The main objective of this thesis was the characterization of the evolution of suspended sediment and bedload of the Tumbes river in the Puyango-Tumbes basin, depending on the discharge during large floods in the El Niño event. To achieve the objective we included the use of an Accoustic Doppler Current Pro filer (ADCP), to monitoring the discharge and the solid flow in suspension and rivers bed. The database used for this research was provided by the Institute Geofísico del Perú (IGP). This database was generated during the project "Monitoreo, caracterización e identificación de las principales fuentes de erosión y sedimentos durante crecidas o eventos extremos El Niño en las cuencas binacionales Puyango-Tumbes y Zarumilla", funded by INNOVATE PERU. Total sediment transport (Qst) during the sampling campaign for the Puyango-Tumbes basin at El Tigre station was 2.79 million tons, of which 99 percent is transported in suspension (2.78 million tons ) and 1 percent for bed load (0.015 million tons ). It was found that the transport of suspended sediment is limited by the supply of sediment (washload) because the greater occurs at the beginning of the wet season, due to the high available material, and decreasing until the end the wet season. About the bedload transport, it was determined that methodology presented by Rennie et al. (2002) is the one that best approximates the observed data of bed load, obtaining a correlation R=0.43 between the bed load transport and the flow rate. Erosion was detected and documented during the wet season by ADCP measurements in the Tumbes river, being the most complete at national level. With this, it was possible to determined that the hydrometric section undergoes in many changes during the wet season. these changes can a affect the precision of the flow rate calibration curve in the station El Tigre.
