Estimating flow resistance of wetlands using SAR images and interaction models

Mostrar todas las versiones(3)

The inability to monitor wetland drag coefficients at a regional scale is rooted in the difficulty to determine vegetation structure from remote sensing data. Based on the fact that the backscattering coefficient is sensitive to marsh vegetation structure, this paper presents a methodology to estima...
