O modelo Muskingum-Cunge-Todini em rios com planície de inundação

Abstract

This paper is the second of two papers in a series which analyzes and improves the Muskingum-Cunge-Todini (MCT) model. In the first paper the simplified stream flow model and HEC-RAS are compared. The volume error was analyzed. The current paper presents a modification in the MCT model to account for the flow in floodplain rivers, whose velocity in flooded areas is significantly lower than the velocity in the main channel. This paper also shows the volume conservation tests and analysis of DX to avoid volume errors and numerical stability problems. The results show that the improved MCT model is conservative regarding volume.
