Effects of climate change on the urban tourist and coastal area of Viña del Mar: Survey of damage for flooding by storm surge and perception of security
Many coastal cities are dealing today with different problematics due to climate change. In the case of Viña del Mar, there is an increase in strong swell, making this a high visibility problematic zone.

| description |
Many coastal cities are dealing today with different problematics due to climate change. In the case of Viña del Mar, there is an increase in strong swell, making this a high visibility problematic zone. This work analyses the effects of recurrent and strong waves in urbanized coastal lands highly visited by tourists (Avenida Perú, Población Vergara, Viña del Mar), and the perception of security of inhabitants and tourists. By historical wave data analysis, a significant event survey, and a safety perception survey, this work highlights the negative impact of these events over the urban infrastructure located next to the coastal line, including urban furniture, residences, hotels, cars and stores in the last decades. A negative safety perception on infrastructure and coastal defenses performance was found, as well as a strong need to adapt the infrastructure to reduce vulnerability. The analyzed infrastructure has not been adapted to the risk of floods. This situation warns of the obsolescence of predominant typologies, which are constantly affected either in winter or summer times. Some solutions as the incorporation of new flood-adapted building typologies, relocate critical infrastructure and services, incorporate soft coastal defenses solutions, together with a reinforcement of codes, are discussed in order to reduce the effects of future extreme wind wave events. |

Las ciudades costeras afrontan actualmente diversas problemáticas debido a los efectos del cambio climático. En el caso de la ciudad de Viña del Mar, se visualiza un aumento en la frecuencia e intensidad de eventos de oleaje extremo, por lo que la zona costera será donde este problema tendrá una mayor visibilidad. Este trabajo analiza el impacto de un evento de marejadas en una localidad densamente poblada y visitada por turistas (sector Avenida Perú, Población Vergara, Viña del Mar), así como de la percepción de seguridad que tienen residentes y turistas ante esta problemática. Mediante el análisis de datos de marejadas históricas, levantamiento de daños de un evento significativo y una encuesta de percepción de seguridad, se destaca el impacto negativo que tienen estos eventos en la infraestructura urbana situada contigua a la línea de costa, incluyendo mobiliario urbano, residencias, servicios turísticos y automóviles. Se constató una percepción de seguridad negativa y una necesidad de adaptación de infraestructura para reducir vulnerabilidad. La infraestructura analizada no se ha adaptado al riesgo de inundaciones costeras. Esta situación advierte de la obsolescencia de tipologías predominantes, las cuales son constantemente afectadas tanto en el período estival como invernal. Finalmente se discuten diversas opciones de adaptación de infraestructura, códigos de construcción, relocalización y uso de defensas blandas para reducir los efectos de futuros eventos de oleaje extremo.
