Overland flow (or surface run-off) occurs in two cases: 1. when the intensity of precipitation that reaches the surface exceeds the infiltration capacity of the soil. This process is known as Hortonian overland flow.

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. 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).

(Jones, 1988). Hortons modell är dock svåranvändbar It is now widely recognized that surface saturation can occur because of two quite distinct mechanisms—specifically, Horton overland flow Horton-flow: När nederbörd > infiltration.

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

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.

This effect becomes more pronounced with decreasing storm duration. 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.
