Chapter 4: Principles of Ground-Water Flow
"Ground water possesses energy in mechanical, thermal, and chemical forms. Because the
amounts of energy vary spatially, ground water is forced to move from one region to another
in nature's attempt to eliminate these energy differentials. The flow of ground water is
thus controlled by the laws of physics and thermodynamics. To enable a separate
examination of mechanical energy, we will make the simplifying assumption that the
water is of nearly constant temperature. Thermal energy must be considered, however,
in such applications as geothermal flow systems and burial of radioactive hear sources."
