 Rational use of water resources in agriculture requires improvements in the efficiency of irrigation. Many irrigation systems, particularly in Mediterranean regions, have been enhanced by replacing open channel conveyance systems with pressurised pipelines. This allows providing water on-demand. Increased demand of water for civil and industrial uses and a progressive reduction of available water resources compel a more efficient use of irrigation water. To achieve this goal irrigation managers need to understand and to monitor the processes, which determine the operation of an irrigation system. Tools such as agrohydrological simulation models and remote sensing techniques can be used for this purpose. These techniques have reached a sufficient degree of reliability to be transferred to practical applications. Guido D’Urso has developed a procedure integrating the agrohydrological aspects of irrigation with hydraulic and management aspects. The procedure named SIMODIS (SImulation and Management of On-Demand Irrigation Systems) can be used in support of irrigation decision making. A case study on the application of SIMODIS was carried out in an irrigation district of 3000 ha in southern Italy.
