Análisis de la dinámica fluvial del río amazonas en el municipio de leticia y su incidencia en el ordenamiento territorial

Abstract

This document presents the development of the thesis entitled “Analysis of the Fluvial Dynamics of the Amazon River in the Municipality of Leticia and Its Influence on Territorial Planning”, prepared as a requirement to obtain the degree of Master in Integrated Watershed Management. The main objective of this research is to analyze the fluvial dynamics of the Amazon River and its relationship with territorial planning processes, with special emphasis on flood susceptibility in the urban area of the municipality of Leticia. To carry out the study, a multitemporal analysis of fluvial dynamics was conducted through the photointerpretation of satellite images and historical cartography corresponding to the last 55 years. Based on the digitization and georeferencing of this information, changes in channel morphology, erosion and sedimentation processes, as well as the formation and transformation of fluvial islands were identified. The results reveal the presence of a meandering channel with an extensive floodplain, characterized by pronounced bends and geomorphological processes that influence territorial dynamics and contribute to the development of flood-prone areas. As a final result, a multi-temporal cartographic product was developed that integrates river dynamics, geomorphological interpretation, and their relationship to land-use planning. This product allows for the identification of areas susceptible to flooding and constitutes a technical input of an academic nature to support land-use planning and decision-making in the municipality of Leticia.
