QGIS-Tim

QGIS-Tim is an open source project for multi-layer groundwater flow simulations. QGIS-Tim provides a link between QGIS and the open source analytic element method software: TimML (steady-state) and TTim (transient).

The benefit of the analytic element method (AEM) is that no grid or time-stepping is required. Geohydrological features are represented by points, lines, and polygons. QGIS-Tim stores these features in a GeoPackage.

QGIS-Tim consists of a “front-end” and a “back-end”. The front-end is a QGIS plugin that provides a limited graphical interface to setup model input, visualize, and analyze model input. The back-end is a Python package. It reads the contents of the GeoPackage and transforms it into a TimML or TTim model, computes a result, and writes it to a file that the QGIS plugin loads.
