Village of Aurora was never flooded before the Year 2016. Ever since a new development in the
neighboring city, the area started to experience the flood in 2017. An investigation was launched
and found that the new development was the cause of the flood for the downstream area
including the Aurora Village. What measures can be applied to mitigate the flood for the
downstream area?
Solution
The major development project which causes the flooding of the down stream areas are dams,
dams have both advantages and disadvantages in their own way, compared to the disadvantages
the advantages are more when compared in the long run, one of the major problem is flooding of
villages in the down stream areas and a lot of ecosystem is submerged while construction of the
dam, the following measures can be taken to prevent the flooding of areas in the down stream:
1. Design the dam in such a way that there would be minimum impact on the environment and
the population living nearby
2. If the soil is not fertile, then stabilize the soil if not done the erosion takes place
3. Remeandering of rivers is to be done so that they are in their natural course itself
4. Provide more reservouir for storing of water
5. Provide an alarming system for reducing of impact on the surrounding population
6. Provide sufficient number of crest gates to control the flow in case of floods
7. Construct the buildings above the ground level in flood prone areas, so that the houses will not
be damaged
The above measures would be sufficient enough to diminish the effect of flood in a given area..
