What is hydrological output and input?

Hydrological output refers to the water that leaves a specific hydrological system, including processes such as evaporation, transpiration, and runoff into rivers, lakes, or oceans. Conversely, hydrological input encompasses the water entering the system, primarily through precipitation (rain and snow) and surface or groundwater inflow. Together, these inputs and outputs help determine the water balance and overall health of ecosystems, influencing water availability and management practices.
