QGISRed is a free plugin of the open software QGIS, developed by the IIAMA of the UPV, which takes advantage of many features provided by this platform to make easier building hydraulic models from the corporate information of water utilities, and keep it updated. QGISRed allows to build even simple models on a blank canvas, as in EPANET, replicating all the capabilities of this application and extending them, or fully realistic water distribution networks models, taking into account other components that EPANET does not currently support, such as service connections, shut-off valves, measurement sensors, DMAs, non-revenue water while differentiating latent and specific leaks, etc. New elements can be connected with customer points or automated meter readings, SCADA measurements, maintenance operations, leaks, etc. Moreover, all QGIS capabilities for editing, visualizing or geoprocessing data can be used seamless with the additional tools developed in QGISRed, allowing to increase its potential.

The first part of this interactive course will show the additional capabilities that QGISRed offers on top of EPANET for building traditional hydraulic models, such as new graphic editing tools, layout debugger tools, DTM elevations interpolation, pipes roughness assignment by age and material, units and roughness conversion according to the loss formula applied, nodes demands application based on urban mapping info, etc. Model data can be also imported from shapefiles or INP files and exported back to EPANET or analyse the results directly from QGISRed.

In the second part of the course, the QGISRed extension to build Digital Twins will be shown, which allows to add new elements to the model and connect them with the registered consumptions in various formats, with  data field measurements, or with maintenance operations, thus allowing a faithful reproduction of network real behaviour . When using temporal real data, QGISRed allows to show the behaviour of the network at any chosen time. The connection with real data makes it also possible to assess for KPIs over a time period, to carry out water balances by sectors at any time, or to simulate operations starting with network conditions at any given time, and also to keep the model continuously calibrated.
