Abstract
Accurate water measurement and delivery are basic issues in irrigation networks management and performance. In this regard, baffle modules have been considered as appropriate means for delivering almost constant discharge within a specific range of upstream water variation. The structure is meant for low discharge delivery and could be employed in farm irrigation. However, the design criteria still requires further improvements. In this paper, the hydraulic sensitivity concept was used to provide two design methods for a 2 baffles module. The results of the first method presented a structure with -13.62% deviation of design discharge. While the second method resulted in a design criteria for baffle sluice module with only 2 baffles which its performance is similar to a 3 baffles one.
