TL;DR: In this article, the authors assess the quality of the analysis of visual sewer inspection data by analysing data reproducibility; three types of capabilities to subjectively assess data are distinguished: the recognition of defects, the description of defects according to a prescribed coding system and the interpretation of sewer inspection reports.

TL;DR: A method to represent and assess the flooding risk, using GIS and data gathered during operation and maintenance is proposed, and it is confirmed that blockages are not always directly due to the network itself and its deterioration.

TL;DR: Sewer asset management gained momentum and importance in recent years due to economic considerations, since infrastructure maintenance and rehabilitation directly represent major investments as discussed by the authors. But it is still a relatively new area.

TL;DR: In this paper, the authors proposed a new typology for improving multi-functionality of the urban green space as a solution to the challenge of limited area available, which suggests that the linking of greenspace components with urban green services could allow planners and managers to overlay the services expected, by selecting the best possible combination of greenspaces components.

TL;DR: The method mainly consists of two approaches: the top-down approach and the bottom-up approach that facilitates the identification of factors related to a sustainable UDS, the development priorities and the criteria available to managers.
