O článku:
In Tunisia especially in the Medjerda watershed the recurring of floods becoming more remarkable. In order
to limit this risk, several studies were performed to examine the Medjerda hydrodynamic. The analysis of results showed
that the recurrences of floods at the Medjerda watershed is strongly related to the sediment transport phenomena.
Initially, a one dimensional modelling was conducted in order to determine the sediment transport rate, and to visualize
the river morphological changes during major floods. In continuity of this work, we will consider a two-dimensional
model for predicting the amounts of materials transported by the Medjerda River. The goal is to visualize the Medjerda
behaviour during extreme events and morphological changes occurred following the passage of the spectacular flood of
January 2003. As a conclusion for this study, a comparative analysis was performed between 1D and 2D models results.
The objective of these comparisons is to visualize the benefits and limitations of tested models. The analysis of the
results demonstrate that 2D model is able to calculate the flow variation, sediment transport rates, and river
morphological changes during extreme events for complicated natural domains with high accuracy comparing with 1D
Model.
