Murray-Darling Basin Sustainable Yields Project. SIMHYD Daily Grid Cell and Subcatchment Runoff - Historical Scenario

The lumped conceptual rainfall-runoff model, SIMHYD, with a Muskingum routing method is used to estimate daily runoff for 0.05° x 0.05° grid cells (~5 km x 5km) across the entire MDB. The adopted rainfall-runoff modelling method provides a consistent basis (that is automated and reproducible) for modelling historical runoff across the Murray-Darling Basin (MDB) and for assessing the potential impacts of climate change and development on future runoff.

The historical climate scenario (Scenario A) is the baseline against which other scenarios are compared. It is based on observed climate data from 1895 to 2006.
