Overview

BARCELONA RESEARCH SITES

 

In the case study of Barcelona, a comprehensive multi-risk assessment was performed concerning several sectors and risk targets exposed to urban flooding. Risk assessment in Barcelona considered direct and indirect damage, as such as, tangible and intangible damages. Direct damages were also represented through qualitative (for the intangible impacts) and quantitative (for tangible impacts) maps achieved by sectorial and integrated detailed and calibrated models.

In this web-portal, hazard, vulnerability and risk maps elaborated for current (Baseline) and future (Business as Usual or BAU and Adaptation) scenarios are presented. These flood maps related to pluvial and coastal flooding focused on the following potential impacts:

1     Risk for people (Stability of pedestrians and vehicles)

2     Economic damage related to properties

3     Economic damage related to vehicles

4     Surface traffic disruption

5     Waste containers stability

6     Flooding of coastal critical infrastructures and services

Climate change scenarios were obtained by means of statistical spatial and temporal downscaling techniques on 20 future pluviometric series provided by 10 general atmospheric circulation models, forced by RCPs 4.5 and 8.5 scenarios, and previously validated for an historical control period (1976- 2005).

Business as usual scenario

A specific adaptation measure to guarantee the stability of containers during flood events has been proposed. Since 2016 fixation pieces (Figure 1) started to be installed in order to ensure the stability of containers when observed that just under the influence of their own weight could cause their instability in steep streets. The number of installed pieces is 147 so far, but 574 more are planned to be installed in the short term. However, these pieces may be used also to ensure stability of containers located in flat or low-slope areas, which may be potentially unstable when an urban flood occurs.

In order to increase the resilience of waste sector against urban floods caused by a 10-year return period and future rainfall conditions in Barcelona for an empty-containers scenario, 2,086 fixation pieces would be necessary to be installed. It has to be noted that a couple of pieces are needed to be installed per group of containers (Figure 1), thus two pieces have been taken into account per each group location where at least one potentially unstable container can be found. It would mean an estimated investment of 189,826 € (91 €/piece). Therefore, the twofold purpose of these pieces will be to ensure the containers' stability due to floodwaters in flat areas, and due to their own weight in steep streets.
