Comparative Study of a 1D and 2D Numerical Analysis Modelling a Water Flow at a River Confluence under Accidental High Waters
Journal Title: HIDRAULICA - Year 2018, Vol 0, Issue 4
Abstract
There are presented two numerical simulations – 1D and 2D – regarding the water flow on Timiş River in the Town of Caransebeş, Romania, at the confluence with its tributary Sebeş River. There was considered an accidental high waters wave following the synthetical configuration of a given significant hydrograph that happened from 4th to 11th of April 2000. The flow simulation by the two numerical models analysed by the help of HEC-RAS package aim to estimate the flow configuration, the velocities and levels developments, on a confluence river sector with specific bridge and protection structures. The analysis looks to establish some additional technical aspects regarding the flood defence of the urbanised major river plain or the streambed and framing embankments erosion protection.
