Présentation d’hydra au colloque FOSS4G 2018 en Tanzanie

Hydra présenté aux décideurs, développeurs et utilisateurs de logiciels libres

Le 30 août dernier, à Dar Es Salaam (en Tanzanie) se tenait la rencontre annuelle des décideurs, développeurs et utilisateurs de logiciels libres dédiés à la géomatique, organisée par l’OSGeo : FOSS4G 2018 (Free and Open Source Software for Geospatial).

Notre partenaire Oslandia, spécialiste des logiciels en Open Source, s’est rendu à ce colloque et y a présenté hydra, fruit de notre collaboration.

Abstract :

We present Hydra, an OpenSource platform for hydrology and hydraulics modelling. Hydra is the first OpenSource tool allowing to simulate the full water cycle, directly integrated into a GIS software.

Hydra is based on QGIS and PostGIS, and provides a full platform for water management :

  • hydrology
  • fluvial modelling
  • wastewater
  • water quality
  • solid transportation
  • water network / river coupling

We chose to bring the water simulation part of the software into QGIS/PostGIS, for various obvious reasons :

  • QGIS is a great GIS application development platform
  • Simulation involves GIS data preparation before computation
  • .. and visualization of the results after computation
  • PostGIS is the best place to store data and complex models
  • The dynamism of OpenSource community and the QGIS project directly benefits to Hydra
  • … and Hydra is made available to the OpenSource ecosystem

We want Hydra to become the de-facto OpenSource water management platform, and look forward to enlarge the community around it. The platform is already used for large-scale projects, to assess its efficiency and confirm its adaptation to real-world use cases. After the presentation of the platform itself and its features, we showcase some use cases it has been applied to.

The Hydra platform was born from a collaboration between Hydratec, a hydraulics engineering firm, and Oslandia for its OpenSource GIS knowledge. We also present the organisational part of the creation of this platform, as an example of efficient collaboration and mutualization of resources and competences to create OpenSource software.
