01.00.00 Physical-mathematical sciences
DescriptionDiffusion-convection equation that has been received from Saint-Venant differential equation system describing nonstationary fluid motion in a river canal is investigated. Analytical method is considered for the solution of equation with the fixed factors and finite-difference method is considered for the solution of equation system with the float factors. The results of test calculations executed for a reaches of the river Kuban are presented

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
