History of Lysimeter Design and Use for Evapotranspiration Measurements
Lysimeters are devices for measuring percolation of water through soils and sampling soil water for chemical analyses. Lysimeters have been used for over 300 years to determine water use...
History of Lysimeter Design and Effects of Environmental Disturbances
A brief history of developments in lysimeter design is indicated. Disturbances introduced by the measurement system on the surrounding environment are discussed. The use of weighing lysimeters...
Large, Monolithic, Weighing Lysimeters
Monolithic lysimeters preserve existing vegetation and soil properties that can be destroyed by excavation and filling. Site preparation for constructing large, monolithic lysimeters includes...
Electronic Lysimetry for Hydrologic Studies
Purpose, definition and technology of lysimetry are in constant evolution. The flexure scale used here is a frictionless weighing machine, sturdy and precise. Electronics are necessary...
Lysimeter Studies in Irrigated Soils of South Eastern Australia
The Riverine Plain of south eastern Australia is an extensive, predominantly clay soil area with large surface irrigation schemes. Early lysimeter installations were used to estimate evaporative...
Water Balance Lysimetry at a Nuclear Waste Site
Lysimeters measure effects of soil, vegetation, and climate on water balance and groundwater recharge at a nuclear-waste site in arid-southcentral Washington State, USA. Data from 4 lysimeter...
Small Lysimeters for Documenting Arid Site Water Balance
