This research applies the methodology of the "Manual for the evaluation risks caused by Natural Phenomena" of CENEPRED, allowed us to: analyze evaluation parameters and susceptibility (conditioning and triggering factors) of the flood hazard; analyze the vulnerability of elements exposed to the phenomenon based on fragility and resilience, determine and zone the risk levels of Bellavista Nanay sector, Punchana district. The Hierarchical Analysis Process (Saaty, 1990) was used, different parameters that intervene in the danger are prioritized, the triggering factors being the level of the river at a height of 117.17 m.a.s.l. or maximum daily rainfall of 99 mm (equivalent to percentile 50 of both variables), which affects more than 90% of population. It has been determined that 78% of the population is vulnerable "Economic and social vulnerability" and it was estimated that 74% of the population of the Bellavista Nanay sector in the district of Punchana are in the HIGH to VERY HIGH risk range. represents a population in extreme poverty and with little resilience in the face of a flood process. They are located on fluvial land, that is, the course of the Amazon River that is now covered by the Itaya River due to its displacement. With the AHP, it has been estimated that 9% of the population of Bellavista Nanay and its surroundings have high Resilience and are within the LOW risk level. Within the economic vulnerability, it can be seen that there is 10% population of Bellavista Nanay sector that has high Resilience, being located very close to the semi-dome (geologically favorable for construction), located in the highest part and with economic power that mitigates the impacts of any flooding.
