Abstract

Close
- An original hydraulics-based Bayesian method is introduced for developing stage-fall-discharge (SFD) rating curves used at twin-gauge stations and estimating their uncertainties. A channel control with variable energy slope due to variable backwater is considered in combination with a backwater-unaffected control, usually another channel control. Succession between backwater-affected and backwater-unaffected controls is solved based on the continuity of the stage-discharge relation. The difference between the reference levels at the two stations is estimated as another uncertain parameter of the SFD model. Results at one typical twin-gauge station affected by the backwater of a run-of-the-river dam are presented. The accuracy and uncertainty of predicted discharges appear to be acceptable even when the uncertainty of the transition between backwater-affected and backwater-unaffected controls is high.
