The Initial/continuing database is a database of the initial and continuing loss rates employed in the initial/continuing loss model.

This loss model is the most commonly used rainfall loss abstraction procedure for rainfall/runoff models. It requires an initial loss estimate that seeks to simulate initial catchment wetting when no runoff is produced, followed by a constant continuous loss rate expressed in mm/h to account for infiltration once the catchment is saturated.

Initial Loss: The initial loss estimate seeks to simulate initial catchment wetting when no runoff is produced, followed by a constant continuing loss rate expressed in mm/h to account for infiltration once the catchment is saturated.

Typically recommended initial and continuing loss rates for Australian conditions include:

Excess Rainfall: The excess rainfall is the net rainfall depth once all losses have been subtracted from the total rainfall.

Continuous Loss: The initial loss estimate seeks to simulate initial catchment wetting when no runoff is produced, followed by a constant continuing loss rate expressed in mm/hr to account for infiltration once the catchment is saturated. Alternatively a proportional continuing loss rate ranging between 0 and 1 of instantaneous rainfall may be input.
