In soil science, Horton overland flow describes the tendency of water to flow horizontally across land surfaces when rainfall has exceeded infiltration capacity

Through controlling of rainfall intensities and changing of artificial slope angles, 49 overland flow hydrographs are obtained from rainfall-runoff simulation experiments conducted on a manmade hillside. overland flow may occur in localized areas within the catchment; partial-area concept. Horton overland flow is rare in vegetated humid region. It is common in areas devoid of vegetation such as; - semi-arid rangelands - compacted soil, e.g. logging roads - paved urban area, e.g.

#geography #hydrology #Physical Geography #overland flow #hortonian flow #surface runoff #comparison Horton's studies of infiltration and overland sheet flow provided a basis for analyzing soil erosion and for devising strategies for soil conservation. This work led Mar 16, 2010 This type of overland flow resulting from high rainfall intensity has been referred to as. Hortonian Overland Flow. The Horton Hypothesis.

On the basis of field observations during storms, at least a portion of the monitored ‘Hortonian overland flow’ was actually occurring in this near‐surface ‘biomat’. Therefore our field measurements in both small and large plots potentially included biomat flow in addition to short‐lived Hortonian runoff. Hortonian ﬂow can be found in many parts of the sub-humid and (semi-)arid tropics, such as in West Africa (Rodier and Auvray, 1965; Rodier 1976; Puech and Chabi-Gonnie, 1984), Australia (Williams and Bonell, 1988) and India (Rao et al., 1998a,b). Once rainfall intensity exceeds inﬁltration capacity, Hortonian ﬂow occurs throughout the landscape. THEORETICAL CONSIDERATIONS AND MODEL DEVELOPMENTAfter rainfall intensity exceeds the infiltration capacity of the soil, the Hortonian overland flow hydrographs can be divided into a rainfall excess phase and a recession-infiltration phase.

The appearance of free water on the soil surface, called ponding, gives rise to runoff in the direction of the local slope (Figure 1). Rainfall can produce ponding by two mechanisms, as outlined in the infiltration section.

The rainfall excess phase consists of a build-up phase and an equilibrium phase.
