“…Horst (1983) and Bos (1988) reviewed the sensitivity of canals and related structures. More recent works on the sensitivity of irrigation structures are by Renault (1999Renault ( , 2000a, Renault and Hemakumara (1999) and Renault et al (2001). Renault and Hemakumara (1999) mentioned that the ability to identify the locations of the sensitive points or sensitive parts of the system is of special importance to managers.…”

“…Renault (2000b) also proposed an aggregation process for the computation of lumped sensitivity indicators at reach and canal level. Renault et al (2001) recommended that the sensitivity indicator should be determined for the full supply depth and the maximum discharge through the offtake. The available head through the structure is the most influential factor for sensitivity.…”

Monitoring and effective operation of control structures are of importance in a modern irrigation system. Previously developed sensitivity indicators can be useful tools for better management of irrigation systems. The influence of lateral canal water depth on the offtaking and ongoing discharges were simulated and evaluated using a simple model in the Doroodzan irrigation system in south-western Iran. Results confirmed the influence of water level changes in the lateral irrigation canal on offtake and cross-regulator discharge. Results obtained also led us to introduce and evaluate two other sensitivity indicators: offtake sensitivity to downstream water depth, and check sensitivity to tertiary canal water depth.Application of the sensitivity indicators in the Doroodzan irrigation system showed the usefulness of developed sensitivity indicators. The average sensitivity indicators varied from 1.10 to 0.44 (m À1 ) for offtakes and 0.58 to 0.03 (m À1 ) for cross-regulators.
