SCS-CN Builder QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Automated SCS Curve Number calculation from LULC and Hydrologic Soil Group data, with optional CORINE Land Cover reclassification, selectable default/custom CN lookup tables, CN2/CN3 maps, basin statistics, quality-control checks and an HTML report.
About
SCS-CN Builder is a QGIS plugin for automated estimation of Curve Number values using the Soil Conservation Service method. It integrates land use/land cover raster data, Hydrologic Soil Group raster data and basin polygons to generate CN2 maps for average antecedent moisture conditions, CN3 maps for high antecedent moisture conditions, basin-level zonal statistics, quality-control summaries and an HTML calculation report. The plugin can use LULC rasters already reclassified to the standard 1-7 scheme or automatically reclassify original CORINE Land Cover codes into the standard 7-class scheme. It can use the embedded default CN lookup table or a user-supplied CN lookup CSV.
