“…When designing collectors, special attention should be paid to the design work based on the above requirements. However, in the given normative documents, for the values of the flow depth from 0.5 m to 5 m for the determination of the velocity of the self-washing, there are problems in the design of collectors on the basis of the unwashed speed [16,17,18]. Because in most cases in the design of collectors, the flow depth is designed at values less than 0.5 m. Based on the results of field studies and analysis of samples taken in the laboratory, non-flushing velocity values were determined in accordance with the flow depth in the design of the collectors (Figure 7).…”

The article evaluates the hydraulic processes in the collectors which constructed in irrigated fields. Illuminated the washing processes under the influence of the flow velocity in the collector bed. In order to study the washing processes in the collector basin, are covered the results of research conducted in the self-washing collector in natural field conditions. Collector 2-K-4 in Khavas district of Syrdarya region was selected as the object of research. Given cases of changes in the project parameters as a result of washing processes in the core of the collector. Were selected 5 sections in the collector and hydraulic parameters were studied. was evaluated the effect of hydraulic processes on the collector core. The studied sections show cases of change of design parameters under the influence of hydraulic processes. Soil samples were taken from the reservoir and the mechanical composition was determined under laboratory conditions. Based on the laboratory and natural field conditions results, a special graph was developed for the design of collectors on the basis of non-washable speed.

“…MODFLOW (Flow Modeling) was developed in the 1970s using the American FARTRON programming language and has created generations that have evolved to the present day. The MODFLOW modeling and forecasting system is developed by several companies and is not interconnected [9,10,11,12]. In our study, Visual Modflow Flex 2015 was used.…”

The study was conducted as part of a project to develop an automation system for monitoring groundwater in the city of Urgench. The possibilities of modeling and forecasting modeling MODFLOW in groundwater were studied. According to the results, regularities of the level and behavior of groundwater in the city of Urgench were revealed. According to the survey, the direction of movement of groundwater in the city of Urgench shifts in a northwesterly direction to a slope of 0.0008. According to the geophilized model, its high-traffic zone is located at a depth of 10-15 m, from 4-5 m per second.

This article provides an analysis and recommendations of the factors that lead to the loss of water as a result of filtration in uncoated canals, rising groundwater levels, deterioration of land reclamation, reduction of canal efficiency coefficient. According to the project data, the part of the Greater Fergana canal from PK-930 to PK-1500 + 10 was built in the type of semi-excavated and natural canal. From PK-930 to PK-1040, the ground level is almost equal to the bottom water level, and the volume of soil discharged in this part of the canal is greater than in other parts. The canal is in the form of a trapezoid and has now changed its shape slightly as a result of a small amount of sedimentation and erosion. In uncoated canals and irrigation systems, there are a number of connections to perform the basic filtration calculation. These bonds are obtained according to Darcy’s law, filtration for homogeneous and isotropic soils. Using the available data, it is possible to determine the depression curve in canals and irrigation systems for all cases, the points that form its curvature, and the filtration rate that occurs in it. It consists of determining the filtration rate (q) of the system at a length of 1 pogm and the filtration coefficient (k) of the soil.
