Version: [6495] WetSpass-M Modern 2.4.1

2.4.1 — Universal Cropping & Pure Closure
- All raster calculations (Rain, DEM, Soil, etc.) are now strictly
forced to use the cropped boundary (outputs/cropped_inputs) if
available.
- Removed the 'Modified Formula (With SW_Inflow)' from the Water
Balance tabs to avoid mathematical ghost water.
- Enforced a strict fail-safe: irrigation only runs if explicitly
checked by the user.

2.4.1 (2026-10-25)
- Added instant 'Skip to Final Cycle' that aborts the current
month/block.
- Enabled 'Run' button during paused states to allow starting fresh
runs.
- Default spin-up cycles increased to 30 (safe due to early
convergence exit).
- Added Geology Map input and Grid consistency checks.
- Strict mass balance: removed all automated SW/GW inflow
approximations to enforce a single, pure physical closure equation (P
- AET - SR - R - dS = 0).

2.4.0 (2026-10-25)
- Added "River Conductance" tab for MODFLOW 6 RIV package integration.
- Implemented Field-Anchored Geomorphic Scaling for conductance,
depth, width, and stage.
- Added Stream Typology weighting (Perennial, Intermittent,
Ephemeral).
- Added automatic Gaining/Losing stream classification based on
streambed vs water table elevation.
- Added export of MODFLOW-ready CSV tables with absolute Stage and
Rbot elevations.
- Implemented Multi-Flow Direction (MFD) hydrology engine for accurate
stream routing in flat areas.
- Added Smart Cache clearing for GWD capping.
- Beautified UI (Green Run button, formula reference box, green
progress bars).

2.1.2 — Hybrid ET, bucket floor, reconciled closure
2026-10-14
- Hybrid ET bank. The root-zone water term used in the ET formula now
interpolates between the modern small-bank factor (x10) and the
original Wetspass-M 2016 large-bank factor (x1000) based on how full
the soil bucket is.
- Minimum bucket capacity floor of 50 mm. Prevents thin-soil cells
from overflowing on every rain event and producing spurious recharge.
- Water Balance tab now reconciles focused recharge correctly.
