Annotation: On the example of improving the functioning of melioration networks of Karaulbazar district of Bukhara region-Improving the melioration of irrigated lands in the area and increasing crop yields, increasing the productivity of existing melioration networks. New innovative ideas will be developed in this area. In practice, mechanisms for their table are provided. According to long-term observations, the average annual groundwater level in the irrigated areas of the Karaulbazar district is 3.08 m-3.17 m. The hydro-chemical regime of groundwater is also applied to irrigated areas when analyzing the location of the groundwater table in the characteristic period of location, after vegetation 3.17 m before April 1, 2.98 m on July 1 and 3.08 m after October 1. That is continuously related to the amount and mineral composition of the wastewater supplied and its location. The chemical composition of groundwater is much more complex and consists of concentrations of large amounts of harmful mineral salts. The advantages of closed drainages are also described.

Keywords: irrigation sources, underground water, temperature; water consumption regime, water balance, precipitation, evaporation, closed drainage, drainage modules.
