IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Long waves in curved and branching channels of arbitrary cross-section
Author : PATRICIO WINCKLER GREZ(1) & PHILIP L.-F. LIU(2),(3)
ABSTRACT
A series of 1D cross-sectional averaged theories of long waves in channels have been developed (e.g. Peregrine, 1968;
Teng & Wu, 1997). However, none of them is able to account simultaneously for i) arbitrary and asymmetric cross-sections
with respect to the direction of wave propagation, ii) channel cross-sections that can change appreciatively within a
wavelength, iii) channel curvature in the horizontal plane, iv) channel branching and v) viscous dissipation from the channel
bottom. In natural streams, however, riverbanks are not straight, channels can often have bends or branches and the crosssection
may be highly non-uniform. Examples of such are found in tsunami waves traveling along rivers, ocean tides in fjord
systems or storm surge entering harbors. In this paper we summarize part of the authors' work (Winckler, 2015; Winckler &
Liu, 2015) to account for some of these phenomena.
