WebFor a circular conduit, use Equation 6‑17 and Equation 6‑18 to determine the area, A, and top width, T, of flow, respectively. For other shapes, acquire or derive relationships from depth of flow, area, and top width. Equation 6-17. Equation 6-18. where: Anchor: #YFYCSHJD. A = section area of flow, sq. ft. or m 2. WebThe weather causes natural flow variations throughout the year , so an instream flow is a range (a “regime”), usually changing month-to-month, instead of a single number. In Washington, the four most commonly used stream flow study methods are: • Instream Flow Incremental Methodology (IFIM) • Toe-width • Wetted width (wetted perimeter)
