The effectiveness of domestic rainwater harvesting (DRWH) systems to support urban flood resilience is analysed at the sub-catchment scale, according to a specific DRWH conversion scenario, under 4 degrees of urbanization, 3 drainage network configurations, 4 precipitation regimes and 3 return periods of the rainfall event. At this aim, a...

Green roofs are increasingly used as sustainable urban drainage system due to their positive impact on the storm water management. The mitigation consists in reducing the total outflow volume, while delaying the initial time of runoff and distributing the outflow over a longer time period. The retention, detention and infiltration processes...

Bioretention cells (BRCs) are a promising low-impact development (LID) practice that are commonly used in urban settings to improve the water quality and mitigate the hydrological effects of stormwater runoff. BRCs have been the subject of extensive research in order to better comprehend their function and improve their effectiveness. However,...

The main focus of the present study is to compare the use of Partial Duration Series (PDS) and the Annual Maximum Series (AMS) in extreme rainfall frequency analysis. The Generalized Extreme Value (GEV) and Generalized Pareto (GP) distributions are used to fit AMS and PDS, respectively. At this aim, the 1-minute rainfall data series collected...

In an existing urban environment, retrofitting low impact development (LID) solutions can provide an opportunity to address flooding and water quality problems. Taking into account the need to effectively estimate the impact of vegetated LIDs, particular attention has recently been given on the evapotranspiration (ET) process that is...

Rainwater Harvesting (RWH) systems are recognized as a widely accepted solution to save potable water in buildings. In addition, RWH systems may play an important role in mitigating the impact of increasing imperviousness in urban areas by contributing to increase both at-source retention and detention of storm water runoff. The chapter...
