Depends on the situation.
Flowing into or out of a lake, or in a river Second Feet (acre feet/second).
CFS (cubic feet/second) for smaller situations.
Gallons/second or/minute or /hour for pumped water or water flowing in a pipe or hosepipe.
Liters/ unit of time
etc. etc.

There are many units in use. Most of them use a volume of water divided by a unit of time.
An exception, water flow in a toilet in the USA (and perhaps elsewhere) is measured in gallons per flush or liters per flush.
Examples of more conventional units would be:
gallons per hour
liters per second
barrels per minute
Any derived unit that divided a unit of volume by a unit of time might be useful.
To figure the amount of water required for irrigation, for instance, one might use a unit such as 100 cubic yards per year.

Depends if it's a mass flow rate, or a volume flow rate. Since water is incompressible, either is acceptable. For mass flow (mass flux) the symbolic is "m dot" or an m with a dot above it. In SI units, it's kg/s and in Imperial Units, it's slug/s (or lb-m/s "pound mass per second").
For volumetric flow, the symbol is "v dot" or a v with a dot above it. In SI units it's l/s (litres per second which is m^3/s as well), and in Imperial Units it's gpm (gal/min).

There are different units of flow rates. It could be volume per unit time as mentioned above, or mass/weight per unit time or even moles per unit time.

metric sistem is universal, and time too.
