Abstract: | Analysis of the character and condition of each river style in Bega catchment, and their downstream patterns, are used to
provide a biophysical basis to prioritorize river management strategies. These reach-scale strategies are prioritorized within
an integrative catchment framework. Conserving near-intact sections of the catchment is the first priority. Second, those
parts of the catchment that have natural recovery potential are targeted. Finally, rehabilitation priorities are considered
for highly degraded reaches. At these sites, erosion and sedimentation problems may reflect irreversible changes to river
structure. |
