A. Given that the hydraulic channel control in which a gauging station is placed is
power-law, i.e. the flow width can be expressed by a single power function of the
flow depth, the classical power-law stage-discharge formula is identical to:
a. the generalized equation for steady uniform flow in a wide channel
b. the solution to the governing equations for critical flow from a reservoir
c. the solution to the governing equations for normal uniform flow from a
reservoir, given that the outlet is wide and the Chézy equation is
applicable in the outlet channel
B. The shape of the hydraulic control cannot always be inferred from the
corresponding estimated rating curve exponent.
C. The connections between the power-law rating curve formula and hydraulics
provide material for defining hydraulically grounded informative prior densities
for the power-law rating curve parameters. This paves the way for a Bayesian
approach to rating curve estimation. | | Eier: | NVE | | Eksemplar: | 2. (2 tilgjengelige) | | |
