Given the basic characteristics of a pressurized gravity conduction line (extension, celerity), permanent regime (water velocity) and valve (closure time, assumed linear), estimates the extreme transient heads that will occur at the valve and at midway.

This method is applied to closing valve time equal or superior to $10\cdot \frac{L}{a}$, with $L$ been the extension and $a$ is the celerity.
