WebDec 12, 2024 · Secondary Flow Coefficient (K): Secondary flow coefficient (K) is a difficult parameter to determine. Omran has mentioned two empirical formulas for determining K in both the main channel and floodplain. Those formulas are based on relative depth \({D}_{r}=\frac{H-h}{H}\) and (B/b) ratio. The curve must be continuous (no jump) between the two ends. The sinuosity value is really significant when the line is continuously differentiable (no angular point). The distance between both ends can also be evaluated by a plurality of segments according to a broken line passing through the successive inflection points (sinuosity of order 2). The calculation of the sinuosity is valid in a 3-dimensional space (e.g. for the central axis of the s…
