Water Age

6 important questions on Water Age

Why do rain on snow events not cause huge amounts of streamflow in spring?

A big layer of snow will act like a soil. The snow will cool the rain down and it will refreeze or be stored in liquid form in the snow pack.

How is water age defined?

It's defined as the time elapsed since a water molecule entered a
hydrological system (e.g. time since it fell as rain in a catchment).

How to explain celerity with water?

Celerity (c) is the velocity of a flood wave.

What is transit time in catchment hydrology?


The age, since its time of entry, of water leaving the catchment.

How to calculate transit time?

Transit time =  store /  flux
