MIKE FLOOD
Release Note - 2011
Welcome to MIKE FLOOD Release 2011.
MIKE FLOOD is a dynamically linked one-dimensional and two-dimensional flood modelling package. MIKE FLOOD is the integrated flood modelling package for rivers (MIKE 11), overland flow (MIKE 21) and urban drainage (MIKE URBAN's MOUSE engine). This combination ensures a maximum of flexibility by allowing users to model some areas in 2D detail, while other areas can be modelled in 1D.

- Alternatively, the license file can simply be copied from the supply medium (attachment to e-mail from DHI or CD/DVD) in \Program Files\DHI\2011\License or Program Files (x86)\DHI\2011\License.
Product Invocation^ top
To start MIKE Flood go to Start -> Programs -> MIKE BY DHI 2011-> MIKE FLOOD.
Starting MIKE Flood without a DHI configured Software Key and valid license files causes the program to run in Demo mode. If this happens, a message box will inform you during program initialisation. Running in Demo mode, MIKE Flood supplies full access to all editors, input files and editing facilities. However, restrictions apply on which set-ups that can actually be executed as a model simulation.

New features^ top
Every new release of MIKE FLOOD consists of new modules, new features and/or corrections to problems or significant inconsistencies discovered in previous releases. Please find short descriptions of the most significant news in Release 2011 below.
MIKE Zero
- MIKE to Google Earth: A new tool that can be used in conjunction with the Google Earth Viewer to display contour maps of georeferenced dfs2 data files. This tool replaces the older GE Plugin and has additional user-defined variables such as color scaling, datum shift and image size.
- Climate Change: A new tool that can generate future climate change scenarios based on existing setups.
- MIKE Zero Toolbox - new Time Series Batch Conversion tool: Batch conversion between dfs0, ASCII and EXCEL files
MIKE FLOOD
- Enlarged Graphical View.
A new page for linkage files specification and a re-organized Links definition page has resulted in a significantly enlarger Graphical View in the GUI.- Direct access to River Cross sections and 2D Bathymetry from Graphical View.
The context sensitive pop-up menu in the Graphical View includes options for opening cross section editor and bathymetry editors.- Export linked MIKE 21 cells to dfs2-file
Linked MIKE 21 cells in some or all links can be exported to a grid-file (dfs2). This feature offers an easy possibility for specifying MIKE 21 parameters in linked grid cells - or eventually to use the exported grid file as a selection file for refinements in the bathymetry (feature only available for coupling to cartesian version of MIKE 21).- New feature for user-defined 'Defult Values' of all link-type variables
- New feature for 'bulk-editing' of parameter-values.
This feature allows for a change of values of one or more link-parameters in either all links or a number of user-selected links in one operation.- String search in all Linkage parameter pages are now available
- New Link Options: Side Structures
Side Structure in a MIKE 11 model can be linked directly to MIKE 21 through MIKE FLOOD.- New feature for Lateral Links: Time-dependent levees.
A feature for applying time depending levee heights during MIKE FLOOD simulation is now available through the use of a dfs1-file to represent a dynamic change of levee height along lateral link reaches.- Multi-core version of MIKE 21 Cartesian grid version => MIKE FLOOD Performance improvements
The MIKE 21 development for Release 2011 includes 64-bit memory handling and multi-core processing, which will also have a significant impact on the MIKE FLOOD performance. Faster simulations is therefore to be expected when running simulations on a multi-core PC compared to previous releases.- The option for generating the Lateral Link levee height information file; 'MFLateral.txt', has been slightly improved such that the file is now always created and additionally, the content is saved directly to a xns11-file (hence, no manual conversion work is required longer)
- Additional results output in MIKE 11 results.
Lateral link flows as saved in the MIKE 11 additional result file now includes lateral flow divided into spilling to the right side and left side respectively.Known Defects & Workarounds^ top

Fixed
MIKE FLOOD Service Pack 4, June 2011^ top
Module/Type Error/Inconvenience/New Feature Remarks M21-M11 coupling, Lateral Link The 'Semi-Implicit coupling solution' introduced for lateral links in Release 2011 has proven to fail in some models, which were running without problems in the previous release.
An error has been located in the generation and properties of link structures along the lateral link for the new method, and an unrealistic linkage flow could be calculated.The correction could have a significant impact on some models when comparing SP4-results with results generated in Release 2011 prior to SP4.
However, SP4 corrects an error and must be applied.
Backward compatibility with Release 2009 results can be obtained by changing the MIKE11.Ini variable 'MF_semi_implicit'.
(Default = ON, can be changed to OFF)MIKE 11 Control structures Initial water level and maximum speed for gate level change were not taken into account when running MIKE FLOOD. Fixed MIKE FLOOD FM A false Error would occassionally occur for standard link when located inside one element Fixed MIKE FLOOD URBAN 'Abnormal completion' error at start of simulation for some setups due to un-initialised variable Fixed MIKE 11 Initialisation error (64 bit OS) An error from MIKE 11 would occur on some PC's if MIKE 11 model uses Hotstart as initial condition.
In this case a temporary file is created and attempted to be saved in a system folder which is write protected for users without administrator rights.Fixed MIKE FLOOD URBAN A crash at the start of the coupled simulation due to a problem related to the MOUSE result summary that could not be created for setups where URBAN weirs were linked to MIKE 21 in MIKE FLOOD. Fixed
Service Pack 5, June 2011^ top
No changes have been made for MIKE FLOOD in Service Pack 5.
MIKE FLOOD Service Pack 6, October 2011^ top
Module/Type Error/Inconvenience/New Feature Remarks MIKE FLOOD URBAN Wrong M21 level picked by the MOUSE engine at urban links when link groundlevel is not set to M21 in dhiapp.ini file MIKE FLOOD URBAN Occasionally, MIKE Zero could crash when a MIKE URBAN mdb-file was loaded into MIKE FLOOD the first time Fixed General Manual editing of the couple file, e.g. changing the time step multiplier under M21_Run_Info was overwritten when simulation started. Fixed MIKE FLOOD URBAN Error in linkage definition when linking Urban Weir or Pump to MIKE 21. Erroneous link-type definitions defined from coupling tool. Fixed General When setting the time step multiplier to a number different than 1 (in the couple file under M21_Run_info; 3rd number) in order to run M11 and M21 with different time step the simulation did not run with the correct time steps and the MIKE 11 results are not saved (only the first and last time step). Fixed Lateral Link In some cases, the option of automatic division of Lateral Links could generate gaps between the link segments if cross sections were not located at the where segments were generated. Fixed
MIKE FLOOD Service Pack 7, January 2012^ top
Module/Type Error/Inconvenience/New Feature Remarks Linkage information Corrections has been made to the 'MFLateralLinkConnections.txt' ascii file identifying connections of M11-chainages to M21 cells. M21 outlet Link Users were not previously notified in case Urban outlet links had invert levels lower than the M21 ground level. Warning message has been implemented in the MOUSE-Mike21.log file. Warning issued when difference exceeds a user-defined groundlevel difference (defined in the dhiapp.ini file) Fixed Hotfix caused simulation errors A previously released MIKE URBAN hotfix unfortunately caused MIKE FLOOD simulations to fail (error: 'can not create MIKE 11 Link'). Fixed MIKE FLOOD Urban Coupled MIKE21-MUrban simulations could not run with MIKE URBAN hotstart. Fixed MIKE FLOOD Urban Problem executing simulation on 64 bit operating system. Fixed Resolved in a previous released Hotfix. Solution included in SP7 MIKE FLOOD FM Lateral Links. An error in the formulation for Exponential smoothening for Lateral Links in MIKE FLOOD FM simulations has been identified and corrected. Fixed Resolved in a previous released Hotfix. Solution included in SP7.
Differences in simulation results may occur due to this correction for FM simulations using Exp. Smoothening values different from 1.0.
