Study is directed to vertical drainage parameters and efficiency definition, water-salt balance regulation for river lower reaches. Climate is sharply continental. Relief is terraced. Area is 1327ha Ground water salinity is l-3g/l, sulfate type of salinity. Soil- desert and meadow-desert sandy loam, loam (light, medium and heavy), salinity type is chloride-sulfate. There are 8 vertical wells of depth 40-59m. In-farm canals with concrete lining and flumes with specific extent 24 m/ha. Plot is equipped by water metering devices. Vertical drainage regime has been developed providing optimal soil reclamation regime in conditions of alluvial valley with low thickness top deposits.

Key words
