Hydrologic regulation of plant rooting depth
(National Academy of Sciences, 2017-10-03)
Plant rooting depth affects ecosystem resilience to environmental stress such as drought. Deep roots connect deep soil/groundwater to the atmosphere, thus influencing the hydrologic cycle and climate. Deep roots enhance ...
Water Relations and Foliar Isotopic Composition of Prosopis tamarugo Phil., an Endemic Tree of the Atacama Desert Growing at Three Levels of Water Table Depth
(Frontiers Media, 2016)
Prosopis tamarugo Phil. is a strict phreatophyte tree species endemic to the "Pampa del Tamarugal", Atacama Desert. The extraction of water for various uses has increased the depth of the water table in the Pampa aquifers ...
Evolution equation for short surface waves on water of finite depth
(Elsevier B.V., 2009-08-15)
We address the question of determining the evolution equation for surface waves propagating in water whose depth is much larger than the typical wavelength of the surface disturbance. We avoid making the usual approximation ...
Miles’ mechanism for generating surface water waves by wind, in finite water depth and subject to constant vorticity flow
(2021-12-01)
The Miles’ theory of wave amplification by wind is extended to the case of finite depth h and a shear flow with (constant) vorticity Ω. Vorticity is characterised through the non-dimensional parameter ν=ΩU1/g, where g the ...
Contribution of leaf water uptake to transpiration and water status in arid ecosystems
(International Society for Horticultural Science, 2020-12)
Foliar water uptake (FWU) could be relevant for plants, allowing them to use alternative water sources than the primary one that is soil water uptake and thus prevent dehydration especially during the dry season in ...
Prosopis tamarugo Phil.: a native tree from the Atacama Desert groundwater table depth thresholds for conservation
(Sociedad de Biología Chile, 2015)
Prosopis tamarugo Phil. is a legume tree native to the Atacama Desert, Chile. Tamarugo has physiological characteristics that are highly adapted to extreme life conditions in the Pampa del Tamarugal. Null precipitation ...
Estimations of rooting depths and sources of plant-available water (PAW) in flatland petrocalcic soils under different land uses
(Elsevier, 2020-03)
Plant-available water (PAW) is one of the most important issues in productive landscapes around the world. Besides climatic conditions, it depends on several factors, among them, land uses, the rooting and water table ...
Water table depth affects persistence and productivity of alfalfa in Central Argentina
(Elsevier, 2019-04)
Alfalfa (Medicago sativa L.) is one of the most sown perennial legumes in the world. Water table depth can be both an opportunity and a threat for this crop. In this study we analyzed 20 years of field experimental data ...
Satellite estimates of euphotic zone and Secchi disk depths in a colored dissolved organic matter-dominated inland water
(Elsevier B.V., 2020-03-01)
The water transparency is an important parameter to water quality monitoring. To quantify the water transparency the attenuation coefficient, k(d), of the photosynthetically active radiation - PAR, k(d)(PAR), the euphotic ...
