The actual evapotranspiration as a function of the potential evapotranspiration and the soil moisture tension.

open access: yesNetherlands Journal of Agricultural Science, 1956
Lysimeter observations with a clay and a peat soil indicated that the actual evapotranspiration of grassland falls below the potential evapotranspiration while the soil is still drying, the fall being less for peat than for clay. The rate of reduction depends on the moisture tension of the soil and on the intensity of the potential evapotranspiration ...

Green roof seasonal variation: comparison of the hydrologic behavior of a thick and a thin extensive system in New York City

open access: yesEnvironmental Research Letters, 2016
Green roofs have been utilized for urban stormwater management due to their ability to capture rainwater locally. Studies of the most common type, extensive green roofs, have demonstrated that green roofs can retain significant amounts of stormwater, but

Validation of a spatial-temporal soil water movement and plant water uptake model [PDF]

open access: yes, 2014
Management and irrigation of plants increasingly relies on accurate mathematical models for the movement of water within unsaturated soils. Current models often use values for water content and soil parameters that are averaged over the soil profile ...

A substantial rise in the area and population affected by dryness in South Asia under 1.5 °C, 2.0 °C and 2.5 °C warmer worlds

open access: yesEnvironmental Research Letters, 2019
Millions of people in South Asia face water scarcity every year. Previous studies based on the multi-model ensemble mean reported a decline in dryness (the ratio of potential evapotranspiration and precipitation) in South Asia under the warming climate ...

Estimation of potential evapotranspiration and its variability in the upper and middle reaches of the Heihe River basin

open access: yesShui kexue jinzhan, 2015
On the basis of the MODIS LAI remote sensing products,China Meteorological Forcing Dataset and other multi-source datasets,the Shuttleworth-Wallace (S-W) model,which considers the temporal variation of leaf area index (LAI),was applied to estimate ...

POTENTIAL EVAPOTRANSPIRATION AND WATER BALANCE IN ICELAND

open access: yes, 1972
The paper describes the results of estimations of potential evapotranspiration (Ep) in Iceland using Penman's equation. The calculations are based on distribution maps for global radiation for the period 1958-1967 previously developed by the author, and ...

Variation of Potential Evapotranspiration with Elevation in Nepal

open access: yesMountain Research and Development, 1989
The broken topography of mountainous regions creates a complex mosaic of topoclimates. Spatial analyses of many climatic elements on a horizontal planar projection of such topography are almost meaningless. Therefore, in this study of potential evapo- transpiration (PET) in Nepal, the vertical dimension (elevation) was chosen as the basis for spatial ...
