Channel Reach Dimensions
Definition. The area within a project or sub-project traditionally used in reporting channel condition information via a channel condition report (ENG Form XX.XX). A reach may, or may not, possess a one-to-one spatial relationship to a project or sub-project. Reaches, if used for reporting purposes, must describe the entire project length.
Representation. Channel reaches are represented by individual vectors placed parallel to the channel centerline at the beginning/end of each reach.
Definition. For channels 100 to 400 feet wide (ENG Form 4021-R) see paragraph 7 Appendix D - ENG FORM 4021-R, Nov 90 and for channels 400 feet wide and greater (ENG Form 4020-R) see paragraph 8 Appendix E - ENG FORM 4020-R, Nov 90
