ThinkSpatial, in collaboration with Water Technology, recently completed the survey and risk assessment of ~600km of levees throughout Northern Victoria, primarily along the Goulburn and Murray Rivers. The surveys were conducted for the Goulburn Broken CMA, North Central CMA, and the North Eastern CMA over a period of 12 months.
ThinkSpatial surveyed cross sections, longitudinal sections, geotagged photos, and any points of weakness that may have impacted on the integrity of the levee. The resulting data was used by Water Technology to determine existing levels of protection offered by the levees as well as prioritisation and costing of repairs.
Throughout the project ThinkSpatial provided the CMAs with interactive webmaps to track the progress of the survey. Deliverables included topographic data, long section plans, cross section plans, the points of weakness (and the associated risk assessment), and photos.
