“…Another field of research in irrigation puts this hydraulic aspect in the centre, to study ways how the hydraulic behaviour of the irrigation infrastructure can be improved (for example Clemmens and Schuurmans, 2004;Montazar et al, 2005;De Vries and Anwar, 2006;Van Overloop, 2006). However, these detailed discussions on mathematical solutions to understanding canal flow, modes of operational control and other subjects systematically leave out references to social reality.…”

The demand upon irrigated agriculture to modernize to improve productivity is increasing. This paper defines some of the key challenges the irrigation experts face in responding to this societal demand on irrigation, with a focus on water delivery. Histories of management and design in irrigation engineering still influence current perceptions of irrigation, although new ideas from research have influenced the ways irrigation management has developed in the last 30 years. Currently, modernization of irrigation is understood as transforming irrigation management to enable it to serve the demands of farmers. The position of irrigation experts changed from being the main person responsible for an entire production system to being a service-oriented manager. Taking into account farmer demand and responses to water deliveries is still a challenge for many agencies. The paper argues that, even though farmer interventions are not always appropriate, farmer interventions are to be taken as standard in irrigation. Engineers should ensure that systems deliver what is asked for, through selecting physical components within a clearly defined operational strategy. Such a service-oriented approach demands irrigation experts with high technical qualifications in hydraulics and hydrology. Copyright RÉ SUMÉ La demande de modernisation de l'agriculture irriguée pour améliorer la productivité augmente. Cet article présente quelques-uns des principaux défis auxquels les experts en irrigation sont confrontés pour répondre à la demande de la société, en mettant l'accent sur la distribution de l'eau. L'histoire de l'ingénierie de l'irrigation a encore une influence sur la conception et la gestion de l'irrigation, bien que, depuis trente ans, de nouvelles idées issues de la recherche aient permis la mise au point des nouvelles pratiques de gestion. Désormais la modernisation de l'irrigation est comprise comme la transformation de la gestion de l'irrigation pour lui permettre de répondre à la demande des agriculteurs. L'expert n'est plus en position de principal responsable de l'ensemble du système mais de gestionnaire axée sur le service. Prendre en compte la demande des agriculteurs et leurs réponses à la fourniture d'eau est toujours un défi pour de nombreux organismes. L'article fait valoir que, même si les interventions de l'agriculteur ne sont pas toujours appropriées, ce sont elles qui doivent être prises comme norme en irrigation. Les ingénieurs doivent veiller à ce que les systèmes délivrent ce qui est demandé, en choisissant les composants physiques dans une stratégie opérationnelle clairement définie. Cette approche axée sur le service demande des experts hautement qualifiés en hydraulique et en hydrologie.

“…According to [4], a crucial development in water management will occur in the next decades due to using new techniques, like optimisation and modelling, which scientists are advancing. This modern management is highly needed in most developing countries, which have little resources to allocate to develop new techniques for irrigation management [5].…”

Open channels are very important to deliver water from main sources to laterals especially for developing countries. Production is subjective by the way that the water is scheduled, and this scheduling is subject to several irrigation constraints. In open channel projects, for instance, maximum discharge of the laterals and main channels, depending on the size of their dimensions and the water requirements for fields. The current paper shows how efficient water scheduling, regarding the delivering water from the main channel to laterals in consequent time slots, can be done by utilizing a genetic algorithm optimisation technique. This research is intended to be applied for scheduling the Shattulhilla River in Babylon City and has broad applications for open channel projects in Iraq. The obtained results clarify how the genetic algorithm optimisation modelling is a sophisticated tool which operators of irrigation projects could now utilize to timetable open channels of irrigation systems.

“…Often these problems involve making the most efficient use of available resources including money, time, machinery, staff, inventory, and land and water. These problems have been solved by using different optimization techniques from the researchers from worldwide (Anwar and Clarke, 2001;Ayvaz and Karahan, 2008;Azaiez et al, 2005;Bar et al, 2009;Bardossy et al, 1990;Chiadamrong and Kawtummachai, 2008;de Vries and Anwar, 2006;Easa and Hossain, 2008;Hsu and Wei, 2007;Hsu et al, 2008;Hugo, 2004;Joubert et al, 2007;Kale et al, 2008;Karmakar and Mujumdar, 2006;Majone et al, 2010;Mattilal and Duley, 1998;Pathumnakul et al, 2011;Ravirala and Grivas, 1995;Sadeghpour et al, 2006;Salazar et al, 2005;Stray et al, 2012;Wei and Hsu, 2009;Zhang and Huang, 2011).…”
