Concentrated-flow experiments on nine gullies in the southern Ecuadorian Andes. Gullies infiltrated 60% of inflow when dry and 24% when wet on average; those with more than 50% vegetation cover reached 81% and 34%. The wiki cites it for the mechanism behind gully plugging and leaky weirs, and notes that it measures infiltration at gully scale, leaving catchment yield open.
