In the course of this research, the method of determining sediment flow in stationary streams was considered. Taking into account the bottom and suspended state of the sediment, the method of calculating sediments with an unsteady flow related to the calculation of the transport of the sediment itself was analyzed.

Based on the Ackers-White dependencies for determining sediment flow in stationary flows, a method for calculating sediment with an unsteady flow is proposed, taking into account the division of sediment into bottom and suspended, which relates to the calculation of sediment transport itself.
