When high hydraulic gradients exist, there is a possibility that the seeping water may cause internal erosion within the dam, especially if the soil is poorly compacted.
View all questions of this test
Erosion of soil material can work its way back into the embankment, creating voids in the form of channels or ‘pipes,’ thus impairing the dam’s stability.
This form of soil erosion from the structure’s foundation is referred to as piping and occurs when water flows upwards, resulting in zero effective stress.
The phenomenon is seen in cohesionless soil, which loses its shear strength due to a high upward hydraulic gradient.
The piping failure in a hydraulic structure can be prevented by-
- Increasing the stress due to the weight of the structure
- Increasing the creep length of the flow of water
- By introducing an inverted filter on the downstream side

Piping:
Piping is a phenomenon in which seepage water removes material from the foundation of a structure, causing instability. Here is an explanation of this phenomenon:
Causes:
- Piping occurs when water flows through soil beneath a structure, carrying away soil particles and creating voids.
- It is often triggered by high water flow rates, inadequate soil compaction, or the presence of fine-grained soils that are easily eroded.
Effects:
- Piping can lead to the formation of underground cavities, weakening the foundation of the structure.
- As more material is removed, the foundation becomes unstable, increasing the risk of structural failure.
Prevention:
- To prevent piping, proper drainage systems should be installed to control water flow around the structure.
- Selecting suitable foundation materials and ensuring proper compaction can also help prevent piping.
In conclusion, piping is a serious issue that can compromise the stability of structures. It is important to understand the causes and effects of piping and take preventive measures to ensure the safety and longevity of the structure.
