Floodplain Modeling Using HEC-RAS and MIKE11 Models
Journal Title: Journal of River Engineering - Year 2014, Vol 2, Issue 5
Abstract
A significant deficiency of most computer models used for stream floodplain analysis is that the locations of structures impacted by floodwaters, such as bridges, roads, and buildings, cannot be effectively compared to the floodplain location .In The different mathematical models, With the ability to perform hydrodynamic calculations because of using Different equations may not obtain the same results, Therefore , In this paper the Results of flood plain zone are compared with the two hydraulic models, MIKE11 and HEC-RAS. Initially The analysis of hydraulic flood is performed with entry data geometric cross sections, boundary conditions and initial data after calibration then the results of the model that consists of flood zones as layers of data transfer to ARCVIEW software and overlay with topographic maps 1/2500 national mapping agency. Finally, results are shown in flood zone maps for the HEC-RAS and MIKE11 models. When we compared the results of the two models, we found little difference between the models.
