Data for flood management techniques and challenges during flash flood in the Bihar

A flash flood is such an event which results into loss of life and property to people mostly living in countryside. This event mostly takes place in northern part of Bihar due to surplus amount of water being discharged by Nepal in rivers like Gandak river which ultimately increases the current of the river. This condition is even badly hit by erosion of banks of rivers which increases the risk of collapse of bunds which eventually pushes water in the villages which affects the life of people. So, in Anti-Erosion work engineers basically try to look into this problem and they have come up with certain solution like construction of Teeth Bars whose main objective is to deflect the water away from the banks of the river.
Water Resources Department of various states take preventive measure to control flood and certain precaution are taken up especially at the banks of river which are vulnerable to erosive action of the river. Such measures include building of teeth bar along the banks of the river which is most vulnerable to erosive action of the river, which would otherwise cut down the bandh and flood down the plain area. Such teeth bar helps in deflecting the flood causing water and hence banks are being protected from being cut down. Apron design is the key feature of this preventive measure which is done by launching nylon crate in the river for making the base over which nylon crate and gabion would be placed.
