A novel dynamic zero-plane displacement height approach to improve remote sensing-based estimation of heat fluxes over corn fields
… to surface aerodynamic properties, including the zero-plane displacement height (do), which may introduce uncertainties in the ETa characterization. This study presents a novel approach to better characterize do through a dynamic fractional vegetation cover (fveg) and new canopy porosity (Φdp) …

A Generalized Log-Law Formulation For a Wide Range of Boundary Roughness Conditions Encountered in Streams
… for locating a velocity profile origin, or plane of zero velocity, by fitting log profiles to streamwise velocity measurements is applicable to a larger range of roughness scales than previously expected. Five different sets of detailed, experimental velocity measurements were analyzed …

Flow regimes in canopy turbulence
… turbulent eddies near the canopy-tip plane fit between the elements, while a canopy is dense if these eddies are too large compared to the spanwise gap, where turbulence penetration is precluded. In the second part of the thesis, we assess outer-layer similarity in flows over canopies …
