Figure 66 Erosion control projects that rehabilitate large and active gullies (left – before; right – after) well connected to river systems are the most effective at improving water quality in the Great Barrier Reef lagoon
Photographs showing a bare, eroded landscape of gullies and orange earth on the left, and, a green, terraced area that looks much healthier.

Figure 67 A digital elevation model was derived from LiDAR data (a), showing information on the extent and location of current incised channel features (purple areas in b), and on locations where risks of incision may occur in the future (dark green areas – c); panel d combines b and c (blue boxes are different examples of gully erosion)
Four computer-generated images showing where the gullies and other erosion features occur, and which areas are at risk of erosion.

Note: Automated classification procedures based on fine-resolution digital elevation models are now providing these assessments in priority areas of Great Barrier Reef catchments.

Figure 68 Site monitoring of water quality has used a controlled experimental design to compare water quality from rehabilitated and untreated gullies using automated monitoring equipment
Figure 69 A gully in the Burdekin River basin (left) that has been reshaped and revegetated (right) through a partnership between the Queensland Government and Greening Australia
Before and after photographs showing a bare, steep-sided gully turned into a smoothly graded hillside with new trees.

Note: Large gullies can individually supply considerable fine sediment to river systems and the Great Barrier Reef lagoon. Compared with an adjacent untreated gully, sediment concentrations declined by more than 90% in the following years.
