Subjects of Research: pressurized water systems of transportation of river drift with blasters Purpose of the Work: - Conducting research on the transportation of river drift in pressurized systems with negative slope and formulating methods of hydraulic calculations for applied issues; - Conducting research on the nature of formation of cross section canals in watercourses considering kinematics of turbulent flows Methods of Research: Upon the couse of preparing this work basic provisions of the theory of movement of liquid on pipelines and the theory of the expiration of liquid through openings and nozzles were used. On the basis of these theories and carried-out experimental studies formulas for determination of dependence on Reynolds's number is offered. The experimental studies were conducted in accordance with the standard methods of laboratory research. Results obtained and their novelty: - The impact of energy in the transportation of river drift via pipes of negative slope has been calculated; - Silt carrying capacity of pipes with opposite slope has been established; - Hydraulic parameters of Jet Injector devised to clean water bodies from silt have been established; ( Patent No FAP 004900); - Methods of hydraulic calculation of silt movement in pressurized pipes of negative slope have been formulated; Practical Value: - Results of research are furnished to the level that would allow their direct application in the estimation of carrying capacity of hydro-transport; Results of the research can also be used to work out power saving technologies in the area of two-phase flows via pipelines taking into account the volume concentration of phases, the sizes of particles, etc.; - Use of the received results at designing and building of hydro-transport systems considerably improves transportation ability and economic efficiency; Degree of Embed and Economic Effectivity: The results of the present research work were used at Management of Unitary Enterprise "Suvsoz" for improvement of operations in sediment bowl and water abstraction facilities and in educational processes as manuals for professional training of students in the respective directions. Economic efficiency is attained as a result of power saving upon removal of river deposits. Field of Applications: Project Institutes, water basins, sediment bowls, educational purposes.
