| Abstract | Coastal degradation poses a growing threat in India, affecting infrastructure and the livelihoods of coastal communities. Along the 48 km Visakhapatnam coast (Bheemili to Yarada), seasonal beach changes are driven by waves, tides, currents, and human interventions like dredging and jetty construction. Bimonthly beach profilings are conducted at ten sites for three years i.e. during 2023,2024 and 2025 Pre-Monsoon, Monsoon, and Post-Monsoon seasons, combined with littoral data, revealed significant morphological shifts. The southern coast (Yarada to Submarine) saw major erosion in the year 2023, especially during the months of July¿August and sediment deposition occurred in the year 2024. The northern stretch (Rushikonda to INS Kalinga) gained sediment in the year 2023 but eroded in the year 2024. Bheemili consistently showed erosion, likely due to its embayed nature. These findings identify key erosion and deposition zones, aiding future coastal planning and management. |
