Flood Resistant Houses

Abstract

Unusual high stage of river is called flood. In flood, the water level rises to an extent in which water starts spilling over the bank and spreading to the flood plains. The frequency and intensity of floods has intensified in the country over the years primarily due to encroachment of flood plains because of obvious advantages of water supply and irrigation. Flood causes extensive damage to infrastructure, the economy and devastation to human settlements. Heavy rains during the monsoon season lasting between June and September are a common peril hazard in North-East India. Usually 80 to 90 percent of the annual rain falls over most parts of the country, due to monsoon circulation cause severe floods in some of the Indian rivers due to cyclonic precipitation. Out of the total geographical area of 329 mha of India, more than 40 mha is flood prone. In the past three decades, about 481 natural disasters struck India in which 184 were flood disasters affecting millions of people and took over 4000 lives. According to the climate change reports from inter-governmental panel, warn that the climate change in the country will lead to an increase in frequency, intensity, spatial extent, duration, and timing of extreme weather events. For preparing to minimize the flood damages, many techniques can be adopted in which construction of flood resisting houses is an important step to be worked on. Measures to design of flood resistant houses and some case are discussed and described in the present paper.
