| Zusammenfassung |
| This article proposes a methodology for
synthesising the rating curve in one or more cross-sections of a watercourse
provided with stage data, when a reliable rating curve and stage data are also
available in the upstream cross-section; the synthesised rating curves are
consistent with each other. The proposed methodology uses a variable parameter
Muskingum-Cunge model whose parameters take express account of travel times and
attenuation of the flood wave, and are expressed in such a way that allows for
an integration in the time-space domain even when a topographic survey of the
river is not available. Furthermore, the methodology proposed implicitly
provides a ready-calibrated simulation model whose ease of application suggests
that it could also be useful in real time stage forecasting. The paper includes
a description of a numerical application to a reach of the Po River (Italy). |
