ABSTRACT
This paper presents a 1-dimensional unsteady flow hydraulic model used for the simulation of flow in rivers: the MIKE 11 model from the Danish Hydraulic Institute (DHI). In this study, the hydraulic model uses flow and stage hydrographs in a time series format from field measurements. The approach for this model leads to unsteady flow simulations along stream channel reach. The study case applied to the model is the Argesel River in Romania. MIKE 11 – UHM (Unit Hydrograph) was used for the simulation of rainfall runoff process in the Argesel River catchment and MIKE 11 – HD was used to simulate the unsteady flow of the Argesel River. The study’s focus was the development of a MIKE 11 model based on surveyed, stream cross-section data. The results of this study explain that the model gives a good simulation of the flow according to a comparison between the estimated and observed stage hydrograph.
