Comparative analysis of 15 major reference evapotranspiration models based on weighing lysimeter measurements for two different grass species grown in three soil textures

Irrigation and Drainage, 2022
In this study, 15 models in the combination, radiation, and temperature‐based groups were evaluated for three consecutive years (2017–2019) with lysimetric measurements in a semi‐arid region of Iran.

Low-Cost Electronic Weighing Lysimeters

Transactions of the ASAE, 1990
ABSTRACT Evapotranspiration research lysimeters with 1 nfi area and 1.2 m depth were designed and constructed using commercially available cantilever load cells. These lysimeters were operated continuously for a three-year period at the Drainage Research Farm of Utah State University. Resolution of daily measurements of evapotranspiration (Et) from the

Mechanical balance-electrical readout weighing lysimeter

Boundary-Layer Meteorology, 1971
As part of the research programme of the Atmospheric Environment Service, a large, sensitive weighing lysimeter was constructed on the Atmospheric Environment Service research site north of Toronto. Features of the instrument include: measurement of runoff, percolation, drainage of water held in tension, addition of water from below during dry ...

Noise Reduction Methods for Weighing Lysimeters

Journal of Irrigation and Drainage Engineering, 2009
Mechanical vibration of the grass and crop weighing lysimeters, located at the University of California West Side Field Research and Extension Station at Five Points, Calif. generated noise in lysimeter mass measurements and reduced the quality of evapotranspiration (ET) data.

Design and Installation of Large Weighing Lysimeters

Transactions of the ASAE, 1985
ABSTRACT THE design, construction, installation, and calibration of two large weighing lysimeters are described. The lysimeters have a surface area of 4 m2 and a net soil profile depth of 2 m. The soil profile was constructed by careful packing. Each lysimeter rests on a sensitive scale capable of measuring the total mass of approximately 20 Mg to the ...

Design and Construction of Large Weighing Monolithic Lysimeters

Transactions of the ASAE, 1988
ABSTRACT FOUR large, weighing, monolithic lysimeters were designed, constructed and installed at Bushland, TX. Each lysimeter has a surface area of 9 m^ and a soil depth of 2.3 m. The soil within each lysimeter is an undisturbed monolith of Pullman clay loam. Each soil monolith has a mass of approximately 45 Mg, including the container mass.
