Modelación Hidrodinámica del Comportamiento Espacio -Temporal de la Escorrentía Superficial en las Áreas Adyacentes a la Entrada del Túnel de Pamplona.

Abstract

The main purpose of this degree work is to analyze the spatial behavior temporary surface runoff in the area between the entrance of the double tunnel Pamplona–Cúcuta road and the Simón Bolívar block of the University of Pamplona. The context geographic and urban development of the area, characterized by increasing soil waterproofing and modifications to the infrastructure have increased the risk of flooding, affecting directly to the university community. Based on this problem, a model was developed hydrodynamic that allows identifying vulnerable areas in the face of extreme precipitation events. The methodology was structured in three phases: first, the Digital Model of the Terrain (MDT) using drone flights and correction with RTK technology; then, it was implemented the hydrological model in HEC-HMS; finally, the hydrodynamic model was applied in IBER to simulate different flow scenarios and generate depth and velocity maps. The results showed that, for the different return periods (10, 50 and 100 years), the area The university parking lot presents a low risk of flooding, while the entrance to the campus concentrates higher values of depth and speed, which requires special attention due to the convergence of the flow of several sub-basins. However, in general terms, the system The existing drainage system shows an acceptable response, although it requires additional measures. mitigation. In conclusion, this study allowed us to identify critical points of accumulation and speed of the flow, and provides a useful technical tool for urban planning, risk management and institutional decision-making. Its results can be used by local entities and regional as a basis for prevention and adaptation strategies to climate change
