A Hydraulic-Topology Transformation Framework for Free-Surface and Pressurized Flood Modelling in Multilayer Underground Spaces

Supporting data for a multilayer underground-space flood-modelling framework A Hydraulic-Topology Transformation Framework for Free-Surface and Pressurized Flood Modelling in Multilayer Underground Spaces The framework converts independently generated layer-wise meshes into a singlemultilayer hydraulic topology: it stores the vertical geometry of each cell,reconstructs the non-manifold junctions where layers meet, and assigns theboundary conditions the TPA-2D solver needs to carry a flow across floors andthrough the transition between free-surface and pressurized states. This recordholds the figures of the manuscript in vector form and the computed results thefigures are drawn from.
