Did you know? | No GIS software needed

Flood Modeller offers a range of GIS tools and capabilities enabling users to create, read, and edit geospatial vector and raster data file formats directly within the software’s intuitive interface. These tools can be used to build components of a 2D model or post-process the results of its simulation. No need for expensive third-party software!

Components of a 2D model, including the active area, boundary condition or topographic features can be quickly built directly within Flood Modeller’s GIS interface. You can also embed 1D hydraulic structures within a 2D model or create links with 1D river and 1D urban drainage models.

Here’s an outline of some of the key GIS functionality within Flood Modeller:

Computational area – Easily specify the location and size of the computational grid of a 2D domain.

Active area – Quickly define an active area of a 2D domain (where the shallow-water equations are solved) to reduce the number of 2D cells being modelled, accelerating model run times.

Boundary line -.Simply specify where water can enter or exit your 2D model by creating a boundary polyline shapefile that defines the location of a boundary input within your 2D model.

Embedded structures - Seamlessly define 1D structures such as culverts, weirs, or orifices.

Link line generator – Automatically generate the shapefile required for linking 1D and 2D models.

Topographic features – Points, Polyline and Polygon help with the definitions/local adjustments of the model’s ground-elevation data. It is useful in certain cases such as the addition of a building that blocks a flow path or where a bridge deck is masking an existing flow path.
