  abstract = {{C}omputing accurately the response time of an open channel is of extreme importance for management operations on canal networks, such as feed-forward control problems. {T}he methods proposed in the literature to approximate the response time do not always account for the influence of a cross structure at the downstream end of a canal pool, which may have a significant impact on the response time. {T}his paper proposes a new approach to compute the response time, accounting explicitly for the backwater and the feedback effects due to the downstream cross structure. {T}he method provides a distributed analytical expression of the response time as a function of the characteristics of the canal (geometry, roughness) and of the downstream cross structure. {A} test canal with a weir or a gate at the downstream end is used to compare the new method with some of the others. {R}esults show that the proposed expression accurately reproduces the response time for various backwater and downstream boundary conditions.},
