BlueM.Wave v1.6.1 released

BlueM.Wave v1.6.1 has been released!


It’s been more than a year since the release of v1.6 and quite a few additions, changes and improvements have been made to BlueM.Wave.


New features and improvements

  • Added support for loading and saving Wave project files (*.wvp) (#705)
  • Added a button for displaying time series properties in a table view (#711)
  • Added the ability to load TALSIM simulation results using the clipboard (by pressing Ctrl+V) (#695)
  • Added an “AnnualStatistics” analysis function which calculates statistics such as min, max, avg and volume of a time series for each hydrological year
  • The “Comparison” analysis function now fits a simple linear regression line to the data (using the Math.NET Numerics library)
  • The analysis function “Histogram” now allows the user to specify the bins (#397). Also, the histogram result data is now written to the log.
  • The analysis function “MonthlyStatistics” now writes the result data to the log
  • Added a button for removing user-specified error values from series
  • Added a button for renaming series
  • Added a dropdown button for zooming to a specific series
  • Added support for exporting series to CSV format (#318)
  • Added support for importing files in the ZRXP format (*.zrx)
  • GoodnessOfFit” (GoF) analysis function:
    • Added “Logarithmic Nash-Sutcliffe Efficiency” as a new GoF parameter
    • The GoF parameters can now optionally be calculated for individual hydrological years
  • Added support for importing BW_TMP.DAT result files from HYDRO_AS-2D


  • Error values in time series such as e.g. -777 and -9999 are now imported and displayed as regular values. Previously, when importing from BIN and DWD-T-L format, these would be replaced with NaN. The new “Remove error values” function can be used to remove these error values, if desired. (#693)
  • Analysis “GoodnessOfFit“: Volume error is based on actual volume integrated over time if the time series unit ends with “/s”
  • Removed support for the DWD-T-L format
  • If a time series contains duplicate nodes, the duplicate nodes are now simply discarded and a warning is written to the log instead of aborting the import


  • The decimal mark selector in the import series dialog now actually works (#351)
  • Comparison” analysis function: changed the result series to a point series because a line series in TeeChart automatically sorts itself by the x-values and thus connects the points in the wrong order (not time-based)

BlueM.Opt v1.6 released

BlueM.Opt v1.6 has been released!


The main change is the complete translation of the interface to English. Also, most of the documentation in the BlueM wiki has been translated to English.  Furthermore, Talsim-NG has been added as a new simulation engine.


  • New
    • Added support for the simulation engine Talsim-NG (© SYDRO Consult GmbH). Talsim-NG engine v3.0.1.6 is included.
  • Changed
    • Translated the main GUI and all messages related to PES (Parametric Evolution Strategy), SensiPlot (Sensitivity Analysis) and Talsim-NG to English.
    • Updated BlueM.Wave to v1.6
  • Fixed
    • When displaying the decision space as a scatterplot matrix and not selecting all optimization parameters for display, any selected solutions were being displayed incorrectly.
  • Removed
    • Dropped support for the objective function “IHA-Analysis”, IHA-Software no longer included.

Current status and further development

BlueM is gaining more momentum. And more interest. The BlueM Development Team has been asked to present the current status of BlueM and it’s further development both at the “DAWAKO 2017” at Technische Universität Darmstadt and the “German Day of Hydrology 2017” at Trier University.

Current status

One of the major advantages of BlueM.Sim is it’s modular structure and the outer time loop, making the implementation of new modules relatively easy and straightforward. Currently implemented modules comprise natural catchment parts (including detailed SWAT modeling and diffuse pollution); lakes, ponds, and reservoirs (including complex management schemes); and river segments (including structured cross sections, flood routing and water quality processes).
Urban structures like urban catchment parts, sewers, combined sewer overflows and waster water treatment plants have been coupled via OpenMI so far.

BlueM.Sim is tightly coupled to BlueM.Wave for time series management and BlueM.Opt for multi-objective optimization tasks. BlueM.Wave is able to import and export a wide range of different time series formats whereas BlueM.Opt is equipped with several interfaces to interact with other simulation software.

Coupling of BlueM.Opt, BlueM.Sim, BlueM.Wave and interfaces.
Coupling of BlueM.Opt, BlueM.Sim, BlueM.Wave and interfaces.

Given it’s wide range of functionalities, users of BlueM.Sim, BlueM.Wave and BlueM.Opt range from research institutions over government institutions to private companies. For example, the hydrological model core of BlueM.Sim forms the base of simulation-based analysis and planning methodology of the German Federal State of Hesse to identify critical impacts on receiving water bodies from the identification of critical impacts due to waste water discharges. For further application examples of BlueM please refer to our application page.

Further Development

Aside from regular bug fixes and enhancements, recent development has been focused on BlueM.Wave, where many new functionalities have been released in version 1.6.

Currently, we are working on the direct integration of urban modules into the BlueM.Sim model core. While discharge routines have already been implemented and are currently being tested and validated, the development focus is now on implementing water quality routines as well, also for more stagnant water bodies like slow flowing river stretches above weirs, lakes and reservoirs.

Further emphasis will be put on the capabilities of BlueM for immission based modeling together  with respective post processing and evaluation procedures.

Stay tuned…

BlueM poster contribution at TdH 2016

Michael Kissel was asked to present the blueprint for a direct integration of urban drainage modules into BlueM at the “Tag der Hydrologie 2016/Day of Hydrology 2016” held in Koblenz, Germany. The overall topic of the conference was “Water resources – connecting knowledge in river basins”. BlueM, with its integrated model approach and the planned development was a perfect contribution to this topic.
