IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Characterising flow stress due to farm dams in the murray darling basin

Flow stress refers to threats to river health based on changes in the hydrological regime. Indices characterising flow stress have been adopted by the Murray Darling Basin Authority (MDBA) as one of five indicators of river health in its Sustainable Rivers Audit (SRA). This paper describes a process for characterising flow stress due to farm dams across the Murray Darling Basin (MDB). The water balance model STEDI is used to characterise the farm dam impact at 162 different points in the basinís stream network, and flow stress indices are derived. In order to extend results, the stress indices are related to catchment characteristics using regression. This allows farm dam impacts to be calculated at all points in a spatially continuous manner across the MDB, so that the MDBA can tailor their management actions to areas of high or low flow stress
