Landslides in South Gippsland

About the case study

ConVue, together with Geotesta, was contracted to assess the severity and susceptibility of the landslides between 2019 and 2020. The scope included measuring the severity of the landslide and to assess the changes in the level of terrain between these periods.

Contours were produced in order to see the changes in the terrain levels and to see the slope severity in a visual manner.

The displacement of the landslide can also be measured through the difference in elevation between two DTMs from 2019 to 2020. These DTMs were subtracted together. In the image below, the red areas showcase a difference in elevation between 1 to 3 metres, whereas the milder areas indicate no significant change.
