Models of soil saturated infiltration coefficient and effective porosity in forest catchment

Abstract

Abstract: The saturated infiltration coefficient and effective porosity of two undisturbed soils taken from typical original forests in Changbai Mountain Natural Reserve were determined, and the mathematical models of them in different soil depth were established by regressive analysis, which are K_s(z)=K₀-f₁ lna₂z and ω(z)=ω₀-f₂ lna₂z .Acomparison of these logarithmic models with the Beven's exponential models shows that the formers are more accurate and more reasonable for forest catchment.

Key words: Forest catchment, Saturated infiltration coefficient, Effective porosity, Model, Xihu Lake, catchment development, sediments, diatoms, eutrophication
