For tokamak plasmas, transport calculations are usually done by solving the 1-D radial transport equations coupled with the equations governing the 2-D MHD equilibrium. In this thesis, fast alternatives for this computationally expensive 2-D step are investigated. Two options are investigated. The first option is to use numerical fits to find an analytic relation between a set of indicators and a set of 1-D profiles, which describe the equilibrium. The second option that was investigated, is to use a specific method for solving the inverse equilibrium problem, called the contour dynamics method.
