- Hard engineering solutions: seawalls, groynes, revetments, and breakwaters.
- Soft engineering solutions: beach nourishment, dune restoration, and vegetation stabilization.
- Hybrid approaches: integrating hard and soft techniques.
- Case studies on successful erosion control projects.
Day 4: Climate Change Adaptation & Coastal Resilience Strategies
- Impact of climate change on coastal drainage and erosion patterns.
- Adaptive drainage solutions for sea-level rise and extreme weather.
- Nature-based solutions: mangrove restoration and artificial reefs.
- Smart monitoring and early warning systems for coastal flooding.
- Policy and planning frameworks for coastal resilience.
Day 5: Case Study – Coastal Drainage & Erosion Control in a High-Risk Area
- Scenario: Addressing severe flooding and erosion in a coastal city.
- Data Analysis: Reviewing historical storm events, tidal data, and erosion trends.
- Solution Development: Designing a comprehensive drainage and erosion control plan.
- Simulation & Modeling: Running hydrodynamic models to assess design performance.
Discussion: Evaluating cost-effectiveness and long-term sustainability of the proposed solutions.
