The objective of the investigation is to delimit the flood level of the city of Punchana through photogrammetric survey using drones or UAV, to delimit an intangible zone called Faja Marginal, Law 29338. A Phantom 4.0 pro drone was used for its maneuverability in small spaces and small size, with RGB sensor. It is designed to carry out scheduled routes with automatic takeoff and landing, controlled by radio frequency in real time and a 13 Megapixel camera. In the flight plan, flights were carried out at an altitude of 80 meters and an overlap of 60%. Complemented with the SEHINAV geodetic control point of order “0”. The Horizontal Reference Datum WGS 84 (World Geodetic System 1984) with UTM projection (Universal Transverse Mercator) zone 18S and the vertical Reference Model GEOIDAL EGM-96 was used. With the images obtained and the control point, the orientation of the images is carried out, the stereoscopic pairs are compared and a digital elevation model of the city and an orthomosaic are obtained. The results indicate that the elevation established by SENAMHI 117.00 masl (84.85 m in the geoidal model) delimits the sector with flood risk from very low to zero with the sector with high flood risk, known as the beginning of the Marginal Belt or Line Ordinary Crescent (LCO). One of the causes of flooding over Punchana district is the proliferation of about 200 human settlements that are within the area vulnerable to this process, which when the Nanay and Itaya rivers enter the peak season (February to May) addresses to families located on said territories. The area of the city of Punchana with low flood risk is 329.84 which represents 7.5% of the entire city of Iquitos, that is, a large urban part of the city of Punchana is located within the marginal strip, which makes it a social problem. The study serves as a technical basis to determine the areas of special treatment for the Authorities belonging to the National System for Risk and Disaster Management - SINAGERD
