definition
  • LYSIMETERS are types of evaporation gauges that consists of a tank or pan of soil placed in a field and manipulated so that the soil, water, thermal, and vegetative properties in the tank duplicate as closely as possible to the properties of the surrounding area; uses various methods to determine the reductions in the weight of the instruments so that water loss due to evapotranspiration can be computed; some lysimeters deal with the studies of chemical leaching and others like shear-stress lysimeters have been developed to measure the surface momentum flux from the atmosphere.

Abstract from DBPedia
    A lysimeter (from Greek λύσις (loosening) and the suffix -meter) is a measuring device which can be used to measure the amount of actual evapotranspiration which is released by plants (usually crops or trees). By recording the amount of precipitation that an area receives and the amount lost through the soil, the amount of water lost to evapotranspiration can be calculated.Lysimeters are of two types: weighing and non-weighing.
