Released under the GNU General Public License v3.0 or later (GPL-3.0-or-later).\r\n\r\nAR-Tarseem is a complete DEM-to-hydrograph watershed modelling tool. From a metric DEM and a pour-points layer, it produces:\r\n\r\n- Streams, Catchments, Longest Flow Paths (three Tc estimates), optional sub-basins / sub-LFPs / reaches / junctions.\r\n\r\n- Special Delineation Points: enforce junctions at dam locations (snapped to the main flow path), split sub-catchments at the points only or combined with the area-based subdivision, and define any point as a Reservoir with modified-Puls storage routing (elevation-volume curve + spillway/orifice structures, or a storage-discharge table) - with inflow, outflow, attenuation, storage, and stage outputs.\r\n\r\n- Design-storm hydrographs per catchment / sub-basin / junction / reach: CSVs + interactive HTML charts, with an editable output window so every hydrograph is complete (recession to zero).\r\n\r\n- Curve Number from a raster (auto-aligned to the DEM) or a single constant value; adjustable lambda = Ia/S (0.01-0.5).\r\n\r\n- Rainfall: all four SCS/NRCS 24-h distributions or a custom hyetograph CSV; custom return periods; Thiessen station weighting; TRRL-UK / Riyadh / fixed Areal Reduction Factors.\r\n\r\n- Reach routing: Lag, Muskingum, and variable-parameter Muskingum-Cunge on a trapezoidal channel.\r\n\r\n- HEC-HMS interchange: .basin (with true Reservoir elements), per-return-period .met files, and a .pdata carrying the reservoir Elevation-Storage tables (HEC-HMS 4.7-4.13 / WMS).\r\n\r\n- Automatic QML styling. Uses ONLY libraries that ship with QGIS: numpy, osgeo (GDAL), QGIS API.\r\n\r\nThe plugin can also write its network as an AR-Awdiya project file (.json) for further interactive network editing and reporting.", "homepage": "https://github.com/amrrefaiy-hash/AR-Tarseem", "repository": "https://github.com/amrrefaiy-hash/AR-Tarseem", "tracker": "https://github.com/amrrefaiy-hash/AR-Tarseem/issues", "author": "Ahmed M.
