Example	Description	Level
Simple script	Wave runup on a linearly sloping bed using a rectangular mesh. Introduces the core ANUGA workflow: mesh creation, set_quantity, boundary conditions, and the evolve loop. No external data files required.	Beginner
Simple notebook	The same runup scenario presented as an interactive Jupyter notebook with inline animation via Domain_plotter. A good starting point for exploring ANUGA interactively.	Beginner
Domain from regions	Builds an unstructured mesh from a bounding polygon with multiple tagged boundary segments using create_domain_from_regions. Demonstrates mesh refinement with maximum_triangle_area and multi-tag boundary assignment.	Intermediate
Domain with riverwalls	Adds infinitely-thin levee/riverwall structures to a mesh using breaklines (to align triangle edges with the wall) and create_riverwalls. Compares flow with and without the wall in place.	Intermediate
Flooding example	Real-world urban flood model of Merewether, Newcastle (NSW) driven by DEM topography, an Inlet_operator hydrograph, and building exclusion polygons. Results are compared against benchmark observational data using SWW_plotter.	Advanced
Tsunami benchmark	Okushiri Island tsunami runup (IWTS Benchmark 2) with incoming wave specified via Transmissive_n_momentum_zero_t_momentum_set_stage_boundary and spatially interpolated bathymetry. Simulated water-surface time series are compared against physical model gauge data.	Advanced
