🌊 What is Marine & Coastal Engineering?

Marine & Coastal Engineering is a multidisciplinary branch of engineering that deals with:

Protecting coastlines from erosion, flooding, and sea level rise
Harnessing marine resources such as tidal, wave, and wind energy
Designing structures to withstand harsh marine conditions, including:
- Ports & harbors
- Breakwaters
- Offshore platforms
- Subsea pipelines and cables
Understanding natural processes like waves, tides, and sediment transport

It combines civil engineering, oceanography, fluid mechanics, environmental science, geology, and marine biology.

🧱 Main Focus Areas

Coastal Engineering: Erosion control, flood defense, shoreline management, numerical modeling
Marine Engineering: Offshore structures, subsea systems, port design, hydrodynamics

⚙️ Core Technical Concepts

Wave Mechanics: Understanding how waves interact with coasts and structures
Tides and Currents: Prediction, analysis, and design relevance
Sediment Transport: Coastal stability and dredging planning
Hydrodynamic Modeling: Tools like CROCO, SWAN, MIKE21

⚡ Applications
