Abstract
Water is a critical issue, especially in developing countries’ cities that are grappling with climate change effects. Given the importance of water infrastructure assets in cities life and functionality, assessing their vulnerability and trying to make it resilient is an essential mission. To this end, this study has attempted to spatially analyze the urban water infrastructure assets vulnerability in Ahvaz, Iran, that has been hit by various climate change-related disastrous events over the past few years. Regarding this, the study has introduced two indicators, namely distribution and adaptation to determine the vulnerability of water infrastructure assets that have been recognized by applying a two-round Delphi survey. Findings indicate that, overall, there is no positive outlook and reliable capacity in terms of water resilience in Ahvaz because of distribution and adaptability of water infrastructure assets in the spatial area of the city and considerable parts of the city are vulnerable in face of any adverse event. This is mostly the case in Regions 1, 7, 3, 4 that feature a centralized and irregular form of water infrastructure assets distribution and proximity to non-adaptable land uses. Moreover, final spatial vulnerability map highlighted by two critical (hotspot) points, which shows the most vulnerable parts of the city for water infrastructure assets. The study highlights the need to make improvements urban water resilience due to reducing vulnerability, especially considering the spatial distribution and adaptation of water infrastructure assets in Ahvaz.
