Soil erosion is the intricate process of detaching and transporting soil materials from their original location, driven by various erosive forces. The erodibility of soils refers to their inherent vulnerability to erosion. The Hole Erosion Test (HET) is a critical method for assessing the stability of river banks, particularly in the context of ongoing environmental changes and infrastructure development. This test involves the controlled introduction of hydraulic forces and sediment dynamics to simulate erosive conditions along riverbanks. The HET has been developed to study the erosion characteristics of soil. The erosion rate index, which measures the rate of erosion, and the critical shear stress, which denotes the lowest shear stress at the beginning of erosion, both characterize the features of erosion. The HET results aid in the sustainable management of riverine environments, mitigating the adverse impacts of erosion, and ensuring the long-term stability of riverbanks in the face of evolving environmental challenges.
