The main causes of river erosion include hydraulic action, where the force of flowing water dislodges materials from the riverbed and banks [2][12]. Abrasion occurs when sediment carried by the water scrapes against the riverbanks, further wearing them down [5][12]. Attrition involves rocks and sediment colliding with each other, resulting in smaller and smoother particles [8] [12]. Lastly, solution refers to the chemical dissolution of soluble materials like limestone in the water [6][12].
