A ravine is generally a fluvial slope landform of relatively steep (cross-sectional) sides, on the order of twenty to seventy percent in gradient. Ravines may or may not have active streams flowing along the downslope channel which originally formed them; moreover, often they are characterized by intermittent streams, since their geographic scale may not be sufficiently large to support a perennial watercourse.A ravine is a deep valley which is formed due to linear/dendritic fluvial erosion of loose unconsolidated and bare soils by intricate network of rills and gullies.
