The article highlights the unique role of irrigation canals in the supply of water in the required amount, depending on crop demand and the rational use of it. The study of the prevention of filtration in irrigation networks and the study of the existing malfunctions in the operation of irrigation networks, the sequence of works on the repair of irrigation networks were analyzed, and the priority of repair work was determined. The current state of the Khumbuz canal in Khiva, Khorezm region of the Republic of Uzbekistan was studied. Information was obtained and analyzed on compliance with design specifications during construction and the presence of protection zones in the canal design. Analytical indicators have been developed to extend the service life of the Khumbuz canal to ensure its normal operation and supply the required amount of water to crops. In the implementation of water supply to agricultural crops, priority is given to the repair and construction of hydraulic structures, including the Khumbuz canal. In addition, all the work to be done was planned based on the priority of the work. It has been found that the amount of water required to irrigate crops can be achieved uniformly along the length of the canal, at the top, middle, and bottom of the canal, by ensuring that the irrigation networks operate at the required level. Specific scientific recommendations have been given for the normal operation of the Khumbuz canal. Repairing the canal has been shown to increase water use by 20 percent and increase crop yields by 15 percent by ensuring that crops receive the required amount of water on time. The service area of the Khumbuz canal is 1.460 hectares. The length of the canal to be repaired is 6 km. of which 2,568 km of new concrete. The maximum water flow of the canal is 2.5 m3/sec, and the normal water flow is 2.0 m3/sec. The efficiency of the channel (canal) is 0.93. The article provides information on how to achieve efficient use of irrigation water by repairing hydraulic structures at the required level and the construction of new ones.

Flooding has a wide range of impacts on societies and natural environments. In this sense, the city of Fez suffers from these problems reflected by the overflow of Oued El Jawaher during the rainy periods. This situation led the authors to compare between the current situation and the situation developed by the thresholds of Oued El Jawaher. HEC-RAS hydraulic model consists of 31 cross-sections, which will be used in the course of this study. The simulations will concern the current state and the developed state for flows of different frequencies. The result of the simulations confirms that the capacity of the proposed hydraulic structures is insufficient to transit and should be considered. To conclude, the development of the channel by thresholds, which serves for the creation of water plan, magnifies the risk of an overflow of the banks of the canal by the water line along with the longitudinal profile.
