Abstract: An open irrigation network is a physical infrastructure composed of canal reaches and numerous structures such as offtakes and cross-regulators, which conveys, regulates and distributes water for irrigation purposes. Each structure is meant to transform an input variable into an output one and the flexibility of the output with respect to input variations could be expressed by a structure sensitivity indicator. The sensitivity analysis approach, applied to irrigation systems, might be considered as an intermediary approach between steady and unsteady flow conditions for describing the flow behavior in irrigation canals. In this paper a preliminary analytical framework is developed to address the sensitivity of irrigation systems. The development of hydraulic sensitivity indicators at local and reach levels were presented. This approach could be used in canal operation assessment.
