Simplified hydrologic cycle. The sun is the primary source of energy for all hydrometeorological processes. Solar energy evaporates water from the oceans (and a very little from the land). Plants add some water vapor to the atmosphere through transpiration. The water vapor condenses into clouds and finally precipitaiton, and most of it falls ...Hydraulic Head. Hydraulic head is one of the key variables in describing a groundwater system. It represents the mechanical energy per unit weight of fluid in the system. Hydraulic head, h, is defined as: , where hp is the pressure head and hz is the elevation head.
