HYD151: Introduction to Field Methods in Hydrology, part 2
From Gregory Pasternack
On slides 15 and 16, I want to be clear that the terms "SM" and "depression storage" come into the water balance to the extent that they are changing. The left side of the question is influx and the right side outflux. Soil moisture storage and depression storage in and of themselves are not fluxes. It is when they change that there is a flux. Sometime they will go up and other times down. It is the addition or loss of water that is in the equation, not the storage itself.
