Flow rate is the speed at which the volume of water moves through an aquatic ecosystem. It refers to the amount of water that can move from one region of the aquatic system to other in a given period of time. The flow of water affects the temperature, salinity of water and the living organisms surviving in an aquatic ecosystem.

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
