[Qgis-developer] Hydrological toolbox

We have been working on a hydrological toolbox ENKI since 2002, for the Norwegian hydropower producer Statkraft.

Statkraft has recently decided to release ENKI under LGPL. At this time, however, there is no established OS project (WEB site, mailing list, core committer group etc). I'd be happy to see ENKI developing an interface with QGIS and other Open Source GIS tools.

ENKI is a spatio-temporal model building framework, in which a model is built up from subroutines compiled as dll plugins. Although developed for distributed hydrological models, ENKI poses no restrictions on what the routines do, as long as they're happy with being called once for each time step. The interface between subroutines are GIS variables; either rasters or point networks. ENKI validates the model setup and provides all the administration to initialise, calibrate and run the model.

Having used MFC during the development, ENKI is so far tied to commercial Visual Studio versions. I am hoping for resources to get rid of that dependency. The GUI and core are separated, so it should be possible to call the EnkiAPI.dll from other software.

ENKI was presented at EGU2012 in Vienna, and only the lack of an open data set to go with it as tutorial, is delaying its distribution. We are working on that, hoping to get ready within the coming week. I haven't really looked into the different possibilites for how to deploy or manage an Open Source project, suggestions are welcome.

Best regards,

Sjur K :-)

Hi Robert

Werner wrote the original Wiki page, I just got the idea of a Hydrological toolbox from the other post. However there seem to be a few people interested in the idea, so hopefully we can pool our resources to achieve this.
