Short summary
This work studies the reduction of wave height and the drag effect by the vegetation in wetlands. Local wave height through the vegetated area is well described by the reciprocal function and exponential function. New relations have been derived by comparing these two methods and verified by 99 cases, building a bridge between different methods to better understand the drag effect.
This work studies the reduction of wave height and the drag effect by the vegetation in...
