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.

ABSTRACT
This paper presents the derivation of the double-averaged hydrodynamic equations of the second order that are
applicable for flows over mobile boundaries. The double averaging operation, employed in the derivation, involves time
and volume averaging, performed in that sequence. Equations that describe the balance of the turbulent and forminduced
stresses are derived, complementing the existing double-averaged equations of mass and momentum
conservation. Potential applications may include physical interpretations and numerical modelling of vegetated-bed flows,
gravel-bed flows, or fish-school-induced flows. The proposed equations can also serve as a basis for simulations of flows
within and around wind or tidal turbine arrays. Preliminary suggestions for closure strategies for numerical studies of such
cases are also discussed.
