Calibração automática da plataforma MOHID empregando um método estocástico de otimização e dados reais de um evento climático extremo em Nova Friburgo‐RJ: parte 1 - preparação do modelo digital do terreno e aquisição dos dados experimentais de preci

This is the first of two complementary articles that deal with the implementation of an automatic calibration routine coupled to a simulation model of runoff and the flow of two urban watersheds, both located in the city of Nova Friburgo, State of Rio de Janeiro, Brazil. The models were built in the MOHID Waters Modelling System. This first part presents the methodology of the construction of the Digital Terrain Model-DTM and the drainage network of the studied watersheds, made in the MOHID platform, as well as the acquisition of actual rainfall data and water levels through the site of the Instituto Estadual do Ambiente-INEA. The results were compared with ArcMap software and showed a good agreement regarding the delimitation of watersheds and the drainage network.
