What is defined as water that is in motion through the irrigation system?

The term that best describes water in motion through the irrigation system is dynamic water. This concept emphasizes the active flow and movement of water as it travels through various components of an irrigation setup, delivering moisture to plants effectively. Dynamic water is critical for irrigation practices, as it refers to the water actively being managed and utilized for agricultural or landscape purposes.

Static water refers to water that is not moving, such as water in a reservoir or groundwater that is not being drawn upon. Groundwater is found below the earth's surface, stored in aquifers, and while it can be a source of irrigation, it does not describe water in motion. Surface water relates to bodies of water like rivers and lakes, which can also be static depending on the context. Thus, dynamic water accurately captures the essence of water actively flowing through the system in irrigation practices.
