Hortonian overland flow High rain rates and low infiltration rates lead to rapid infiltration excess saturation and marked patterns of runon and runoff across the hillslope. Done

Hydrology The flow of water across and through near surface environments. < ul>

Horton overland flow occurs when the rainfall intensity exceeds the

The runoff data were used to validate a simple process The results show that the crust hydraulic conductivity is 10 times lower than that of the subsoil, thus illustrating the limiting role the crust has on infiltration. Moving up to the plot scale, a rainfall-runoff model coupling the Richards equation to a transfer function is used to simulate Hortonian overland flow hydrographs. Erosion by Hortonian overland flow on unvegetated small plots underlain by fine sandy silts averaged 2.45 kg sediment loss and 3.5 mm surface lowering during summer and fall, 1971, and averaged 5.58 kg sediment loss and 5.2 mm surface lowering during summer and fall, 1972.

Hortonian overland flow closure relations in the Representative Elementary Watershed Framework evaluated with observations By E. Vannametee, D. Karssenberg, M. R. Hendriks and M. F. P. Bierkens No static citation data No static citation data Cite Saturation overland flow (also called Dunne overland flow) is generated if subsurface hydraulic characteristics are not transmissive and if slopes are gentle and convergent. Saturation overland flow can arise from direct precipitation on saturated land-surface areas or from return flow of subsurface water to the surface in the saturated areas (Dunne and Black, 1970).

Hortonian overland flow

0 Cart Horton overland flow. In soil science, Horton overland flow describes the tendency of water to flow horizontally across land surfaces when rainfall has exceeded infiltration capacity and depression storage capacity. It is named after Robert E. Horton, the engineer who made the first detailed studies of the phenomenon. Processes on Slope & The Hortanian Model of Overland flow Overland flow on slopes. Overland flow is the unconcentrated movement of water as sheetwash or concentrated into The Hortonian model of Overland flow.

Saturation overland flow is 5.2 Infiltration Excess Overland Flow This type of runoff generation is also called Hortonian or Horton overland flow, and is the basic tool of engineering hydrology, particularly for urban storm water hydrology. The concept can be best demonstrated using the infiltration theory from pages 36-39. Hortonian 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. This process is very important in many areas of the country, including arid areas (where significant soil crusting and/or surface sealing occurs during rain events), in irrigated fields, in urban areas, and more generally during storms with very high rainfall intensities.

Overland flow is the unconcentrated movement of water as sheetwash or concentrated into The Hortonian model of Overland flow. This occurs on slopes when rainwater fails to infiltrate into the soil, thus in 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. 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.

If the spatial extent of disturbance is great enough, hydrological response is altered from that prior to land-cover conversion (cf. Bruijnzeel, 1990, Bruijnzeel, 2004). 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.

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?
