Malakas & Chennai Floods

One of strongest Typhoon that I have experienced for so many years was Typhoon Malakas (No.16) that inundated Kyushu with a record high rainfall of 578mm in hyugu City, but all the rest of the place the rainfall yesterday is the range of 150-250mm is not any less. These places received 1 month rainfall on 9/20. Apart from power cuts, tree falls, while the reported rescue needed only for 6 people in Miyazaki should be greatly appreciated. While 70% of Japanese didn't experience the typhoon as it didn't reach Tokyo in the same vigor the power of nature is amazing to realize & get astonished!! Over a day after the severe summer,
All the rivers, streams & lakes operated at their full capacity& vigor is an amazing experience. Well, the drainage system is to appreciated that the roads that with in hours of the downpour everything's operating with business usual. The topology has been well utilized in the city planning!!!
I was just trying to draw a comparison with the Chennai inundation last year. The city received similar rains in a month period over different places. One would conclude that the preparedness are at different levels altogether. Though technically advanced, the country still have overhead electric transmission. The narrow roads & clustered matchbox houses posts similar threats. The rivers and streams are encroached heavily in many places. Housing in low level areas are a common site. Many old bridges that need strengthening are still high. With aging population concentrated out of Tokyo, old houses that are not strong pose threats to withstand such nature's might. The slackness of state governments are much comparable. Let me not get into it now as it will deviate the topic. But then there are differences. The land topology is not comparable. While its all plains in Chennai with height variations above sea level is few meters, most places in Japan are separated few tens of KMs has a steep drop in the height above level running from few hundred meters above sea level to few meters above sea level. Many rivers journey include only few hundred KMs but coming down across few hundred meters in height is notable. It's certainly aid in natural control of such inundation but then there is a great credit that should be attributed to the drainage system that has derived intelligence from with modern day technology. The cleanliness of the public helps in smooth drains and regular clearance of weeds across the rivers help in smooth flow.
Japan still maintains sizable area of its lands under forestry that certainly act as a regulator in such situations.
I'm not talking about the infrastructure all over here. Infrastructure helps in early alerts& preparedness. It helps in quick restoration back to normalcy.
In certain terms, when you look as how such nature's might can be handled is largely dependent on the society collective ability of love and coexistence with nature. Wherever there are deviations, the nature has punished when it was might & no technology nor infrastructure could circumvent the situation. Japan has been a classic example to derive various instances where they suffered brutally for their lack of natural coexistence.
Chennaites need to understand their topology, the intelligence of their city from the learnings over its history, The same is easier to say that do. The Chennai city did exhibit their strong attitude& hope they derive ways of coexistence with nature.
