A stream’s water level abruptly rises (or drops) by and next remains constant. In the case of level oscillations, the interaction between a river and an aquifer can be described by a general equation, which is based on transient relationships for a single perturbation and the principle of superposition:
where f is a function describing level variations in the aquifer (see below).
