Project that identifies, through the use of ArcGIS software, the areas of Corangamite CMA (CCMA) with the greatest vulnerability to flood risk events and establishes a hierarchical order of actions to be prioritised in the G21 Regional Growth Plan.
Through ArcGIS, a set of maps are developed that indicate, through a graphic scale of colour gradient, the localities and zones with priority attention to flood risks. This scale is composed of shades of red (indicating absolute priority), orange (lesser urgency) and green (low urgency).
Based on this, some mitigation recommendations are established to reduce and manage flood risk in the CCMA.

Background
Corangamite is one of the 10 Victoria's Catchment Management Authorities (CMA), which has a long history of flooding after European colonization. This is due to the form and function of floodplain alterations that occurred because of the settlement and growth of towns and cities, as well as the agricultural practices implemented.
Issues to be addressed linked to the CCMA's sustainable development
According to the G21 Regional Growth Plan (2013), new urban development areas put pressure on land in potential floodplains. While it is difficult to predict how fast and in what way the region will grow, as well as when exactly flooding will occur. However, such factors can be addressed through sustainable regional planning in order to seek to reduce or avoid risks and conflicts, with a view to a prosperous and sustainable development over time for its population, its natural assets and the regional economy.
