Overview

Geospatial modeling uncovers high soil erosion vulnerability and active tectonic signatures across coastal sub-basins, highlighting critical priority zones for sustainable infrastructure planning.

Key Points

  • Assess soil erosion vulnerability and relative tectonic activity across 24 sub-basins along the southern Red Sea coast to support climate-resilient development.
  • Analyzed 24 sub-basins using 12.5 m ALOS PALSAR digital elevation models to evaluate 22 morphometric parameters via a weighted compound ranking system.
  • Integrated geomorphic indices, including hypsometric integral, valley-floor width-to-height ratio, and basin shape, into Relative Tectonic Activity (RTA) and Revised Universal Soil Loss Equation (RUSLE) models.
  • Identified sub-basins 8, 7, 22, 18, 23, 13, 3, and 9 as the highest-priority areas for soil conservation interventions.
  • Observed hypsometric integral values ranging between 0.04 and 0.48, pointing to mature landscapes subject to geomorphic and tectonic reactivation.
  • Demonstrated strong spatial correlation among morphometric compound ranking, RTA interpretations, and RUSLE soil erosion assessments.
