THE FILTRATION PROPERTIES FEATURES OF TECHNOGENIC DEPOSITS
04.00.00 Geological-mineralogical sciences
DescriptionThe studies of synthetic sand deposits formed after working dredges deposits in river valleys, have established significant heterogeneity of filtration properties of elementary layers of sand of different grain size distribution. The features of the structure of the array of man-made structures provide a large capacity of absorption of suspended clay particles and the conditions for water purification by adsorption

DescriptionHydrogeological conditions and problems of regional hydrogeological works of the territory of the Perm Ural and Priurals are characterized. Possibility of providing the population is shown by fresh underground waters. The methodology of mapping of the water-bearing zones on a complex of the methods including the lineament-geodynamic analysis with allocation of geodynamic active zones on the basis of remote researches and geoinformation technologies is considered

EXPERIMENTAL RESEARCH AND MODELING OF PACLOBUTRAZOL MIGRATION IN SOIL
04.00.00 Geological-mineralogical sciences
DescriptionIn this study, we have investigated the migration of paclobutrazol in the sod-podzolics soils. The migration of pesticide was restricted with 5 cm in the field study. Paclobutrazol was found in 11 days after application in the lysimeter’s water samples, though the pesticide is moderately mobile. The lysimeter study showed that the risk of ground water contamination would exist if application of paclobutrazol was on the sod-podzolics medium loamy soils. The modeling by PEARL 4.4.4 and MACRO 5.2 simulated the migration of paclobutrazol until 18 cm in the soil. MACRO was able to predict the leaching of pesticide. The simulated paclobutrazol losses by leaching were consistently lower than the observed
