Absolutely Yes, factors of seepage are very important to determine before the construction of a dam or even after the construction of the dam for maintenance work.
Electrical resistivity method is used to determine the amount of seepage and depth of seepage.
As a civil engineer, it’s our responsibility to provide higher safety.
Seepage under the embankment is very much dangerous as compared to concrete dams because embankments are built on a very soft material which is easily scoured and it is very vulnerable for the influence of water.
On other side concrete dam, is built on hard strata and even the defective dam which not the endangered by passing of water from the underside.
Following are the methods for controlling seepage
- Providing drainage
- By reducing the seepage with some proper methods.
- Largely use of filters for preventing the piping and heave
