Citarum River is a river that passes through the village of Atirompe, Majalaya subdistrict. The condition of the Atirompe village area, which is located on a bend in the river, causes the Citarum river bank to scour, resulting in landslides on the river bank. When the condition of the river reaches bankfull capacity, velocity of the river flow will increase and cause degradation of the river bank. As a result, people's houses located around the riverbanks will continue to be threatened and cause losses for the residents of Atirompe village. Planning for riverbank protection structure needs to be carried out in order to prevent the occurrence of landslides on the Citarum River banks, especially in the Atirompe area. The hydrological analysis was carried out using 4 rain stations and observation discharge data, which are analyzed using the Gumbel method. The modeling of riverbank scour is carried out using the HEC – RAS 6.2 software and the results of riverbank scour are compared with the Ripley Equation. Based on the results of scour modeling, locations and segments of the river that are experiencing degradation are determined, and it is necessary to plan several alternatives of river bank protection structures, such as sheet piles, gabions, and river stone pairs. From each planning of riverbank protection structures, stability and development costs will be a factor in choosing the solution to the problem of riverbank scouring
