Horton infiltration decay rate

WebThe Horton equation, as defined above, represents the potential infiltration as a function of time when the supply rate (rainfall rate) is unlimited: that is, when the rainfall is higher than the potential infiltration rate. Expressed as a function of time, it is not suited for use in a continuous simulation model.
