The relative advantages of embankment dams as compared to concrete dams include:

1. Adaptable to any type of foundation: Embankment dams can be built on a variety of foundations, including rock, soil, and even on weak or compressible soils. This is because the weight of the dam itself helps to compress the underlying soil and improve its strength.

2. Not Susceptible to damage by overtopping or burrowing of animals: Embankment dams are generally more resistant to damage caused by overtopping or the burrowing of animals. This is because they are typically made of earth or rockfill, which can withstand these types of disturbances better than concrete.

3. Suitable for narrow gorges with steep slopes: Embankment dams can be built in narrow gorges with steep slopes, where it would be difficult to construct a concrete dam. This is because the materials used in embankment dams can be compacted to fit the shape of the gorge.

4. Low maintenance cost and highly susceptible to settlement deformation: While embankment dams do require maintenance, the costs are generally lower than for concrete dams. However, they are more susceptible to settlement deformation, which can occur when the weight of the dam causes the underlying soil to compress over time. This can lead to changes in the shape of the dam and potentially compromise its stability.
