A paved flood plain is now sited as example of European development.
At least let us know which river, so can we do a side by side scientific comparison. How long India will live and die by a selfie?
Unplanned and un-assessed urban developments can unravel the ecological system. Such developments on the flood plains of water bodies can obstruct the water rise and disturb the natural mechanism, causing flood. Paving over wetlands and flood plains removes some of the natural overflow capacity of the water system, forcing the excess water through the drains and open lands to spillover into cities and towns.
Encroaching flood plains doesn't gives a river space to spread the risen water, it results in massive floods, causing destruction to lives and property. Whenever heavy rains occur in an area whose soil and flood plains are wrongly prepared to handle the deluge, flooding can occur. Urban flooding, in maximum cases, is a reason of faulty developments and plannings and other ill human activities like encroachment, illegal sand mining, deforestation, un-assessed and unnatural beautification around water bodies.
Plants make up an ever-present natural defense against flooding. Grasses, shrubs and trees help keep healthy topsoil in place to absorb excess rainfall, and extensive root systems can absorb some excess water before it overflows a region. Naturally occurring waterways, flood plains, wetlands, tributaries, drains,etc all serve as safety valves for floods, drawing high waters away and dispersing them safely. Unfortunately, human activities like paving flood plains can disrupt these systems, increasing the likelihood and severity of floods.
Natural pavements don't need concrete makeover. If we will enter in the space of nature, nature would enter in ours. Nature's wrath is hard to bear. Tax payers' money should be invested in an organised and fruitful way than for digging concrete graves.
