Wavelet analysis of soil water state variables for identification of lateral subsurface flow: Lysimeter vs. field data

open access: yesVadose Zone Journal, 2021
Preferential and lateral subsurface flow (LSF) may be responsible for the accelerated transport of water and solutes in sloping agricultural landscapes; however, the process is difficult to observe.

Evapotranspiration and crop coefficient of basil determined by weighing lysimeters [PDF]

open access: yesHorticultura Brasileira, 2019
ABSTRACT The basil (Ocimum basilicum) crop is of great importance for trading as fresh or dried condiment for human consumption and essential oil for pharmaceutical and cosmetic industries. Water excesses and deficits can affect biomass production of plants, making it necessary to use the correct amount of water for each crop.

An overview of the experimental research use of lysimeters

open access: yesEnvironmental & Socio-economic Studies, 2019
The lysimeter is most often defined as a box filled with soil with an intact structure for measuring the amount of infiltration and evapotranspiration in natural conditions.

Evapotranspiration from Maize Studied Using Weighing Lysimeters

open access: yesGuan'gai paishui xuebao, 2021
【Objective】 Evapotranspiration is important not only as a component of the hydrological cycle but also for its role in modulating crop growth. The purpose of this paper is to measure the evapotranspiration of spring maize using weighing lysimeters and analyze its relationship with the yield and water use efficiency of the crop.

Construction and calibration of weighing lysimeters with an automated drainage system

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental
Quantification of the drained volume is one of the difficulties involved in using weighing lysimeters. Typically, this volume is measured by accessing a moat at the base of a lysimeter.

Correction of Eddy Covariance Based Crop ET Considering the Heat Flux Source Area

open access: yesAtmosphere, 2021
Eddy covariance (EC) systems are being used to measure sensible heat (H) and latent heat (LE) fluxes in order to determine crop water use or evapotranspiration (ET). The reliability of EC measurements depends on meeting certain meteorological assumptions;

Increasing Evapotranspiration on Extensive Green Roofs by Changing Substrate Depths, Construction, and Additional Irrigation [PDF]

open access: yes, 2019
Urban environments are characterized by dense development and paved ground with reduced evapotranspiration rates. These areas store sensible and latent heat, providing the base for typical urban heat island effects.
