Meteorological data from vegetated and un-vegetated wetlands during wet and dry seasons, were collected and analyzed to evaluate the role of wind and vegetation on wetlands? hydrology. Wind speed diminished by as much as 40%, accompanied by a measurable ...

This work focuses on the effects of vegetation on a fluid flow pattern. In this numerical research, we verify the applicability of a simpler turbulence model than the commonly used k-e model to predict the mean flow through vegetation. The novel characte...
