Geostar environment. Original models were compared to created models. Accuracy was estimated on root mean square error and static correction which was exactly known. In all cases, layered model showed better results then tomographic model. 1
