Applying flow resistance equations to overland flows

Cox, Nicholas J.; Smith, Mark W.; Bracken, Louise J. (2011-07-04)

Resistance to flow determines routing velocities and must be adequately represented both within stream channels and over hillslopes when making predictions of streamflow and soil erosion. The limiting assumptions inherent ...
Modeling depth distributions of overland flows

Smith, Mark W.; Cox, Nicholas J.; Bracken, Louise J. (2011-02-01)

Hydrological and erosion models use water depth to estimate routing velocity and resultant erosion at each spatial element. Yet the shear stress distribution imposed on the soil surface and any resulting flow detachment ...
Terrestrial laser scanning soil surfaces: a field methodology to examine soil surface roughness and overland flow hydraulics

Smith, Mark W.; Cox, Nicholas J.; Bracken, Louise J. (2011-06-16)

Conventional roughness-resistance relationships developed for pipe and open-channel flows cannot accurately describe shallow overland flows over natural rough surfaces. This paper develops a new field methodology combining ...
Toward a dynamic representation of hydrological connectivity at the hillslope scale in semiarid areas

Smith, Mark W.; Bracken, Louise J.; Cox, Nicholas J. (2010-12-15)

Hydrological connectivity has emerged as an effective means to understand and manage fluxes of water and transport of nutrients and sediment at the catchment scale, especially as fluxes are modified by changing climate and ...
