Flooding Before and Now by City Tech Blogger Rabea Begum

 

Why we are facing various natural disasters worldwide? Flooding is one of them. We are concern about the increasing amount of flood. If we look at the flood history, we can see that most of floods take hours or even days to develop. Some flood gives residents enough time to prepare or evacuate. There are other types of flood that create so quickly and with little warning. These flash floods are dangerous, suddenly turning a babbling brook into a thundering wall of water and sweeping everything in its path downstream. Disaster experts classify floods according to their likelihood of occurring in a given time period. A hundred-year flood is destructive than regular. These flash food is expected to happen only once every century.  But this is a theoretical number. In reality, this classification means there is a one-percent chance that such a flood could happen. Over recent decades, we can see that hundred years flood are occurring more often. Our scientists and geologists are assuming it is due to global warming but they are unable to find any solution for those frightening floods. If we look at the recent floods in Houston, California. We can see the destruction of the flood. It is being more than two months but still, Houston could not move forward. Sam Brody, a flood impact expert in Houston said: according to data from 1960 to now Texas had more life loss and property loss from floods than any other state in US. Houston is near the Gulf coast so, expert saying it is in annual risk. In 2008, there was another hurricane what cost 34-billion-dollar damage in Houston and killed 112 people. In Houston water retaining grasses replaced by non-absorbent planes, so water flow downstream. Water has more destructive power. It is hard for bridges, houses, trees to withstand against the water overflows. Those carries off very easily, even it can have carried off dirt from under a buildings foundation.

In Bangladesh, this year mid of the August 16 villages went under water, there was nothing left for people. More than 50000 people had no home, they are living under tree.  Although we are inventing lot of new things to make our life easier but we are really unable to deal with the natural disaster. And these increasing every year. We can warn people and evacuate them before flooding but we cannot really prevent damages. According to National Geographic the United States, “where flood mitigation and prediction is advanced, floods do about $6 billion worth of damage and kill about 140 people every year.”  A 2007 report by the Organization for Economic Cooperation and Development found that coastal flooding alone does some $3 trillion in damage worldwide. From this we can understand that how flooding is effecting worldwide. If United States is suffering this what we can assume for third world country. We should more focus on flooding and we have to really work on to help the world from flooding. We have to save people from this damage.
