ZONING OF THE SOUTHERN RUSSIA TERRITORY ACCORDING TO HEAT AND MOISTURE SUPPLY FOR THE COTTON INTRODUCTION
- Land reclamation, water manadgement and agrophysics
Hydraulic means for controlling the level of downstream water at the hydraulic facilities are presented. The proposed constructions do not require additional power supply and the reconstruction of existing hydraulic structures. The constructions are characterized by simplicity and reliability in operation. They can be used at intraeconomic irrigation network with service capacity up to 1.5 m³/second for hydraulic facilities with tube diameter from 0.3 to 0.6 m and hydraulic drop at the facility not less than 0.2 m. The accuracy of the given level controlling was from ± 2cm to ± 4 cm.
