{"name": "WetSpass-M Modern", "package_name": "wetspass_modern", "description": "Spatially distributed monthly water balance model for QGIS. Estimates groundwater recharge, evapotranspiration, surface runoff, and interception using GeoTIFF inputs. Adds a dynamic soil-water bucket to the original Wetspass-M 2016 physics, with automatic spin-up convergence detection, focused recharge along ephemeral streams, a climate-zone-based recharge cap, and polygon-based output cropping.", "about": "WetSpass-M Modern is a modernized version of the original Wetspass-M 2016 model (Abdollahi, Bashir & Batelaan, Vrije Universiteit Brussel). It estimates diffuse and focused groundwater recharge, evapotranspiration, surface runoff, and interception at monthly, seasonal, and annual time steps.\nThe modernization preserves the original physics but adds:\n- A dynamic soil-water bucket replacing the original quasi-steady-state assumption.\n- An ET cap at (P - runoff) instead of P, ensuring the catchment-scale mass balance closes exactly.\n- Groundwater-fed ET reported separately as Cell_gw_discharge.\n- Nodata-preserving aggregation so annual rasters share the same valid-cell mask.\n- Automatic spin-up with convergence detection (mean |dS| compared to max(1 mm, 0.5% of mean annual P)).\n- Automatic checkpointing after every completed month.\n- A Skip to final cycle button on the Progress tab.\n- A dedicated Water Balance tab with a single, pure physical mass balance closure equation and an acceptability verdict.\n- A Focused Recharge module for streambed infiltration along ephemeral stream networks.\n- A user-selectable combine method for diffusive + focused recharge.\n- A Crop outputs to boundary tool.\n- A River Conductance module for MODFLOW 6 integration.\nInputs: 12 monthly climate rasters, a DEM, land use, soil, optional slope, and optional geology.\nOutputs: monthly, seasonal, and annual GeoTIFFs of every flux, plus a per-month summary table.\nOriginal authors (Wetspass-M 2016):\nK.
