Adaptive remeshing in CFD is one of the main strategies for optimizing the use of computational resources and reducing simulation costs. This methodology renders specially valuable when studying fluviomorphological processes in natural environments, where the time and space scales set a constant challenge for the simulation. The ability to capture phenomenons that evolve through decades confers this techniques many qualitative and quantitative advantages. In this paper we describe the design and implementation of an automatic and adaptive mesh refinement algorithm for the software package openTelemac. We present the general system operation, the remeshing criteria and the geometric algorithms applied. A laboratory channel experiment, with abundant empirical data, was used to validate the model.
