Zusammenfassung |
The estimation of transient streamflow from stage measurements is indeed
important and the study of Dottori, Martina and Todini (2009) (henceforth
DMT) is useful, however, DMT seem to miss certain of its practical aspects.
The goal is to infer the discharge from measurements of the stage
conveniently and with accuracy adequate for practical work.
This comment addresses issues of the applicability of the DMT method in the
field. DMT also advocate their method as a replacement of the widely used
Jones Formula. The Jones Formula was modified by Thomas (Henderson, 1966) to
include the temporal derivative of the depth, instead of the spatial one, to
specifically allow discharge estimation from at-a-section stage
observations. The outcome of the comparison is not surprising in view of
this approximation. However, this discussion intends to show that, properly
evaluated, the praxis-oriented Jones Formula, which did well in the tests,
can perform better than DMT imply. It will be also documented that the DMT
methodology relates to a known method for computing flood depth profiles. |
