In this article a 2-dimentional model of shallow sea tomography is regarded for the joint reconstruction of waveguide parameters in a water layer and in a bottom using modes’ time delays as initial data. Linear approximation is used for the inversion of initial data and correction of the estimates is implemented in iteration cycle. The results of numerical simulation for the joint reconstruction of sound speed profile, flows and bottom properties by using the regarded scheme are presented.
