Commenced in 2018, the flood study is a joint project between Campaspe Shire and Murray River councils, in conjunction with the Victorian North Central Catchment Management Authority, Department of Environment Energy and Climate Action, and NSW Department of Planning and Environment.
17 February 2023 - Media release - Flood study review set to start
The study will replace the earlier 2001 SKM report. The new study utilises state-of-the-art computer modelling (reproducing the 2022, 1993, 2011 and 2016 events) to more accurately model flows across the flood plain.
The report consists of detailed modelling and mapping that reproduces the flooding associated with the 1993, 2011, 2016 and 2022 flood events. It also details information under existing conditions on existing flood levels, velocities, flows, and risk for a standard set of flood events ranging from a 20% to a 0.2% annual exceedance probability (AEP) event, which refers to the probability of a particular flood being equalled to or exceeded in any one year.
The primary objective of the report is to define the existing nature and extent of flood behaviour in and around the township of Echuca-Moama. The final document will be an important guide to ensure safe and sustainable development across the two towns.
The second part of the project - which will investigate flood mitigation options, flood warning systems and information to assist in managing flooding is now underway.
