An effective and sustainable solution to address the problem of riverbank erosion, protect the environment, and offer economic and operational benefits. In addition, this research also contributes to the development of science and technology in civil engineering and water resources management. The study's objectives were to formulate stability coefficients of rock-pile kribs and analyze how changes in each variable affect the overall stability of the kribs. The research methodology conducted was a literature review, theoretical analysis, and physical modeling. The expected results are to find the relationship between river flow parameters and the stability coefficient of rock piles, to see the flow pattern that affects the stability of rock piles in the krib, and to find the influence of the position of the krib on the stability of the rock pile krib. It is estimated that the weight of the rock pile krib building face layer (W) is influenced by the flow velocity (V), the specific gravity of the rock (S), the stability coefficient (Ks), the slope of the structure (Cot), and the water depth (h). The use of natural materials in river management is effective in controlling erosion, directing water flow, creating new habitats, and protecting riparian infrastructure. Further research on the stability of rock-pile-type river Kribs experimentally under various river conditions, as well as innovations in rock design and materials, is relevant and important at this time.
