DESCRIPTION:Hydrodynamic and morphodynamic modeling in the littoral zone re
 mains a key goal of coastal researchers and engineers: recurring needs inc
 lude understanding past extreme wave\, current\, and storm surge events\; 
 simulating how new construction will impact the coast\; and investigating 
 how the shoreline will respond under Sea Level Rise (SLR) scenarios. The f
 ree and open source XBeach model from Deltares (https://www.deltares.nl/en
 /software-and-data/products/xbeach) represents an obvious gateway to the w
 orld of coastal hazard numerical modeling\, validated through a growing ar
 chive of peer-reviewed studies. Still\, initial model creation and setup c
 an pose a barrier to entry with a fairly steep learning curve. While many 
 excellent software solutions exist to aid model generation\, limitations c
 an include Operating System (OS) specificity\, proprietary licenses\, or r
 equired programming skills. Enter QBeach: this initiative aims to collect 
 existing Python tools into a familiar QGIS (https://qgis.org/) plugin desi
 gned to set up XBeach models\, impose boundary conditions\, generate basic
  files needed for models to run\, and quickly visualize model outputs. The
  OS agnostic QGIS serves as a near perfect ecosystem to host such a tool w
 ith its wide adoption in the scientific community\, Graphical User Interfa
 ce (GUI) accessible through PyQt\, and integrated Python scripting. Furthe
 r\, XBeach users likely already rely upon QGIS to assemble model inputs su
 ch as bathymetry and topography raster data from various sources. As of Ap
 ril 2026\, a rough QBeach prototype lives on Github (https://github.com/JT
 Melly/QBeach) that\, ideally\, will be added to the QGIS plugins repositor
 y pending further testing\, debugging\, and usage documentation. The prese
 nt version (0.1) interpolates bathymetry data to an XBeach model grid\; ge
 nerates input parameter\, tide\, and wave boundary condition files\; and p
 rovides basic visualization of NetCDF output files resulting from XBeach m
 odel runs. The roadmap for additional features includes treatment of irreg
 ular grids\, bed roughness coefficients\, sediment grain sizes\, non-erodi
 ble surfaces\, and further model output diagnostics. This presentation add
 resses themes of collaboration on tools to address persistent research que
 stions\, Artificial Intelligence (AI) augmenting human programming skills\
 , and free and open source software development.
