Rotterdam, a city located at the delta region and only 35 km to the sea, suffers from increasingly frequent intensive rainfall due to the climate change. The pluvial flood it causes overwhelms the urban drainage system first and then damages the transport systems. Residential and industrial infrastructures in the city and local ecology will be influenced as well. Ethically, it causes anxiety and conflictions among citizens, even triggers people’s unsatisfaction and denouncement. Solutions provided here focus on urban drainage and discharge system, water retention facilities, infiltration zones/ green spaces, protection of vulnerable infrastructures and government regulations. This report consists of seven parts: introduction to pluvial flood, affected parts of urban networks, condition till 2050 under climate change, ethical consequences, solution strategies, ethical implications of solutions and effect monitor.
