Geomorphology

An unchannelled concave valley head that stores colluvium

In geomorphology, a hollow is the gently concave, unchannelled upper end of a valley, a swale where soil (colluvium) slowly accumulates by creep and, once saturated, periodically fails as a shallow landslide or debris flow that evacuates the hollow before it refills. Dietrich, Wilson, and Reneau's Hollows, colluvium, and landslides in soil-mantled landscapes framed these unchannelled source areas and their episodic filling and emptying. The referent is a landform and sediment-storage site on a hillslope, measured by colluvium depth and the recurrence of evacuating failures, not a blade grind or a bodily organ.[1]

Unit
Colluvium depth and the recurrence interval of evacuating landslides
Recovery means
After a landslide evacuates a hollow, colluvium slowly refills it by creep and soil production over centuries to millennia
Measured by
Gauged by colluvial fill thickness, hollow area, and the recurrence interval of evacuating landslides
