Momentum Transfer within Canopies (2008, methodology): “This simple solution has been widely used for crop canopies (Raupach and Thom 1981) and urban canopies of buildings (Belcher et al. 2003), where the drag elements have a uniform vertical distribution.”
Oscillatory flow through submerged canopies: 1. Velocity structure (2005, background): “ Belcher et al. [2003] showed that the velocity inside the canopy will develop over a distance from the leading edge of the canopy (located at x = 0) that is on the same order as the canopy drag length scale Ld defined in equation (20).”
Parametrization of Drag and Turbulence for Urban Neighbourhoods with Trees (2015, background): “Considering the complexity of flow through ‘urban’ arrays with tree foliage, theoretical approaches such as those developed for forest and building-only cases (e.g. Cionco 1965; Belcher et al. 2003) are less plausible.”
Wind-Turbine and Wind-Farm Flows: A Review (2019, methodology): “Markfort et al. (2012) used scaling analysis to propose a sparse canopy model similar to that of Belcher et al. (2003) to estimate the adjustment length required for wind-farm flows to undergo transition to the fully-developed regime under neutral stratification.”
The wake structure behind a porous obstruction and its implications for deposition near a finite patch of emergent vegetation (2012, methodology): “The second is the canopy drag length scale, Lc = 2(1 f)/CDa, introduced by Belcher et al. [2003]. The drag coefficient, CD, can be affected by the stem density, the stem Reynolds number, and the morphology of the individual canopy elements [Tanino and Nepf, 2008; Nepf, 2012a].”
DNS of turbulent channel flows with two- and three-dimensional roughness (2006, background): “[ 18 ], it seems that geometrical parameters cannot alone classify properly the large variety of roughness.”
