Eastern Nile SWAT+ & WEAP Modeling

I am developing an integrated water-resource model for the Eastern Nile, with the focus narrowed to the Blue Nile Basin. The core task is to build, calibrate and validate a detailed SWAT+ representation of the basin’s hydrology and then couple the results to a WEAP framework so I can test alternative water-allocation scenarios across sectors and seasons.

Key objectives
• Generate a reliable basin-scale hydrologic simulation that captures streamflow, reservoir dynamics and return flows under present land-use and climate conditions.
• Import SWAT+ outputs into WEAP to simulate allocation rules, policy changes and projected demands, providing decision-relevant indicators such as unmet demand, environmental flow compliance and system reliability.

Required workflow
– Compile and preprocess all spatial data (DEM, land use, soils) and observed hydro-meteorological records.
– Set up the SWAT+ model (QSWAT+ in QGIS or ArcSWAT 2012 in ArcGIS—whichever you prefer) and run sensitivity analysis, calibration and validation.
– Configure a WEAP schematic of the Blue Nile, link it to the calibrated SWAT+ outputs and build baseline plus at least three allocation scenarios.
– Document every modelling step clearly so future updates are straightforward.

Deliverables
1. Calibrated SWAT+ project folder with input data, parameter files and validation statistics (NSE ≥ 0.6 at key gauges).
2. WEAP project file fully linked to the SWAT+ results, including baseline and scenario results through year 2050.
3. Technical memo (≈15 pages) summarising methods, assumptions, calibration metrics and scenario findings.

I already I don't have datasets or previous shapefiles. The work should be reproducible on a standard Windows 10 machine. Please outline the software versions you intend to use and the approximate timeline for each major step so we can agree on milestones before starting.
