Abstract: Rivers are constantly changing their behavior and morphology, which may result in alterations to the river channel course and the development of the flood plain due to erosion processes and sediment transport. Preventing soil loss and maintaining riverbank integrity under the flow effect requires implementing an erosion control system. The forces balance for bank stability depends on geometry, the properties of bank materials, and the hydraulics of flow in the channel. This study analyses the design of mattresses as an erosion control system. The design was improved by optimizing the connection between the base, panel, and lid, including cell fit through diaphragm spacing. Significant improvements can be attributed to the introduction of vertical connections, enabling fast installation, especially on steep slopes. The new mattress features greater allowable shear stresses with a lower thickness, implying the reduction of stone fill volume. A better erosion control system will be of great importance for river engineering regarding soil and water management and even environmental protection.
