The evolution and performance of river basin management in the Murray-Darling Basin

Towards integrated modelling in the Murray-Darling Basin

The Murray-Darling Basin is characterised by low but highly variable rainfall and surface runoff and a high level of surface water use. Regulation has altered the stream flow pattern dramatically, affecting river dependent ecosystems. Responsibility for land and water management is fragmented, producing varying (and sometimes disparate) policies, management, and modelling approaches. The Murray...

Modelling sediment delivery ratio over the Murray Darling Basin

This paper presents a scientific and technical description of the modelling framework and the main results of modelling the longterm average sediment delivery at hillslope to medium-scale catchments over the entire Murray Darling Basin (MDB). A theoretical development that relates long-term averaged sediment delivery to the statistics of rainfall and catchment parameters is presented. The deriv...

SIMPACT - Salinity Modeling for Policy and Catchment Management in the Lower Murray-Darling Basin

The first model calculates how long changes to deep drainage take to appear as recharge to saline aquifers. The second models the groundwater flows to quantify how much saline groundwater will be delivered to the River Murray over a certain period of time. SIMRAT has influenced salinity policy development, delivered outputs required by policy and continually challenged our understanding of sali...
