摘要：In Tunisia , espec ially in the Medjerda watershed the recurring of floods is becoming more frequent. The purpose is to improve the different methods of hydraulic modelling, mainly rega rding the floodplain modelling. Thus, we are interested in hydraulic modelling applied to the Medjerda R iver. Two types of models are examined in this paper; one - dimensional models using HEC RAS (1D) and MIKE 11 (1D), and a two - dimensional one using TELEMAC 2D. These m odels arecalibrated on data measured during the spectacular flood occurred in January 2003 in Tunisia; and a comparison of the simulation r esults of these 1D and 2D models isperformed. The objec tive of these compariso ns is to s howthe benefits and limitations of tested models in flood forecasting. The a nalysis of the results shows a good agreement between 1D and 2D models and that the reliability of results depends strongly on the accuracy of available data.
