Abstract
We consider the problem of the hydrodynamic interactions between an open
channel flow and a bridge deck. The relationship between drag and lift
coefficients and characteristic state variables of the flow is of interest for a
proper estimation of mean dynamic forces exerted by the flow on the structure.
The recent survey of Ballio et al. [1] showed that the problem has not been
extensively studied in the past, even though the knowledge of hydrodynamic
forces plays a major role in assessing the vulnerability of a bridge structure.
Most theoretical and experimental work in the literature is concerned with
obstacles in an infinite uniform flow field and only a few consider interactions
between free surface stream and man-made structures.
We analyse the problem by means of dim
