A weir was built on the Humber River (Ontario) to prevent a recurrence of a catastrophic flood. Flood management describes methods used to reduce or prevent the detrimental effects of flood waters. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff.
While gray infrastructure can be effective in preventing flooding-related damage [29] and can be economically valuable, [30] some models suggest that gray infrastructure may become less effective at preventing flood-related impacts in urban areas in the future as climate change causes flooding intensity and frequency to increase.

The aim of water security is to make the most of water's benefits for humans and ecosystems. The second aim is to limit the risks of destructive impacts of water to an acceptable level. [1] [2] These risks include for example too much water (flood), too little water (drought and water scarcity) or poor quality water. [1]
Flooding could impact food security for more than 5.6 million people across multiple African nations, a new study has found. While these impacts are usually negative, the researchers also ...
Damage to roads and transport infrastructure may make it difficult to mobilize aid to those affected or to provide emergency health treatment. Flooding can cause chronically wet houses, leading to the growth of indoor mold and resulting in adverse health effects, particularly respiratory symptoms. [46]
Climate change is altering the geographic range and seasonality of some insects that can carry diseases, for example Aedes aegypti, the mosquito that is the vector for dengue transmission. Global climate change has increased the occurrence of some infectious diseases. Infectious diseases whose transmission is impacted by climate change include, for example, vector-borne diseases like dengue ...
The floods produced a number of short- and long-term health consequences impacting the physical and mental wellbeing of victims. Poor access to healthcare due to insufficient medical infrastructure was compounded by a national healthcare strike [36] at the time of the disaster, further magnifying the negative health consequences.

Academic discussion of urban resilience has focused primarily on three threats: climate change, natural disasters, and terrorism. [7] [8] Accordingly, resilience strategies have tended to be conceived of in terms of counter-terrorism, other disasters (earthquakes, wildfires, tsunamis, coastal flooding, solar flares, etc.), and infrastructure adoption of sustainable energy.
