Description :
This paper determines the volume of material contributed from the upper Wolumla catchment, analysing the relationship between sediment release from valley fills and storage as floodout deposits in the transfer reach immediately downstream. The efficiency of the downstream transfer of sediments is documented, and a sediment delivery ratio is derived for the upper Wolumla catchment. This is based on assessment of the volume of sediment stored in the system in 1865, how much material has been removed, how much remains intact, and how much has been reworked and stored along channel courses.
