Brief Description
Coastal regions worldwide are increasingly susceptible to the severe impacts of storm surges, particularly in archipelagic nations like the Philippines, which face numerous tropical cyclones annually. This study focuses on the Laoag River Coastal Zone in Ilocos Norte, Philippines, to examine the influence of tide and wind on storm surge levels during Typhoon Ineng in 2015 using the DELFT3D modeling software. The research aims to enhance the understanding and predictive capability of storm surges in this specific area, contributing to improved disaster preparedness and coastal management practices.
Expected Output
- Detailed Storm Surge Simulations:
- High-resolution simulations of storm surge levels influenced by various tidal and wind conditions during Typhoon Ineng.
- Visual representations (maps and graphs) of surge heights and flood extents for different scenarios.
- Calibrated and Validated DELFT3D Model:
- A calibrated and validated DELFT3D model specific to the Laoag River Coastal Zone, with improved accuracy in predicting storm surge levels.
- Documentation of the calibration and validation processes, including performance metrics such as RMSE and NSE.
- Analysis of Tidal and Wind Influences:
- In-depth analysis of the impact of tidal variations on storm surge heights, demonstrating the significant differences between high tide, low tide, and mean tide conditions.
- Evaluation of the combined effects of tide and wind on storm surge levels, identifying critical scenarios that result in peak surge heights.
- Implications for Coastal Management:
- Recommendations for improving early warning systems by incorporating real-time tidal and wind data.
- Strategies for adaptive coastal zone management, including updated zoning regulations, infrastructure improvements, and community-based disaster preparedness plans.
By delivering these outputs, the study aims to enhance predictive capabilities, support effective coastal management, and ultimately reduce the risks and impacts of storm surges in vulnerable coastal regions.
