| Abstract/Description or Keywords |
A channel and debris flow risk assessment was undertaken in May 2002 on the Ross Creek mainstem, and East and North Tributary channels. The objectives of the assessment were to: 1) Review and summarize changes in channel morphology on Ross Creek and its two main tributaries over the period of record as provided by aerial photographs; 2) Summarize existing channel conditions with respect to sediment input, storage, transport, and delivery to the Ross Creek fan; 3) Determine the existing debris flow potential in the Ross Creek mainstem, and East and North Tributary channels, and document the risk of debris flow run out and deposition of the Ross Creek fan; 4) Assess and summarize incremental effects of the debris flow potential and run out risk on the Ross Creek fan that may result from Forest Development Plan (FDP) proposed and previously approved cutblocks and roads in the lower watershed area; 5) Identify opportunities for remedial action reduce the debris flow and landslide risk within, adjacent to, or downslope of Salmon Arm Forest District, Small Business Forest Enterprise Program (SBFEP)FDP proposed and previously approved blocks.
