| description | Accurate and correct hydraulic calculations are important in the projection of open drainage systems. Because of the hydraulic calculations, it is possible to determine the parameters while constructing it. For calculating the hydraulic, it is necessary to determine the amount of filtration water from the cultivated fields. Crops and irrigation norms differ in the irrigated areas. Of these, rice is the most demanded of water. This article describes how to use GIS to determine the drainage water flow discharge into the open drainage system in the area under cultivation. The research object was the Central Mirzachul open drainage system which was constructed on irrigated land in the south of the Syrdarya region, located in the Mirzachul area. Sentinel 2 satellite imagery was used to identify rice fields in the study area. Downloaded satellite images were analysed using the ArcMap application of ArcGIS, and several steps were taken to create and map a study area. Based on the results of the analysis, the surface and size of the rice fields are determined. Hydraulic calculations were provided based on the determined data. As a result of hydraulic calculations, it was determined that the collector drainage system with the length of 1200 m drops 4.1 m3/s water from the rice fields. |
