Lekan - Lekan version 2.2.0

Following features were added since version 2.1.4 :

• Import data from external sources: it is now possible to import data from Delft-FEWS files (rainfall and flow rate) and from remote server Hubeau (real-time flow rate). Infrastructure is ready to add more data providers.

• Add spatial position capability to rainfall station in the rainfall manager

• Improve the user interface for plots: customize legends (position, column count), activate/deactivate curves, change the color associated with time series

• Add the possibility to associate gauged hydrograph to a watershed, hydrograph is entered in a table or imported from external sources

• Overlay gauged hydrograph or result from another meteorological model in the runoff hydrograph calculation plot

• Introducing the Hydraulic Network module: node/link to simulate flow propagation. Following elements can be added to the network

  • Simple junction nodes that sum hydrographs from upstream links and eventually a produced gauged hydrograph
  • Watershed nodes that produce calculated runoff hydrograph or a gauged hydrograph that are summed to hydrographs from upstream links
  • Routing links that can transform an input hydrograph to an output hydrograph with a specified flow routing to simulate the propagation

• Improve the displaying of the description of formulation/method

• Date/Time in locale format

Lekan - Lekan version 2.1.2

The following issues have been fixed:

• output hydrograph had a variable time step, that was not convenient when exporting values to other tools that does not support variable time step. In this new corrective release, the user can choose to have a constant time step.
• when creating a new rainfall, a time offset could appear in the output hydrograph table equal to the difference from UTC and local time.

• removing burning lines tool could crash Lekan (when clicking where there was not burning line)
• rainfall importer didn't recognize end of line for some files (CSV windows)
• header text of rainfall table was cut
