*4.1. Preliminary Interdependencies Matrix*

The broad identification of interdependencies in the city of Lisbon considers seven main urban services or infrastructure for which a matrix of exposure and interdependencies was developed: electricity supply; telecommunications; water cycle; wastes; mobility; green and blue infrastructure; urban equipment; public lighting; and heritage areas. A simplified version of the matrix is presented in Table 4. Systematic analysis took several urban services into consideration, including plausible cascading events. Globally, runoff and flooding can directly or indirectly affect most services and infrastructure.
