Geoportal para el análisis fisiográfico e hidrológico de cuencas en Colombia

Abstract

This undergraduate thesis proposes the design and implementation of an interactive web geoportal for physiographic and hydrological analysis of watersheds in Colombia. The tool integrates open-source technologies such as Leaflet.js for cartographic visualization, JavaScript for geospatial data processing, and potentially Google Earth Engine for cloud-based analysis, allowing non-specialized users to access processed hydrological information quickly, reliably, and at no cost. The main objective is to design and set up an interactive online system offering modules of watershed delineation, isohyet generation based on georeferenced meteorological stations, and modeling through TIN (Triangulated Irregular Network). These components will make it possible to carry out more accurate analyses of rainfall variability and physiographic characteristics of each watershed, thus serving as a valuable tool to back up decision-making processes in hydrological studies, water resource management, and infrastructure planning. The development methodology is structured in five phases: collection and processing of geospatial data from official sources, system architecture design based on modern web technologies, iterative development of functional modules, results validation through comparison with official studies, and technical documentation to ensure project sustainability. Expected outcomes include a fully functional web platform, publicly accessible and compatible with multiple devices, a validated automatic calculation system for hydrological parameters, isohyet generation tools using spatial interpolation (IDW), and complete technical documentation. The project's impact is projected across academic, professional, social, and environmental dimensions, strengthening research capabilities, democratizing access to hydrological information, supporting integrated water resource management.
