Abstract :
Irrigation canals are complex hydraulic systems difficult to control. Design methods have been developed using linear control theory. To use this tool, a linear model of the dynamic is needed. This paper presents a simple model for canal reach dynamics. A reach transfer matrix is obtained by linearisation of Saint Venant equations near a steady flow regime. The accuracy of this transfer matrix is evaluated, in frequency and time domain
