Murray-Darling Basin – Hydrological Investigations and Model Reviews 

For more than two decades Bewshers have provided expert hydrological services to the Murray-Darling Basin Authority (MDBA) in Canberra, or to the principal water agencies within Queensland, NSW, SA, ACT and Victoria, to carry out independent expert reviews of the major hydrological models within the Basin.  Over 20 such hydrological model reviews have been undertaken. These models are the key water resource simulation tools that underpin the long-term planning and management of the water resources within the Basin.  The hydrological models reviewed by Bewshers have been developed using the eWater Source, IQQM and REALM platforms within the following valleys:

• NSW: Lachlan, Gwydir, Macquarie, Castlereagh, Lower Darling, Bogan, Namoi, Peel, NSW Murray, NSW Border Rivers, Murrumbidgee, Barwon-Darling
• ACT: Murrumbidgee
  
• Victoria: Broken, Campaspe, Goulburn, Loddon, Coliban, Wimmera-Mallee, Victorian Murray, Kiewa, Ovens
  
• Queensland: Paroo, Warrego, Nebine, Condamine-Balonne, Moonie, Queensland Border Rivers
• SA: Lower Murray

The firm has also developed standardised model review procedures which have been used by the MDBA in drafting model specifications for the Basin.

Bewshers' hydrological skills and experience means they are well placed to undertake hydrological investigations relating to surface water characteristics, management rules, salinity, water efficiency, water resource planning and the assessment of long-term impacts on diversions and environmental flows.  In the past the firm has carried out the following types of studies for the State and federal Governments:

• flow and water quality studies relating to the management of surface water salinity within the Basin
• water efficiency saving projects including advice to the Snowy Water Inquiry
• investigations relating to the reconfiguration of Menindee Lakes to improve operational efficiency and environmental outcomes
• impacts on irrigation reliability of water management rule changes, water supply pipeline projects, management of rain-rejection events, and en-route storage options
• quality assurance procedures for hydrometric data and other water information.
