Overview

This analysis documents significant sedimentation and abrasion in coastal areas, highlighting spatial patterns and implications for management.

Key Points

  • Sedimentation in the coastal area reached 251.78 hectares, while abrasion was only 30.12 hectares during the observation period.
  • Average annual sedimentation rate over 11 years was approximately 22.89 hectares, compared to the abrasion rate of 2.74 hectares.
  • Remote sensing and geographic information systems were utilized to analyze shoreline changes using Landsat 8 imagery.
  • Findings indicate a greater dominance of sedimentation, emphasizing the need for sustainable coastal management.
