Short Summary

This paper presents a fully reproducible geospatial and hydrological processing workflow for basin-scale environmental and climate-risk analysis, demonstrated for the Riyadh Basin, designed for national-scale deployment in Saudi Arabia.

Objective

• To develop a fully reproducible geospatial and hydrological processing workflow and analytical architecture for environmental and climate-risk assessment to support the UNDP/MoMaH National Spatial Strategy (NSS) revision.

Study Configuration

• Spatial Scale: Riyadh Basin (operational example), with methods designed for national-scale deployment across Saudi Arabia. Data resolution is 30 meters.
• Temporal Scale: Not explicitly stated, but implies a static assessment of environmental and climate risk factors.

Methodology and Data

• Models used: D-infinity hydrological pipeline (for DSM-to-DTM filtering, pit filling, breaching, flow accumulation, slope, topographic wetness index, and stream extraction).
• Data sources: AW3D30 (for Digital Surface Model - DSM). Implied data for climate extremes, land cover, ecological assets, and anthropogenic pressure for diagnostic figures.

Main Results

• A complete 30-meter environmental and climate-risk analytical architecture was developed for the Riyadh Basin.
• A D-infinity hydrological pipeline was implemented, processing AW3D30 data for various topographic and hydrological parameters.
• Thirteen geospatial diagnostic figures were generated, covering DEM structure, hydrology, climate extremes, land cover, ecological assets, and anthropogenic pressure.
• A technical note was produced, documenting the methodology, reproducibility principles, and alignment with NSS requirements.

Contributions

• Development of a fully reproducible and version-controlled geospatial and hydrological processing workflow for environmental and climate-risk analysis.
• Creation of a scalable methodology designed for national-scale deployment across Saudi Arabia.
• Provision of a comprehensive technical note detailing methodology, reproducibility, and alignment with national strategic requirements.
• Establishment of a transparent framework for technical assessment and verification of spatial analytics.

Funding

• UNDP/MoMaH National Spatial Strategy (NSS) revision.
