MATHEMATICAL MODELING OF THE MOVEMENT OF SOLID PARTICLES IN CHANNELS AND OPEN BEDS

Rivers consist of a collection of several tributaries, and these tributaries are formed mainly in mountainous areas. The high speed of the water flow in the rivers, its movement over various rocks that are eroding as a result of a sudden change in natural temperature, causes these rocks to erode and move together. Their sizes are different, and they begin to move by sliding or rolling in the current. During this type of movement, the particles of friction are separated from their composition, and the solid pieces with a sharp appearance begin to turn into rocks with a smooth surface. Based on the results of experimental studies conducted by D.Mind and S.Shubert, it was determined that the speed of the air supplied to the aerodynamic pipe depends on the concentration of soil and nano particles sprinkled on the grids
