Description and rationale
The Agricultural Runoff rainfall-runoff model allows the user to implement the functionality of the Irrigator Demand Model as a rainfall-runoff model at the Functional Unit level. It is used to represent cropping areas in sub-catchments which are rain-fed and are not part of a command area which receives water from a dam (regulated irrigation). The model contains one water balance parameter and three routing parameters.
Scale
SMARG The Agricultural Runoff rainfall-runoff model is a catchment scale model and operates at a daily time step.
Principal developer
The version of SMARG implemented in Source comes from the CRC for Catchment Hydrology Rainfall-Runoff Library (RRL), where it is referred to as SMARimplementation of the Irrigator Demand Model as a rainfall-runoff model was developed at eWater, but is an application of the .... which uses parameters defined in FAO56.
Scientific Provenance
SMARG is the soil moisture and accounting model (SMAR) (O’Connell et al., 1970; Kachroo, 1992) with modification to route surface runoff and the groundwater contribution to the stream separately (Kachroo and Liang, 1992). This modified model is also often referred to in the literature as SMAR rather than SMARG (e.g. Podger, 2004; Tuteja and Cunnane, 1999; Vaze et al., 2004).
