RESEARCH OF SYSTEM OF JOINT REMOVAL OF SUPERFICIAL AND DRAINAGE WATERS FROM CITY TERRITORIES
DescriptionIn the article substantive provisions of the offered system of drainage storm waters removal are reflected. Dependence for calculation of residual values of the weighed particles in a stream from speed and time of movement of drains is established and optimum parameters of the tank-sediment bowl are defined. The technique of forecasting of quality of water in drainage storm system with due regard for diluting both storm and thawed snow drainage waters and processes of physical and chemical and biochemical self-cleaning is developed. Eco-economic efficiency of system is defined

EFFECT OF DRIP IRRIGATION ON SOIL SALINIZATION
06.00.00 Agricultural sciences
DescriptionThe article presents the results of researching into the effect of drip irrigation on build-up of soil salinity using water with high salt content and the dynamics of changes during winter period under atmospheric precipitation. It was established that at the end of irrigation season zones with high salt content formed on the soil surface under drip irrigation using sodium sulfate water, among these salts gypsum was presented. In spring time the increasing of sodium sulfate content was found that indicates the exchange reaction with soil exchange complex passed as well as the insufficient salt leaching occurred during the winter period. In spring time the upper soil layer characterized with alkaline type of soil salinization
