What is the term for the water level when a pump is operational?

The correct term for the water level when a pump is operational is "Dynamic." When a pump is actively lifting or moving water, the condition of the water level is referred to as dynamic water level. This is because the water level changes as the pump operates and influences the water pressure within the system.

Conversely, static water level refers to the depth to which water rises in a well when no water is being pumped. Flowing is a more general term that does not specifically describe the water level in relation to pump operation. Pumping indicates an action but does not define the state of the water level specifically. Understanding these definitions helps in assessing groundwater resources and the effects of pump operation on water supply systems.
