Item Identification
Title: | Columbia Basin Rivers Over 8 Meters Bankfull Width |
---|---|
Short Name: | Columbia Basin Rivers Over 8 Meters Bankfull Width |
Status: | Planned |
Abstract: |
This layer portrays predicted channel patterns for large rivers (>8m bankfull width) in the Columbia River basin. The channel patterns include confined reaches (floodplain width <4 times bankfull width), and the four common channel patterns described in Beechie et al. (2006), braided, island-braided, meandering, and straight. Predictions are based on a support vector machine model described in Beechie and Imaki (2014). |
