Release Note 2016

MIKE HYDRO

Introduction

Welcome to MIKE HYDRO Release 2016. In this Release Note, you will find information about new features of MIKE HYDRO, and what you need to know in order to install and get started with Release 2016.

MIKE HYDRO is our latest generation Graphical User Interface framework for some of the MIKE Water resources software products. Featuring a map based and easy-to-use Graphical User Interface, MIKE HYDRO is a MIKE Zero component which - over the coming releases - will integrate most Water resources products into one, common GUI framework.

Release 2016 of MIKE HYDRO includes:

To install MIKE HYDRO, please choose MIKE Zero in the ‘MIKE Setup’ dialogue box that appears when inserting the MIKE software 2016 USB and clicking the Setup.exe or executing the Setup.exe file from the downloaded installation files. Press the ‘Install’ button to begin installation.

The setup programme will automatically install all necessary files and folders on your computer.

Licence file and dongle

^ top

To use MIKE HYDRO in licensed mode please follow these steps:

  1. You can retrieve the MIKE software licence file (DhiLicense.dat) via the Internet. This requires a working Internet connection and a valid e-mail address. The licence file can be retrieved in two ways:
    • During installation of the MIKE software
    • After installation of the MIKE software, by launching the DHI License Updater through the Windows Start menu
  2. To retrieve your licence file during installation of MIKE software, select ‘Local’ when prompted to ‘Select license type’. In the following dialogue box, select ‘Internet’. At the end of the installation process, you will be prompted to insert your DHI dongle. Insert the dongle and follow the on-screen instructions.
  3. To update your licence file using the License Updater, simply launch the DHI License Updater and follow the on-screen instructions. On Windows 8, search for DHI License Updater.
  4. Alternatively, the licence file can simply be copied to the \Program files\DHI\2016\License or Program files(x86)\DHI\2016\License directory.
  5. After completed installation, you should ensure that your hardware key is attached to the system.

Product invocation

^ top

Launch 'MIKE Zero' from the Windows Start menu. Then you can select MIKE HYDRO from within the MIKE Zero Shell.

Starting MIKE HYDRO without a DHI configured hardware key and valid licence files will cause the programme to run in demo mode. If this happens, a message box will inform you during programme initialisation. When running in demo mode, MIKE HYDRO supplies full access to all editors, computational engines and editing facilities. However, restrictions apply to the setups that can actually be executed as a model simulation.

New features

^ top

Every new release of MIKE HYDRO consists of new modules, new features or corrections to problems or significant inconsistencies discovered in previous releases. Below, please find short descriptions of the most significant news in Release 2016 for MIKE HYDRO specifically and for MIKE HYDRO related options in the general MIKE Zero framework..
The MIKE HYDRO news section below consists of general news for the entire MIKE HYDRO Framework as well as specific module-specific news for the Basin module and the River module respective.

MIKE Zero

Module/type

New feature

Start Page

The MIKE Zero start page has been extended with an extra window that provides you with a faster access to resources and information

Time Series Comparator

New tool that can compare two time series files, compute some performance measures and produce relevant comparison plots

MIKE HYDRO
MIKE HYDRO
- a MIKE Zero product

MIKE HYDRO includes two full featured modules in release 2016:

  • MIKE HYDRO Basin: a module for water resources planning and management in river basins
  • MIKE HYDRO River: a one-dimensional modelling package for comprehensive river network modelling.
Common MIKE HYDRO features

A number of general features have been implemented or further improved for Release 2016:

  • River and Catchment delineation:
    Option for including Digital Elevation Model (DEM) and utilising this for River and Catchment delineation has embedded directly in the MIKE HYDRO GUI - instead of being a separate tool as in release 2014.
  • Catchment digitization is possible through drawing of a catchment polygons
  • River links from catchments to rivers can be defined graphically in the map view
  • GUI performance improvements which especially is notable in larger model setups
  • Highly improved Symbology feature
  • Comprehensive Shapefile Import and Export feature covering almost all MIKE HYDRO features defined with a geographical location
  • Rainfall-Runoff modelling: Hotstart feature included for the NAM rainfall-runoff model
MIKE HYDRO Basin

New or improved Basin module features:

  • Global ranking : Improved solution for allocation of water users:
    Release 2016 includes an extension to the global ranking allocation algorithm. This extension allows to enforce the optimal value for the bifurcation parameter in all relevant bifurcation nodes in a Mike Hydro Model, optimizing the distribution of bifurcation flows and water assignments among all prioritized water users. It is not necessary to activate this extension, since it acts as an embedded improvement of the current algorithm, and therefore it is expected to give higher values of water demand satisfaction than the algorithm available in previous releases.
    Another improvement indirectly added due to this extension is that, because of the bifurcated flows in all bifurcation nodes are no longer a constraint in the network, the bifurcated water is no longer considered as assigned water. And therefore, it can be taken by a water user located upstream to the bifurcation, in opposition with the previous release versions, where the bifurcated water of a node cannot be assigned to a water user upstream or downstream to the bifurcation node, even if this water has not been already assigned, and the water user has the highest GP of the network.
MIKE HYDRO River

New or improved River module features :

  • New add-on module compared to MIKE HYDRO River release 2014:
    • Advection-Disperson module (including boundaries and initial conditions)
    • Water Quality module using ECO Lab
    • Data assimilation including the 'Gain' updating method typically applied in real-time forecasting applications
  • Boundary definitions GUI feature embedded in the river module User Interface
  • Cross sections GUI feature embedded in the River module interface
  • New key features included compared to release 2014 - enabling majority of river applications to be conducted with MIKE HYDRO River:
    • Link channels
    • Hydraulic routing options (Muskingum etc)
    • Dambreak structures,
    • Direct discharge structures,
    • Pumps.
    • Controllable/operational structures including sensor options and control definitions defined through a new equations editor
    • Alignment lines
    • New storage element feature allowing direct definition of storage relations (level-storage) and connection to river branch ends (e.g. for easy definition of single flood compartment)
    • Groundwater leakage
    • MIKE SHE couplings definitions
    • 2D Maps output
    • Timeseries output
  • Import and Export features for high degree of MIKE HYDRO River and MIKE 11 compatibility:
    • MIKE 11 to MIKE HYDRO importer for a seamless import of existing MIKE 11 model setups
    • MIKE HYDRO to MIKE 11 Exporter for export of  MIKE HYDRO Models to MIKE 11
MIKE HYDRO River: Missing features compared to
MIKE 11

Release 2016 introduce MIKE HYDRO River as a ready-to-use River modelling package, which over time will be  replacing our current package; MIKE 11

MIKE HYDRO River will provide similar add-on modules and model features as available in MIKE 11 today including large number of additional GUI features and work-flow improvements.

Release 2016 of MIKE HYDRO River include almost all major modules and features when compared to MIKE 11. However, two key features are missing in the 2016 release. These are:
- All sediment transport modules
- Bridge structures module

Important Notice: MIKE 2016 does include both MIKE 11 and MIKE HYDRO River. Hence, with release 2016 it is possible to conduct most river model applications with MIKE HYDRO River, but in case the above mentioned features are required, it is possible to use the classic MIKE 11 in Release 2016 for these applications.

Release 2016 Service Pack 3

Module/type

Error/Inconvenience/New feature

Status

Common MIKE HYDRO features
Catchment areas were sometimes wrongly estimated, when the Map view coordinate system and the feature coordinate system didn’t match.
Fixed
Common MIKE HYDRO features
Zone numbers are now provided in the result variables from a NAM simulation using elevation zones.
Added
Common MIKE HYDRO features
MIKE HYDRO failed loading a Digital Elevation Model in dfs2 format, with specific coordinate systems.
Fixed
MIKE HYDRO Basin
Editor does not respond after editing of Altitude variable in Irrigation scheme tabular view
Fixed
MIKE HYDRO Basin
Irrigation model produce wrong validation error about combination of features (crops, soil and runoff features) for water user and Soil and Runoff definitions.
Fixed
MIKE HYDRO River
Unexpected errors were sometimes provided when working with Maps results. The unexpected errors have been corrected, while other improved error messages are now added when relevant.
Fixed
MIKE HYDRO River
Wrong validation messages were provided during validation of input data, for missing time series in boundary conditions, culverts using the option "only positive flow" or "only negative flow", and control rules using PID option. Validations have been improved and irrelevant messages are not provided anymore.
Fixed
River simulation engine
The Discharge sensor, which can be used for Controls, did not work properly when specified on a structure.
Fixed
River simulation engine
The additional output item "Discharge on h-points" contained wrong values.
Fixed
River simulation engine
When working with control structures, the control strategy ID saved in the result file was wrong for the 'Unchanged' control rule.
Fixed
Tools
The tool ‘Trim or Extend cross sections’ sometimes cannot process some cross sections, when they’re not valid. When this is the case, the tool now provides detailed errors for the cross sections which are not processed, thus helping towards corrective actions. Furthermore unexpected errors were sometimes provided when applying the tool, and have been fixed.
Added
Tools
The tool ‘Auto generate cross sections’ sometimes created cross sections from survey points on the wrong branch, when multiple branches are close to each other’s. The tool has been improved to create the cross sections only on the intersected branch, if any, and otherwise create them on the closest branch within a given search distance.
Fixed
MIKE HYDRO River, Data Assimilation module
The behavior of the ‘Include error forecast’ checkmark in DA simulations has been changed. Activating the checkmark now enables full updating in both hindcast and forecast period, while de-activating the checkmark now de-activates the updating station completely.
Added
MIKE HYDRO River, Data Assimilation module
When performing simulations with Data Assimilation, the simulation stopped if observed data were not available for the whole hindcast period. In such situations, the simulation will now continue and will start the error prediction when observed data are not available.
Fixed
MIKE HYDRO River, Data Assimilation module
When performing simulations with Data Assimilation, when an error prediction’s equation used a constant Parameter, the Parameter value was not properly transferred to the engine, leading to a wrong error prediction.
Fixed

Error/Inconvenience/New feature

Status

User Interface
US Units and other non-SI units data operations.
A major update of the MIKE HYDRO User interface on data-handling and -processing have been made for SP2, targeting the use of input data utilising units different from SI units.
The update include loading and processing of shape-files, Coordinate systems and projections, DEM's, Synchronization and parameter editing in multiple editor sub-pages, Catchment connections, Cross section processing tools and more.
All to ensure that MIKE HYDRO is now able to work entirely in e.g. a US Unit context.
Fixed
Tools
Load calculator:
When Time steps and period of catchment definitions of MIKE HYDRO Basin model and total runoff files in load calculator are different, the load calculator will crash.   The load calculator must detect this and issue an errror/warning to the user.
Fixed
Import data from Shapefile
In some computers - probably depending on Windows version and configuration, the option for Importing data from Shapefiles would only present approximately 2/3 of the full import dialog. 
Fixed
Tools
Trim or Extend cross sections:
Wrong cross section coordinates length values (s-value) when extending cross sections using the Trim or extend cross sections tool. Additionally, '-INF' values were introduced in the coordinates table which would ultimately cause the MIKE 1D simulation engine to crash during simulation.
Fixed
River simulation engine
Error in simulation for MIKE HYDRO River and for MIKE SHE coupled to MIKE HYDRO river when routing elements are included in branches defined without any cross sections.
Fixed
User Interface
Boundary conditions; Q/h relation type of boundary.
Two problems have been identified:
   1. Calculation of Q/h-relation did not take in to account an eventual Datum value defined in the cross section at the boundary point location
   2. Error in calculated values of the Q/h-relations when using the Manning's method for calculation.
Fixed
User Interface
Cross sections:
Processed data did not take an eventual 'Datum' value in to account when calculating the elevations in the processed data table.
Fixed
User Interface
Catchment connections:
In some occasions, connections were not presented and correctly connected when connecting through the toolbar editing options in Map view.
Fixed
MIKE HYDRO Basin
Seepage contribution in catchments from supply connections was accidently not included in MIKE HYDRO Basin simulations when connections are defined inside a catchment.
Fixed
River simulation engine
Error in coupled HD-RR simulation when applying the 'Linked Fraction' type of connection in River links. The fraction value was not correctly transferred to the engine and wrong simulation results occured.
Fixed
River simulation engine
HD Additional output, structure results from simulation.
Structure result items in additional outputs (velocity, discharge and area) should be saved for all structures in the model including combined/composite structures. An error caused results only to be saved for a single structure instead of all of the defined structures 
Fixed
User Intertace
DEM operations
River delineation based on DEM did not work properly in relation to branch definition and branch connections, if; a) a shape file had been loaded after the DEM was loaded, or b) if some branches was defined  prior to loading and processing the DEM
Fixed
