“…This, associated with extreme climate changes, increases the floods and droughts associated risks, since it reduces the most favourable area for water infiltration [2,3]. This occurrence affects the urbanization hydrologic factors by increasing the surface runoff, the water quality deterioration and concentration of pollutants, reducing groundwater recharge [4][5][6][7][8][9]. The porous asphalt use in surface layers of road pavement is one of the solutions used worldwide to decrease the caused effects.…”

The increase in urbanization and climate change projections point to a worsening of floods and urban river contamination. Cities need to adopt adaptive urban drainage measures capable of mitigating these drivers of change. This study presents a practical methodology for a modular design of bioretention systems incorporating land use and climate change into existing sizing methods. Additionally, a sensitivity analysis for these methods was performed. The methodology was applied to a case study in the city of Sao Carlos, SP, Brazil. Three application scales were evaluated: property scale (PS), street scale (SS) and neighborhood scale (NS) for three temporal scenarios: current, 2015–2050 and 2050–2100. The choice of the sizing method was the factor with greatest influence on the final bioretention performance, as it considerably affected the surface areas designed, followed by the hydraulic conductivity of the filtering media. When analyzing the sensitivity of the parameters for each method, the runoff coefficient and the daily precipitation with 90% probability were identified as the most sensitive parameters. For the period 2050–2100, there was an increase of up to 2×, 2.5× and 4× in inflow for PS, SS and NS, respectively. However and despite the great uncertainty of future drivers, bioretention performance would remain almost constant in future periods due to modular design.

“…Urbanization significantly impacts the water environment with increased runoff and the degradation of water quality (Goonetilleke et al, 2005). The changes to rainfall characteristics will result in complexity in relation to stormwater management in urban areas and, by implication, the mitigation of flood damage (Ghazal et al, 2014). In Mumbai, it was estimated that by 2080, due to climate change, the flood magnitude is expected to be twice that of a flood event that occurred in 2005 (Ranger et al, 2011).…”

Transdisciplinary approaches in water are important to ensure water security to everyone around the world. Recently, Young Water Professionals (YWPs) training was carried out to impart learning in transdisciplinary approaches. Besides online workshops and lectures, the training program included the Situation Understanding and Improvement Project (SUIP). Through SUIP, YWPs were able to implement the transdisciplinary approaches learnt during lectures and workshops. The SUIP selected by one of the groups of YWPs was related to the flooding experienced by the residents of Chennai, India. Flooding is a very common phenomenon having its occurrence across the world with varying severity and magnitude because of changes to the use of river floodplains, changing the land use pattern, encroachment of waterbodies, and the impact of climate change on water resources. Chennai City in Tamil Nadu, India, with a population of about 6.5 million is facing frequent flooding because of extreme rainfall events and the presence of three rivers within the city and is also facing an acute shortage of water which also needs to be addressed for its sustainable development. This study used transdisciplinary approach to understand 2015 flooding in Chennai and made several recommendations to improve the flood management in Chennai including an early warning system. The YWP training and the concept of SUIP significantly enhanced the outcomes from this study.
