Water Erosion Hydrodinamical Impact on the Soil at Iirigation Processes

The researching and examinations of the irrigation processes, as well the processes causing erosion of the soil furrow beds and the alteration of their state in practice is done based on the flow velocities averaged-out in time. Through the hydraulic researches, it is known however that the real, actual velocities are pulsation velocities into the cross section of the water flow, which are irregularly variable in time and different from the averaged flow velocities. In view of this, in the present work the relations were realized on the basis of the pulsation velocities of the water flows. On this basis, a water erosion approach and method is offered for prediction of the erosive state and stability of the furrows for irrigation.
