This concerning trend underscores the urgent need to understand the root causes of urban floods and implement effective mechanisms for preparedness to mitigate the associated risks. Urbanization, climate change, inadequate drainage systems, and alterations in land use patterns are among the key factors contributing to the rising incidence of flooding in urban areas. As urban populations continue to grow, the expansion of impervious surfaces exacerbates runoff, overwhelming drainage infrastructure and leading to widespread inundation during intense rainfall episodes. Additionally, climate change-induced shifts in precipitation patterns contribute to the unpredictability and severity of rainfall, further intensifying the vulnerability of urban environments to flooding.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\"><p><strong>Tag: <\/strong>Disaster and disaster

class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>Urban flooding is not just \u201cflooding of urban areas\u201d. It is significantly different from normal flooding\/rural flooding. As urbanization leads to developed catchments it causes increased flood peaks from 1.8 to 8 times and flood volumes by up to 6 times. Urban areas are densely populated and people living in vulnerable areas suffer due to flooding, sometimes resulting in loss of life. It is not only the event of flooding but the secondary effect of exposure to infection also has its toll in terms of human suffering, loss of livelihood and, in extreme cases, loss of life. Recent water logging in Gurgaon, urban flood in Mumbai and Srinagar shows the increasing intensity of urban flood disasters in India.&nbsp;&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><a href=\"https:\/\/edukemy.com\/upsc\/upsc-essay?utm_source=Blog&amp;utm_medium=Banner&amp;utm_campaign=Essay\" target=\"_blank\" rel=\"noreferrer noopener\"><img decoding=\"async\" width=\"1280\" height=\"300\" data-src=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/10.png\" alt=\"\" class=\"wp-image-42412 lazyload\" data-srcset=\"https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/10.png 1280w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/10-1170x274.png 1170w, https:\/\/edukemy.com\/blog\/wp-content\/uploads\/2024\/06\/10-585x137.png 585w\" data-sizes=\"(max-width: 1280px) 100vw, 1280px\" src=\"data:image\/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==\" style=\"--smush-placeholder-width: 1280px; --smush-placeholder-aspect-ratio: 1280\/300;\" \/><\/a><figcaption><a href=\"https:\/\/edukemy.com\/upsc\/upsc-essay?utm_source=Blog&amp;utm_medium=Link&amp;utm_campaign=Essay\">UPSC Essay Course<\/a><\/figcaption><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Reasons_behind_urban_flooding\"><\/span><strong>Reasons behind urban flooding:<\/strong>&nbsp;&nbsp;<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li>A special feature in India is<strong> heavy rainfall during monsoons<\/strong>. There are other weather systems also that bring in a lot of rain. Storm surges can also affect coastal cities\/ towns.\u00a0<\/li><li>The <strong>urban heat island effect<\/strong> has increased rainfall over urban areas. Global climate change is resulting in changed weather patterns and increased episodes of high-intensity rainfall events occurring in shorter periods.\u00a0<\/li><li>Stormwater drainage systems in the past were designed for rainfall intensity of 12\u201320 mm. These capacities get easily overwhelmed whenever rainfall of higher intensity is experienced. Further, the systems very often do not work to the designed capacities because of very poor maintenance.\u00a0<\/li><li>Encroachments are also a major problem in many cities and towns. The flow of water has increased in proportion to the urbanization of the watersheds. Ideally, the natural drains should have been widened (similar to road widening for increased traffic) to accommodate the higher flows of stormwater. But on the contrary, there have been large-scale encroachments on the natural drains and the river floodplains. Consequently, the capacity of the natural drains has decreased, resulting in flooding.\u00a0<\/li><li>Improper disposal of solid waste, including domestic, commercial, and industrial waste, and dumping of construction debris into the drains also contribute significantly to reducing drainage capacities.\u00a0<\/li><li>The presence of<strong> impervious cover near trees<\/strong> and on road pavements also reduces water runoff.\u00a0<\/li><\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Measure_to_reduce_the_risk_of_urban_flooding\"><\/span>Measure to reduce the risk of urban flooding:\u00a0\u00a0<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<ul class=\"wp-block-list\"><li><strong>Cleaning of drainage:<\/strong> Before monsoon, we need to clean the drainage system of every city and make sure the drainage system is not choked which can potentially create a barrier for running flood water.\u00a0\u00a0<\/li><li><strong>Complete ban of plastic:<\/strong> Banning plastic is required to keep all drainage systems choke-free.
