Abstract

ORTEGA-GAUCIN, David et al. Model for the optimization of resources for an irrigation district. Terra Latinoam [online]. 2009, vol.27, n.3, pp.219-226. ISSN 2395-8030.

Using linear programming techniques, a model for optimizing water resources was developed for the Irrigation District 005, located in Delicias, Chihuahua, Mexico. The proposed model allowed estimation of the irrigation area and optimal cropping pattern needed to increase net benefits for growers. Four possible scenarios were analyzed, considering the availability of key volumes in water supply sources, as well as two conduction efficiencies for the network of irrigation channels. The results indicated that the area cultivated in the Irrigation District was 79 459 ha. The area estimated by the model was 9643 ha less than the area currently irrigation. It is thus concluded that it would be recommendable to establish strategies for withdrawing the excess area from the Irrigation District or for reducing water concessions in order to achieve sustainability of the modules.
