Closing the water cycle gap - Sustainable ...

The main goal of this case study is to deliver information that allows actions to make urban environment more resilient and cost effective by using NBS in the urban area of the Igapó lake watershed, Londrina, Brazil. To achieve this goal, we have developed a strategy based on a set of actions axis dedicated to water quality analysis, hydro-climatology, land cover, and NBS interventions. Two additional axis involving environmental services, financial sustainability, stakeholders, and regulations were also planned to a second phase of the project. For the axes foreseen in the context of the RainSolutions consortium, the deliverables were as follows: D-01 Trend analysis for precipitation rates performed by the Mann-Kendall and Pettitt tests D-02 The rainfall intensity-duration-frequency (IDF) curves D-03 Water Quality Index (IQA) for two different rainfall regimes D-04 Adequacy of hydrological model to assess the effectiveness of NBS-interventions D-05 High resolution map of land cover classes D-06 Systematic literature review on NBS interventions in urban stormwater drainage D-07 Ranked potential benefits of NBS to control stormwater drainage D-08 Flood risk map for Igapó lake basin D-09 Potential NBS spatial allocation
