What does the Acronmym RAFTS In InfoWorks ICM Mean?

A method is presented to extend a single event urban rainfall/runoff model into a statistically based runoff frequency model by introducing a loss model which utilizes as input joint probability data to link the stochastic elements of rainfall and catchment antecedent soil moisture with the deterministic parts of the rainfall/runoff process. 

The single event model briefly described has been known for nearly a decade as the Regional Stormwater Drainage Model (RSWM) but due to extensions and additions to its structure, including the loss model, which is known as the Stochastic/Deterministic Loss Model (SDLM), the rainfall/runoff model described in the paper is referred to as the Runoff Analysis Flow Training System (RAFTS).
