Abstract

This is the second of two complementary articles that deal with the implementation of an automatic calibration routine coupled to a simulation model of runoff and hydraulic behavior of the drainage system of a watershed during flood events, built in the water Modeling System MOdelo HIDrodinâmico (MOHID). As a case study two watersheds located in the city of Nova Friburgo, State of Rio de Janeiro were analysed. This second article discusses the pertinent aspects related to the inverse problem technique and the coupling of MOHID platform to Luus‐Jaakola optimization method, aiming to estimate some of the key parameters required for modeling the drainage in watersheds and the flow in channels. The adopted strategy proved very effective in its ability to estimate the parameters which led to a satisfactory agreement between simulated and observed water levels at stations located along the studied rivers.
