There is an overall increasing trend of events exceedingand mm since the s. The immense loss of life and property caused by this event are testimony to the fact that the impacts of climate change can add significantly to the vulnerability of the locations and communities that face the danger of natural disasters anyway.
Economic During floods especially flash floodsroads, bridges, farms, houses and automobiles are destroyed. Sometimes insects and snakes make their ways to the area and cause a lot of havoc.
The IFRC — working with the Bangladesh Red Crescent Society and the Nepal Red Cross — has launched appeals to support almostvulnerable people with immediate relief and long-term help with water and sanitation, health and shelter. With the river hemmed in by perpendicular, concrete riverbanks as it flowed through Ahmedabad, there were serious threats of heavy flooding, and the administration reportedly evacuated more than 10, people.
In addition to this, flooding brings a lot of diseases and infections including military fever, pneumonic plague, dermatopathia and dysentery.

If the rain intensity exceeds 25 mm per hour and a high tide occurs, there is always a possibility of inundation. What can be done to make them more resilient? This is because the slope of the drains is supposedly designed to generate a self-cleaning velocity in the flow and is thus built to keep flooding relatively rare.
During —, there has been a three-fold rise in widespread extreme rainfall events, over the entire central belt of India from Mumbai to Bhubaneshwar, leading to a steady rise in the number of flash floods .

Economic During floods (especially flash floods), roads, bridges, farms, houses and automobiles are destroyed. EFFECTS OF FLOODS Floods are mostly caused by the intensive rainfall that incereases the water level dramatically and results excessive water overflow that might have some devastating effects on te endangerd areas.
