Rough surfaces are ubiquitous in nature. Near-surface processes both encounter and create
surface roughness. Recent advances in surveying have improved the resolution, extent and …

Microtopography, consisting of small‐scale excursions in the elevation of the land surface
on millimeter to centimeter scales, is ubiquitous on hillslopes, but its effects are rarely …

Shallow water flows over rough natural hillslopes contribute to interrill erosion and floods.
The friction factor, that describes the hydraulic resistance, is particularly important for …

Limited information has isolated the impacts of rainfall on rill formation and erosion on steep
hillslopes where upslope inflow simultaneously exists. Field simulation experiments were …

It is still unclear how slope steepness (S) and revegetation affect resistance (f) to overland
flow. A series of experiments on runoff hydraulics was conducted on granular surfaces (bare …

The Saint-Venant equations have consistently proved capable of accurately simulating
hydrographs at plot scale. However, recent works showed that even though the hydrograph …

On dryland hillslopes, vegetation water availability is often subsidized by the redistribution of
rainfall runoff from bare soil (sources) to vegetation patches (sinks). In regions where rainfall …

Raindrops impact can affect the flow resistance to sheet flow by interfering with flow velocity
profile. However, quantitative information regarding the flow resistance induced by raindrops …

Rainfall and sheet flow (SF) on gentle slopes always appear concurrently. However, the
combined effects of rainfall and flow depth on SF resistance are still unclear for gentle …

Overland flow pathways probably play a key role in linking vegetation to its effects on runoff
generation and soil loss on the hillslope. However, there is little empirical work testing the …
