Urban flooding occurs when water flows into a city or town faster than it can be drained, absorbed into the soil or moved to and stored in a man-made lake or reservoir. While excess rain is a direct factor contributing to the flooding, the actual causes of the flood itself have to do with old sewer systems, lack of drainage, and high population growth. This long-term planning must include forecasts of expected weather. Urban flooding is specific in the fact that the cause is a lack of drainage in an urban area. Urban flooding is caused when the inflow of storm water in urban areas exceeds the capacity of drainage systems to infiltrate storm water into the soil or to carry it away. As a result, the peak discharge, volume, and frequency of floods increase in nearby streams. 1. Urban flooding has been observed worldwide and it is becoming a regular event in Indian cities too, as can be seen in the list below3. This global climate change has not only impacted several lives but is also very crucial from environmental aspects. We can split the definition into three separate components: urban flooding is (1) caused by rain that (2) falls on impervious surfaces and (3) overwhelms local stormwater drainage capacity. Moreover, With the frequent occurrence of extreme weather, the acceleration of urbanization and the low standard of flood control and drainage in most cities, urban flood problem will be further deteriorated in the future [1,2]. Urban Flooding has been a cause of concern throughout the world. Flooding Causes. Urban flooding is the inundation of land or property in a built environment, particularly in more densely populated areas, caused by rainfall overwhelming the capacity of drainage systems, such as storm sewers.Although sometimes triggered by events such as flash flooding or snowmelt, urban flooding is a condition, characterized by its repetitive and systemic impacts on communities, that can . Hint: It's not just rain. where claims have been paid out, and in some cases the cause of the damage, and therefore where risks and exposure are most significant. Many of the common causes of urban flooding, including storm surges, heavy precipitation, and river overflow, are expected to increase in frequency and severity as climate change intensifies and causes increases in ocean and river levels. Urban Flooding has been a cause of concern throughout the world. And the consequences of flooding can be savage. As the atmosphere warms, there is more evaporation and more water available for rain, which contributes to changing weather patterns and flood risks.
