Only for applications near the continental shelf and in presence of a strong, distinct stratification or buoyancy driven current, you may benefit from using a 3D modelling approach such as our MIKE 3 software. MIKE FLOOD is a computer program that simulates inundation for rivers, flood plains and urban drainage systems. MIKE 21 is an extremely powerful and efficient tool and has been used successfully in hundreds of coastal flooding studies for more than 35 years.
Mike 21 flood software#
This makes our MIKE 21, or alternatively MIKE FLOOD software the suitable choice. Traditionally, 2D models have been applied for coastal flooding studies, as the water column under such conditions often is well-mixed.

In order to take proper action to minimise both potential casualties and damages, access to the right tools is essential. The key issues in coastal flooding are often the maximum water depths, flood extent and timing of the flooding in affected areas. Also, in recent years the effects of climate change induced sea level raise create concern for increased flood risk along coastal areas worldwide. For installation, you need to have MIKE Zero 2014 64-bit on your PC. The points defining the cross sections must be given as j,k (grid) coordinates, and written in a text file as follows: -. Floodway delineation, zoning and hydrodynamic modelling for a section of the Drava River was carried out with MIKE 21 software at a one-time input flood. Tsunami waves created by underwater earthquakes can cause similar damage and casualties. A simple extension to the standard MIKE 21 Discharge Calculation tool that adds support for multiple cross sections. The findings of this study shed light on the Bow River flood modelling, which can guide flood management.Coastal flooding is typically the result of critical events, such as hurricanes or similar severe storm events that cause storm surges. MIKE FLOOD facilitates the dynamic interchange of flow between MIKE 21 and MU MOUSE. This confirms the necessity of an appropriate calibration of the generated numerical models. Results of statistical KS and ANOVA test analysis showed that the model predictions were sensitive to the horizontal eddy viscosity and the Manning roughness. However, considering the balance between the computational cost and the accuracy of the results, both models were capable to adequately replicate the hydrodynamics of the river during the 2013 flood. It was shown that Delft3D-Flow model may require higher grid cell resolution to result in comparably same depth-averaged velocities throughout the study area. The results of this study demonstrated that, with approximately the same averaged grid resolution, MIKE 21 FM resulted in more accurate results with a higher computational cost compared to the Delft3DFlow model. HYDRO River for rivers, MIKE+ for collection systems and MIKE 21 for 2D surface flow.

However, in the FM-model using the finite volume.
Mike 21 flood professional#
Performance of each model was evaluated by the available historical water levels. MIKE FLOOD is the unique toolbox for professional flood modellers. MIKE 21 SG utilises a rectangular grid where each cell has a (surface-)elevation and fluxes/discharge are calculated over the four cell-lines (right, upper, left, lower), and it is very straightforward to analyse and view the bottom elevations from the grid which are used in the simulation. MIKE 21FM employs unstructured triangular mesh while Delft3D-Flow model uses curvilinear structured grids. This study investigates the performance of Delft3D-Flow and MIKE 21 FM to simulate the hydrodynamics of the river during the 2013 flood. Channel banks were eroded at various locations, and large gravel bars formed, which could lead to water level changes and accordingly more flooding. Erosion and deposition processes were exacerbated by a catastrophic flood in 2013. Water Resources Integrated catchment hydrology.
Mike 21 flood plus#
This study aims at hydrodynamic modelling of Bow River, which passes through the City of Calgary, Canada. MIKE Animator Plus is a digital video production studio, which enables you to produce amazing 3D video presentations from simulation results from MIKE 21, MIKE 3, MIKE FLOOD and MIKE SHE.
