Abstract

The present research focuses on a systematic review of Hydrodynamic Models used during the fluvial, pluvial and coastal flood simulation under climate change scenarios worldwide. Research selection and retrieval criteria were defined, taking into account the thematic focus, which were critically evaluated. The selection of hydrodynamic models for flood modeling depends on key aspects such as, environmental and climatic conditions, behavior of variables in water bodies, and new parameters are included, which become key factor during the modeling. HEC-RAS and MIKEFLOOD are among the most widely used models, due to their capacity and efficiency in flood modeling and reflect accurate results. However, other models are used, which despite not being recognized, they have modeling capabilities and exhibit a solid vision about the coastal, pluvial and fluvial floods under the near future. They are the basis for decision making associated with climate adaptation and risk prevention. It is the first review that covers this horizon in flood hydrodynamic modelling, since there is no evidence of documentary exploration of the subject.
