"What is the finest piece of engineering in nature for you? For me, it has to be the mangrove... filtering salt, breathing through aerial roots, protecting coastlines."
The matrix of mangrove roots increases the drag coefficient ($C_d \approx 1.2 - 1.8$), creating a porous media barrier that forces turbulent kinetic energy dissipation, reducing wave heights exponentially across forest width ($H_x = H_0 e^{-kx}$).
