In urban planning and design, blue space (or blue infrastructure) comprises areas dominated by surface waterbodies or watercourses. In conjunction with greenspace ( parks , gardens , etc. specifically: urban open space ), it may help in reducing the risks of heat-related illness from high urban temperatures ( urban heat island ).

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 [27] and can be economically valuable, [28] 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.

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 ...
Severe flooding in Iowa led to evacuations of many homes. In eastern Iowa along the Iowa River and Cedar River, flooding was expected to exceed that of the Flood of 1993. [16] Flooding also forced the closure of a number of roads throughout the state, reaching the point where travel was not advised in some parts of the state.
The floods inundated low-lying residential areas in Vijayawada and several villages downstream, causing significant damage to infrastructure, homes and agricultural land. [8] Historical data indicates that this flood event surpassed previous records, with only the 2009 and 1998 floods coming close in terms of discharge levels.
