Flood management can include flood risk management, which focuses on measures to reduce risk, vulnerability and exposure to flood disasters and providing risk analysis through, for example, flood risk assessment. [1] Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and ...
Flood mitigation is a related but separate concept describing a broader set of strategies taken to reduce flood risk and potential impact while improving resilience against flood events. As climate change has led to increased flood risk an intensity, flood management is an important part of climate change adaptation and climate resilience.
As of 26 September 2019; the monsoon floods affected 13 districts, killing at least 2 people, injuring 6 others, and about 116,000 people were affected. [16] One casualty was reported in the Galle District and the other one was reported in Kolonnawa , where a teenager drowned in the flood water. [ 17 ]
Any activities that enlarge the impermeable surface areas in a city can increase the flood risk. Impermeable surface areas are generated through soil sealing as this reduces drainage options of floodwaters. [3]: 925 As the pace of urbanization accelerates around the world, urban flooding has the potential to affect more people. [3]: 925
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 ...
Note: Some of these floods and landslides may be partially caused by humans – for example, by failure of dams, levees, seawalls or retaining walls. This list does not include the man-made 1938 Yellow River flood caused entirely by a deliberate man-made act (an act of war, destroying dikes).
The 2019–2020 Congo River floods resulted from torrential rains from October 2019 to January 2020 that caused the overflow of the Congo and Ubangi rivers, floods and landslides throughout the Democratic Republic of Congo (DRC) and Republic of Congo (RoC) and led to the displacement of hundreds of thousands of people.

Climate models do not simulate the water cycle very well. [15] One reason is that precipitation is a difficult quantity to deal with because it is inherently intermittent. [6]: 50 Often, only the average amount is considered. [16] People tend to use the term "precipitation" as if it was the same as "precipitation amount".
