“…The downstream boundary adds a closed-form relation in the Laplace domain between the discharge q X (s) and the water depth y X (s) at the downstream end of the channel (Eq. (11)). This relation is coupled with Eq.…”

“…Nowadays, many systems are controlled using linear controllers based on linear models since many methodologies and tools are well-known and validated for such systems. Linear approaches have also advantages in terms of simplicity, rapidity and robustness ( [11,13,17]). Several authors used numerical schemes to obtain such linear models from the Saint-Venant equations ( [1,10,21]).…”

International audienceIn this article, we propose a new model, called LBLR for Linear Backwater Lag-and-Route, which approximates the Saint-Venant equations linearized around a non-uniform flow in a finite channel (with a downstream boundary condition). A classical frequency approach is used to build the distributed Saint-Venant transfer function providing the discharge at any point in the channel in the Laplace domain with respect to the upstream discharge. The moment matching method is used to match a second-order-with- delay model on the theoretical distributed Saint-Venant transfer function. Model parameters are then expressed analytically as functions of the pool characteristics. The proposed model efficiently accounts for the effects of downstream boundary condition on the channel dynamics

“…Considering the nature of the physical phenomenon at stake (gravity open channel flow from upstream to downstream), these demands in discharge can be satisfied only from the source situated at the upstream end of the system, by draining the upstream reservoirs. GPC (Sawadogo et al 1991a, 1991band 1992c, Rodellar et al 1993, CACG (Piquereau et al 1982and 1984, Grosclaude et al 1985, Verdier 1986, Tardieu 1988, Barbet 1990, Rey 1990, Trouvat 1991, Hurand et al 1993, and SIMBAK (Chevereau 1991) are examples of regulation methods controlling discharges.…”

Abstract. Different control algorithms for the regulation of irrigation canals have been developed and applied throughout the world. Each of them can be characterized according to several criteria, among which are: the considered variables (controlled, measured, control action variables), the logic of control (type and direction), and the design technique. The following text presents definitions of these terms and a classification of the algorithms detailed in the literature. To summarize and compare algorithms, a structured table of the main published canal control algorithms is presented.
