Index of notebooks describing new GeoClaw features

• NewFeatures.html - Overview of some new features, with a motivating example.
• pcolorcells.html - Version of pcolormesh that works better for finite volume grid cells, and application to geoclaw.Topography.plot.
• RuledRectangles.html - Explanation of Ruled Rectangles, polygons for which it is easy to check inclusion of a point
• FlagRegions.html - A new way of specifying regions to guide AMR, e.g. as a Ruled Rectangle rather than a simple rectangle.
• SetEtaInit.html - Specify a spatially-varying initial water elevation $\eta = h + B$ rather than using the single value sea_level everywhere. Sometimes necessary in regions where land is deformed by an earthquake and/or to initialize lakes at different elevations.
• MarchingFront.html - Tools to select points from a topography DEM that satisfy given constraints on elevation. Used to determine dry land behind dikes and to determine fgmax points or refinement regions close to the shore.
• FGmaxGrids.html - FGmax Grids - specifying points and plotting results
• ForceDry.html - Force certain areas to be dry initially even if the topography DEM value is below 0.
• gridtools.html - Tools to extract 2d uniform grid or 1d transect from 2d AMR solution.

More examples

• MakeFlagregionsCoast.html - Make a ruled rectangle flagregion along the coast, using the marching front algorithm.

The directories below have additional examples of using these tools and then setting up and running the Clawpack/GeoClaw Fortran code:

• The directory examples/amrclaw_flagregions has an AmrClaw illustration using flagregions.
• The directory examples/geoclaw_test1 has a GeoClaw illustration with synthetic topography; see geoclaw_test1_index.html in that directory.
• The directory examples/geoclaw_whidbey1 has a GeoClaw illustration with real topography.
