Riverine Bridges: A Hydrological Vulnerability Appraisal



Recent studies on the recurrence and severity of meteorological phenomena suggest that these indicators have increased considerably due to several factors, including climate change. Important infrastructure such as riverine bridges have demonstrated a lack of resilience to the consequences of these phenomena. It is important, then, to analyze their vulnerability for future interventions and thus mitigate the risk to users. Through the case study of the Bajo Grau Bridge in Peru, which crosses the Chili River, a methodology is proposed to identify the most relevant parameters for diagnosing the condition of riverine bridges in order to determine their hydrological vulnerability.

A fundamental aspect of achieving the research objective is data collection and analysis. Since the analysis is interdisciplinary, it is important to manage information from all areas in an optimal way. That is why this dataset presents six folders with information used as primary source in the case study of the Bajo Grau Bridge. First, the Hydrological Data is presented in XLS file, which contains the record of maximum monthly flows since 1960, provided by Autodema. Second, the Soil Data folder is included in XLS file, which shows the granulometry of the soil and the roughness of the channel, this information was obtained through a test pit in the riverbed. Third, the Topological Data in DWG file format, which contains the contour lines every one meter, this information was obtained through a topographic survey. Fourth, photos of the bridge are presented in JPG format, as part of the field visit. Fifth, photos of the granulometric study are included in JPG. Sixth, the hydraulic model in HEC-RAS is presented. Seventh, JPG photographs of the hydraulic models for the proposed scenarios are included.

The processing of the information, presented in detail in the scientific article "Hydrological Vulnerability Assessment of Riverine Bridges: The Bajo Grau Bridge Case Study", made it possible to determine the hydrological vulnerability of the Bajo Grau bridge as a high vulnerability, based on 10 criteria subdivided into physical and environmental vulnerabilities. The methodology used for this case study can be replicated in other riverbed bridges. The information contained in this dataset is intended to contribute to a better understanding of hydrological evaluations in river channels and their possible future implementation.
