Werewolf said:From memory heavy rain over a short period of time is not as good as lighter rain over a prolonged period of time.
The reason is that heavy rain tends not to have time to settle into the ground (see my comment about floodplains), and tends to largely go straight back out to sea etc.
Lighter rain over a longer period has a chance to soak into the ground and get absorbed, thus working it's way into the water table.
This is correct
