**LEAKY AQUIFER WITH CONSTANT WATER HEAD**

__Available conceptual schemes__:

1. Infinite aquifer;

2. Semiinfinite aquifer: recharge boundary;

3. Semiinfinite aquifer: non-flow boundary;

4. Strip aquifer: recharge boundary;

5. Strip aquifer: non-flow boundary;

6. Strip aquifer: one recharge and one non-flow boundary.

**Solutions:**

1. Solution based on leaky aquifer function;

2. Solution for drawdown in the fully penetrating observation well in leaky aquifer with account for the pumping well storage capacity;

3. Solution for water level drawdown in the pumping well in leaky aquifer with allowance for the pumping well storage capacity;.

4. Solution based on Green’s functions for strip aquifers.

**Typical scheme**

**LEAKY AQUIFER SYSTEM WITH ALTERNATING HYDRAULIC HEAD IN THE ADJACENT AQUIFER**

**Solutions:**

1. Solution for drawdown in the main aquifer;

2. Solution for drawdown in the adjacent (un-pumped) aquifer.

**LEAKY AQUIFER SYSTEM WITH ACCOUNT FOR AQUITARD STORAGE**

**Solutions:**

1. Solution for drawdown in the main aquifer, water level in the adjacent aquifer being constant or alternating during the test;

2. Solution for drawdown in the adjacent (un-pumped) aquifer;

3. Solution for drawdown in the aquitard, water level in the adjacent aquifer being constant or alternating during the test..

**PROFILE ANISOTROPIC AQUIFER WITHIN LEAKY AQUIFER SYSTEM**

**Solutions:**

1. Hantush’s solutions for drawdown in the partially penetrating well in profile anisotropic aquifer.
