Unconfined Aquifer
An unconfined aquifer is a type of aquifer where the water table is not confined by impermeable layers of rock or sediment. In this type of aquifer, water can flow freely in and out of the aquifer, making it more vulnerable to contamination and changes in water levels.
Dupit's assumptions
Dupit's assumptions are valid for unconfined aquifers. This is because in unconfined aquifers, water levels are directly influenced by factors such as precipitation and evaporation, which can lead to fluctuations in the water table. Dupit's assumptions are based on the assumption of steady-state flow conditions, which may not hold true for confined aquifers where the water table is more stable.
Why not other types of aquifers?
- Artesian aquifer: Artesian aquifers are confined aquifers where water is under pressure due to a layer of impermeable rock. Dupit's assumptions may not be valid for artesian aquifers as the flow conditions are different.
- Confined aquifer: Confined aquifers are separated from the surface by impermeable layers of rock. Dupit's assumptions may not be valid for confined aquifers as the water table is not directly influenced by surface conditions.
- Leaky aquifer: Leaky aquifers have layers of varying permeability, allowing water to flow between different aquifer layers. Dupit's assumptions may not be valid for leaky aquifers as the flow conditions are more complex.
In conclusion, Dupit's assumptions are valid for unconfined aquifers where the water table is directly influenced by surface conditions and where steady-state flow conditions can be assumed.

Dupuit’s equation used to compute the discharge through an unconfined aquifer. Following are the various assumptions considered to derive the equation:
- The aquifer is unconfined.
- The aquifer has an infinite areal extent.
- The aquifer is homogeneous, isotropic and of uniform thickness over the area influenced by the test.
- Prior to pumping, the piezometric surface is horizontal over the area that will be influenced by the test.
- The aquifer is pumped at a constant discharge rate.
- The well penetrates the entire saturated thickness of the aquifer.
- The gradient between the pumping well and monitoring wells is at steady-state.
- The velocity of flow is proportional to the tangent of the hydraulic gradient instead of the sine as it is in reality.
- The flow is horizontal and uniform everywhere in a vertical section through the axis of the well.
∴ Dupuit’s assumptions are valid for an unconfined aquifer.
