This bridge is located in Mankulam - Mulathive road, where I worked as the Consulting Bridge Engineer for the project in 2012/13
|A Bridge on a river where you can not find a single drop of water.|
While structure was under construction, few visitors to the site raised their eyebrows on the requirement of a bridge at particular location. However, the Hydraulic studies of the area gave us a very different figures which are drastically differ from the depiction of the picture.
I was fortunate to witness the theory meets reality. During the time of project execution, bridge met its highest flood which it was designed and stood against it.
|Same bridge but with many drops of water|
The bridge was designed with a 600mm of minimum freebord height for the high flood level and it is adequately designed as seen in the picture.
However, at the time of flood , the bridge was not in its completed form. The approach roads and the embankment protection measures were not completed. As a result, the embankment was damaged and later it was rectified.
Looking forward to write more in my next post on the subject of bridge protection measures that we took after the rainy season.
