Introduction [2] Porosity, defined as the ratio of pore volume to total volume, is one of the key properties of a fluvial sand-gravel mixture and an important parameter in morphological, ecological, geological, and geotechnical applications. Morphologically, the porosity exerts a strong influence on the rate of bed level changes that occur in water systems.
