Ecological Systems and Devices Annotation << Back Investigation of features of aero and hydro-dynamic currents in the narrow channels in view of compound relief of bottom Khvedelidze Z.V., Davitashvili T.P., Samkharadze I.N. In present report the peculiarities of the hydro-dynamical flows in a narrow canals with small slope bottom, at low velocities of the stream, have been studied. It has been shown that the velocity and power of the currents are inversely proportional to the square of the parameter characterized the special features of the canal’s bottom . In the existing vortex stream the pressure decreases inversely proportional to the distance from the center. The present theory gives possibility to determine the velocity of flows and spreading of pollutants in the rivers or intermountain plains. Key words: pollution, environment, modeling.
