Randomized trial assesses rainwater harvesting site selection in Iraq, suggesting improved water resource management.

This study aims to identify suitable locations for rainwater harvesting in Shatt Al-Hillah, Iraq, using advanced satellite and geomatics techniques.
Utilized Landsat 9 OLI/TIRS data and a 30-meter DEM to derive key environmental indicators.
Employed GIS weighted overlay analysis, assigning weights to factors such as MNDWI, slope, SAVI, BSI, and aspect.
Generated a final RWH suitability map categorizing areas into highly, moderately, marginally, and unsuitable.
The final suitability map indicated 26.8% of the area as highly suitable for RWH.
The analysis determined that most highly suitable zones were in low-relief areas with high bare soil visibility.
Validation with Google Earth Pro and site visits confirmed the reliability of the results.
