Investigation of the interaction of hydraulic parameters of the channel in the filtration process

One of the most important and complex issues in the design of soil drainage channels is the issue of correct accounting of the filtration process. It is necessary to take into account hydraulic parameters and soil composition of existing channels in order to reduce filtration flow rate in ditches with uncoated soil. The article shows how to choose its theoretical basis for reducing the filtration flow rate correctly. Hydraulically convenient design is one of the current problems in the design of canals. This can be achieved by reducing the wet perimeter of the channel to reduce the filtration process in the channel. The article recommends that measures to reduce the filtration process be implemented during the construction or reconstruction of canals, without dismantling and rehabilitating existing canals. Field research was conducted on the North Fergana main canal. In order to study the filtration processes, measurement works were carried out on the PK 396+00, PK 497+01, PK 688+7, PK 692+6, PK 694+6, PK 697+00 pickets crossing the 2-section of the channel in the city of Namangan. In addition, the article developed recommendations on the methods and procedures for the application of bentonite clay from the Lagon betonet clay deposit of the Fergana region to the bottom of the channel in order to reduce the filtration process that occurs in the canal area. According to the results of the study, in the range from PK 411 + 00 to PK 426 + 74, filtration consumption was higher than other pickets

BALANCES OF SOIL WATERS OF COTTON ROOTABLE LAYER IN EXPERIMENTAL PRODUCTION SECTIONS

Regulation of the soil water balance item is the basis for creating optimal parameters for the reclamation regime ensuring a high crop yield. The values of the water balance item are determined using various formulas recommended by various researchers. Each formula, before applying, must be clarified for specific climatic conditions. With close occurrence of groundwater to the surface of the earth, euotranspiration increases. The main reason for the increase in euotranspiration is an increase in the recharge of the active soil layer by groundwater
