The current research is focused on evaluating and designing a proposal for a stabilization system for riparian defense with gabions of the slope of the Botafogo Jetty - Tambopata River, Tambopata province, department - Madre de Dios, establishing a system of gabions, the mattress type gabion that counteracts soil erosion and the box type gabion that stabilizes the slope. As preliminary studies, an in situ inspection of the slope was carried out by performing a topographic survey that will provide the profile of the slope. To determine the physicalmechanical properties of the soil of the slope, three test pits were excavated along the study area located between km 3+600m to km 3+800m, from which the following tests were performed Characterization of the material (Moisture content, Granulometric Analysis by soil sieving, Liquid Limit, Plastic Limit and Plasticity Index), Soil Classification SUCS method in which it was determined an inorganic silt soil with clay of low plasticity (ML - CL) lacking gravel, the Light Dynamic Penetration test which provided the angle of internal friction of 27. 82° as a minimum value to finally obtain the bearing capacity of qa = 0.84 kg/cm2 required for the design. For the design of the proposal, a hydrological study of the area was also developed. This study consists of obtaining the maximum discharges based on the 24-hour maximum rainfall report recorded at the Puerto Maldonado, Quincemil and Tambopata stations, information provided by SENAMHI and by the hydrological study of the basin of the department of Puerto Maldonado. To determine the maximum flows, the basin was previously characterized by determining its geomorphological parameters with the help of the WMS (Watershed Modeling System) software; for a return period of 50 years, the flow was estimated at 1541.09 m3/s using the Creager method. For erosion control, the slope scour was calculated using the Levediev method, obtaining a scour depth of 4.10 m through data obtained from the hydraulic modeling performed in the HecRas software. With the data obtained from the soil mechanics, hydrological and hydraulic studies, a box gabion with a height of 1.00 m was designed to stabilize the slope and a mattress gabion with a height of 0.30 m was designed to control the slope that has the function of controlling the erosion produced by the river, each one filled with stone of specific weight 14.61 kN/m3 and with a total height of wall of 7.00 m whose function will be to mitigate the sliding and scour that is produced by the increase of the water of the Tambopata River according to the final design.
