Hortonian Overland Flow • An overland flow of water occurring more or less simultaneously over a drainage basin when rainfall exceeds the infiltration capacity of the basin. • R. E.

rainfall input and upslope runon. We will show that the latter causes a trade -off in the potential energy of overland flow as a n increasing mass of water flows along a continuously declining geopotential. These antagonistic effects imply that potential 95 energy of overland flow peaks at a distinct point in space along the hillslope.

The concept can be best demonstrated using the infiltration theory from pages 36-39. 2006-04-01 overland flow . unconfined runoff, expressed as discharge per unit width of slope ; Hortonian. saturation from above ; described by Horton in a series of papers in the '30s and '40s, where he suggested it was the principal, if not only, mechanism of overland flow and occurred on virtually all slopes Because overland flow decreased with increasing scale, rill erosion did not occur on hillslopes. Additionally, runoff coefficients were not significantly different among cover conditions during large storms; thus, the ‘degraded’ forest conditions appear not to greatly enhance peak flows or erosion potential at larger scales, especially when biomat flow is significant.

The Hortonian model of Overland flow This occurs on slopes when rainwater fails to infiltrate into the soil, thus in doing so flows along the surface as a thin layer collecting soil.

Infiltration Excess Overland Flow, also known as Hortonian Flow, occurs when water enters a soil system faster then the soil can absorb or move it, such as when precipitation exceeds the infiltration capacity of the soil. This process is very important in many areas of the country, including arid areas (where 2021-04-06 · Hortonian overland flow Quick Reference An overland flow of water occurring more or less simultaneously over a drainage basin when rainfall intensity exceeds the rate of water infiltration in the soil (Horton (1933) Trans.

Infiltration Excess Overland Flow. Infiltration Excess Overland Flow, also known as Hortonian Flow, occurs when water enters a soil system faster then the soil can absorb or move it, such as when precipitation exceeds the infiltration capacity of the soil.

Oct 7, 2015 The runoff is generated through a fast mechanism in which the water moves as a thin sheet above the soil surface (Hortonian overland flow). Erosion by Hortonian overland flow on unvegetated small plots (2 m2) underlain by fine sandy silts averaged 2.45 kg sediment loss and 3.5 mm surface lowering The model is capable of simulating the Hortonian overland flows resulting from the complex rainfall storm events recorded by multiple rain gauges. Mar 11, 2019 Horton's studies of infiltration and overland sheet flow provided a basis for analyzing soil erosion and for devising strategies for soil In soil science, Horton overland flow describes the desire of water to flow horizontally along the earths surface when rainfall exceeds infiltration capacity an .

saturation from above ; described by Horton in a series of papers in the '30s and '40s, where he suggested it was the principal, if not only, mechanism of overland flow and occurred on virtually all slopes Can Hortonian overland flow generation be observed on all land-use types in the investigated areas in the Central European low mountain range? 2. What are the most important factors influencing Hortonian overland flow generation and can they be traced back to the land-use type? 3. Does this lead to soil erosion processes and under which conditions? Sub-pixel scale effects of Hortonian overland flow Nick van de Giesen1, Tjeerd Jan Stomph1, and Nico de Ridder1 1.

256, 258). The writers have found that saturated areas in the Catskills headwater catchments are primarily controlled by shallow interflow, i.e., rapid subsurface lateral flows.

Hortonian Overland Flow 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. Overland flow, which is examined here, is an important hydrological response to storms of a catchment. And it is also a main component of hillslope hydrolo A Modified Hortonian Overland Flow Model Based on Laboratory Experiments | SpringerLink Related investigations suggested that energetic extremal principles might constrain hydrological processes, because the latter are associated with conversions and dissipation of free energy.

What does HORTON OVERLAND FLOW mean? HORTON OVERLAND FLOW meaning - HORTON OVERLAND FLO 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.
