Project is dedicated to mathematical modelling of natural processes, specifically to development of an one-dimensional uncoupled model for fractional sediment transport computations in natural watercourses. The proposed use of the model will be for simulating sediment transport under laboratory conditions, as well as for computing sediment budgets at basin scale or for forecasting temporal evolution of natural watercourses. First step in the model development is the choice of the appropriate fractional sediment transport model. Second important step in the model development is the integration of the appropriate equations of fluvial abrasion. Third important step in the model development is the integration of appropriate equations of selective transport, using the Hirano''s principle of an exchange layer. In this part of the development, the main aim is to take into account different modes of sediment transport, and to develop new hiding functions, which will be adequate to use the model for very different sediment transport conditions (aggradation, degradation, combination of aggradation and degradation, bimodal sediment mixture of gravel and sand). The model development ends with the integration of an at least simple equation of interactions between turbulent flow and resting or moving sediment grains.
