In one widely used interpretation of the Rational Method, the maximum possible peak discharge produced by a storm with a given return period is predicted by setting the storm duration equal to the time of concentration.

In southern Europe flood trends are generally negative. WebbThis is especially the case for micro hydro schemes which include a small catchment area. The 2013 floods in Uttarakhand, India, serve as a prominent example for this.
