Abstract
Dune systems have a complex dynamics which is difficult to model purely physical due to the no linearity of the wind shear stress estimation, the complexity of the dune systems geomorphology and the difficult to obtain real world field data to test them. Cellular models offer an interesting alternative approach with simple data entry requirements and very good reproduction of dynamic processes observed in the real world. These models can be an useful tool in the study of the dynamics of the El Fangar spit dune system. The application of these models to the dune system data will help to predict morphological evolution, identify sediment sources and sinks, study the importance of formation factors and analyze possible future scenarios focused on climate change risk assessment. The actual cellular models had not been widely applied to real world dune systems so some improvements must to be taken into account in an attempt to approximate them more closely to complex real systems: integration of wind data as the driving force of the sand saltation process, introduce the possibility of study the system dynamics under a direction and velocity changing wind regime and couple a sand supply model to the dune dynamic model.
