O modelo de evolução da linha de costa LTC: Pressupostos, evolução, validação e aplicação

The numerical modelling of the shoreline evolution is very important to understand the complexity of the processes related to the dynamic variability of sandy beaches and to support coastal zone planning and management. There are several numerical models to evaluate shoreline changes, however the simplest and most used models are based in the one-line theory (Pelnard-Considère, 1956). LTC (Long-Term Configuration) numerical model, developed by Coelho (2005), is based in oneline theory and simulates medium to long-term coastal configuration evolution, considering the evaluation of natural and anthropogenic scenarios. LTC was developed in 2005 at Aveiro University and since then it was modified and improved in collaboration with the Faculty of Engineering of the University of Porto. Thus, this work aims to assemble the existing information about LTC model, namely, the model assumptions and correspondent validations, the model evolution and its application so far. It is intended that this work allows the former and the new users to understand and to apply the model.
