06.00.00 Agricultural sciences
DescriptionA comparison of quantitative and qualitative performance of the selected clones of breeding of A.S. Yablokov and S.N. Bagaev has been made. At the same forest conditions, the clones are much higher than regular at reserves, the absolute completeness, the average heights and diameters of trees. Gigantic forms of P. tremula L. are resistant to infectious diseases, and at the fifth grade are characterized by good sanitary condition. We have also shown the economic feasibility of using of fast-growing clones in the genetic reserve for the organization of giant aspen of P. tremula L. plantation

SMALL-SCALE MODELING OF DYNAMIC FACILITIES FOR PROTECTION OF HYDROSYSTEM TAILRACES
DescriptionTo study the formation of plunge basin in the Cheboksary hydroplant, we used a scale model of the spillway dam and all structures in the tailrace, installed in the slot flume. When we passed the flow corresponding to the diversion flow of the hydroplant with a glance to the modeling scale, it was found that the plunge basin was formed behind the end fixing of the spillway apron. To research the dynamic facilities of hydrosystem tailrace protection against erosion, we used a small glass flume with a model of the roundcrested weir. For the experiment, the water-surface elevations were built in the flume without the weir, and the uniform motion area was established. In MathCAD software environment, the curve of the flow of measuring rectangular weir of the flume was created. Because of measurements, the curve of water surface by the flow motion through the round-crested weir was made. As the main criterion for modeling, the criterion of Froude was selected. Scale of modeling of flow parameters was determined. For testing, models of hydrodynamic profile and sail structure with streamforming sluice valves were built. The process of sand washout from the flume bottom and formation of the bottom ridges when installing the profile was photographed. Impact of the profile on the flow and its relation with the formation of the bottom topography were studied. Full-scale values of geometric parameters of the bottom ridges and their movement velocity were established as well
