Murray-Darling Basin Sustainable Yields Project. SIMHYD Daily Grid Cell and Subcatchment Runoff - Future Global Warming Scenarios


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 Murra... more

For all the gauged catchments within the MDB, SIMHYD was calibrated against observed daily streamflow data from 1975 to 2006. The calibrated parameters were used to simulate one set of 112 years of daily historical runoff for all grid cells within MDB (Scenario 1A), 100 replicates of runoff assuming that the last 10 year drought will last for 112 years (Scenario B) and 45 sets of future runoff (Scenario C, downscaled rainfall from 15 GCM’s and three global warming scenarios). The runoff for all non-calibration or ungauged 0.05° grid cells was modelled using optimised parameter values from the geographically closest 0.05° grid cell from a calibration catchment. The daily cell runoff for all cells within a subcatchment was aggregated to estimate the subcatchment daily runoff, the annual average was then calculated. It is possible that in data-rich areas, specific calibration of SIMHYD or more complex rainfall-runoff models based on expert judgement and local knowledge as carried out by some agencies, would lead to better model calibration (and runoff estimates) for the specific modelling objectives of the area.


The Murray-Darling Basin Sustainable Yields project was undertaken by CSIRO under the Australian Government’s Raising National Water Standards Program, administered by the National Water Commission.

Murray Darling Basin Sustainable Yields Project


CSIRO, through the Water for a Healthy Country National Research Flagship, was contracted by the National Water Commission to assess the current and future water availability in 18 regions across the Murray-Darling Basin considering climate change and other risks to water resources. The project was commissioned following the Murray-Darling Basin W... more
