In the process of sediment exchange from one region of the water column to another, morphological development occurs, as does the transmission of varying sediment concentrations and flow momentum along the stream. Herein, a one-dimensional hydro-morphodynamic model is proposed for simulating water flow over a rolling bed of non-cohesive materials to understand better how water flows. Flow hydrodynamics, sediment movement, and bed growth are all considered in this simulation. The governing equations were solved using first-order accurate Harten Lax-van Leer solvers, and the fluxes at cell sides were determined using a finite volume technique based on a structured rectangular mesh. Adding geometry and bed topography to the equations in both the x and y axes may be used to convert a onedimensional model to a two-dimensional model, which is a common approach to transforming one-dimensional models into two-dimensional models. Experimental measurements are also utilized to test and assess the integrated model.
