Résumé
The knowledge of large wood (LW) dynamics regarding factors controlling wood transport, preferential depositional sites and the timing and duration of wood flux, is crucial for the maintenance of a good ecological status of rivers and for the management of wood-related potential hazards. Besides field surveys, tracking experiments or physical modelling, numerical models represent an alternative and complementary approach to explore LW dynamics, to test hypotheses and to run scenarios. We used a 2D numerical model which simulates the transport of large wood together with flow dynamics. The model is able to predict and simulate wood transport and deposition, and reproduces interactions between wood, channel bed, floodplain surface and infrastructures. We applied this model combined with direct field observations to explore main factors controlling large wood dynamics in the Czarny Dunajec River in Poland. We simulated different types of logs under different flood magnitude scenarios (steady and unsteady flow conditions) to analyse wood transport, deposition and remobilization in two contrasting river morphologies. We summarized in this chapter the main outcomes from this work. Results illustrate that a wide range of quantitative information about LW transport and deposition can be obtained from the use of numerical modelling together with the proper assessment of inlet and boundary conditions and validation based on field data.
