The aim of this work is to evaluate the possibilities, shortcomings of the current level of knowledge solving the qualitative problems of surface streams, with particular attention to the hydrodynamic approach of the dispersion solution in the surface streams and to the analysis of the available dispersion models. The result of the work is to analyse the results of numerical simulations under the same conditions on the simulated streams using 1D and 2D models, applying different numerical schemes, methods and different dispersion rates, as well as analysing the results of numerical simulations in different model situations on flow (flow rates, maximum flow rates, different types of outlets), influence of vegetation growth in stream, influence of different singularities (weirs, reservoirs, flow barriers, etc.) on the dispersion process.
Part of the work may also include determining the location of the pollution discharge (inverse - localization task). It is a task where the time courses of the pollutant concentration in the cross-flow profile are known, but the pollutant discharge point is not known.
