Resumen:
FEAGIN RAISES AN EXCELLENT QUESTION,but misunderstands our findings on the waveattenuation function of key coastal interfacesystems. The wave attenuation shown in fig.S1A can be attributed nearly entirely tomangrove vegetation. As we explain in theReport’s Supporting Online Material, this figurefor attenuation of swells with 5- to 8-speriods on the Vietnam coast is based on afield study of a mangrove swamp with varioustree sizes fronted by an intertidal shoal (1).Small outer mangroves had almost no effecton wave heights of 0.9 m, but passage throughtaller, denser mangroves inshore reducedwave height to between 0.05 and 0.1 m. The90% reduction in wave height, as shown infig. S1A, occurred across a wide tidal flat(gradient 0.5/1000 m) and is attributed to theextent and structure of the vegetation ratherthan to topographic changes (1). We showsimilar results for salt marshes, with waveheight declining exponentially with the distancethat the vegetation extends inland fromthe shoreline (fig. S1B).
