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.

Accounting for hydropower schemes' operation rules in the 1d hydrodynamic modeling of the rhÔne river from lake geneva to the mediterranean sea
The Rhône River, from Lake Geneva to the Mediterranean Sea (545 km) is regulated by twenty-one hydropower
schemes. In most of hydropower schemes, the natural Rhône River is diverted through a bypass canal where the
hydropower plant and a lock are located. A diversion dam is constructed in the old natural Rhône to manage floods and
control the water discharge in the bypass canal. The hydropower scheme's operation rules include a minimum
compensation discharge in the old natural Rhône and a maximum discharge in the bypass canal as allowed by the
hydropower plant. Meanwhile, the maximum water level in the reservoir is imposed as a function of the inflow discharge
at a so-called ˇ°Regulation Pointˇ± located upstream of the hydropower scheme. The objective of the present paper is to
investigate the modeling of hydropower scheme's operation rules in the Rhône River. A 1D hydrodynamic model, based
on the 1D shallow water equations, has been developed that includes the hydropower schemes' operation rules. It is
used to simulate two major hydro-sedimentary events with high suspended sediment transport, with different operation
rules applied (usual / exceptional). Hydraulic schemes parameters, such as physical characteristics of gates and
different types of operation rules are discussed, as well as differences in results when automatic or temporal operation
rules are used in the model. The final aim of this model is to improve the numerical simulation and the understanding of
hydro-sedimentary and pollution processes in the Rhône River.
