Paisaje hídrico resiliente: Estrategias de Diseño Urbano Sensible al Agua con proyección al cambio climático para la planificación de la cuenca baja del Río Tunjuelo.

Abstract

The urban water landscape is constantly under threat from the pressure of anthropocentric actions and the effects of climate change, causing negative impacts on the environment and even the disappearance of ecosystems. In order to mitigate this risk, the Tunjuelo River in the city of Bogotá has been the scene of various proposals and technical interventions that have incorporated limited prospective planning alternatives based on sustainability, risk management, and resilience criteria.

Due to the lack of projections or simulations, actions are taken that are not very functional in mitigating risks and maintaining a sustainable landscape. Therefore, this work aimed to establish strategies for water-sensitive urban management and design under proper edge management with a focus on climate change projection for possible inclusion in the city's Master Plan (POT), with the aim of improving the urban-environmental conditions of the lower basin of the Tunjuelo River. To achieve this, it was essential to characterize the analysis unit to understand the current conditions of the water source and its surroundings. Simulations were also conducted under flood variables to highlight the future behavior of the basin and, thus, provide recommendations for design considering both landscaping and functionality.

The applied methodology for the research involved an analysis of three specific transects of the lower basin of the Tunjuelo River with different morphological and urban characteristics. This allowed the representation of prospective scenarios, constructing models that revealed the behavior of the Tunjuelo River facing phenomena such as floods. The results obtained from the projections indicate that, given the current state of the urban basin and considering the increased precipitation and its speed, the water source is susceptible to the risk of overflowing, which not only affects the ecosystem but also the overall environment.

These results led to the formulation of a matrix of recommendations and models for early stages of design in urban water edges, emphasizing the importance of generating prospective scenarios to ensure an appropriate relationship between water sources and the urban environment. This guides architects, urban planners, and decision-makers in the formulation and execution of territorial planning to achieve sustainable and resilient landscapes.
