Upscaling of evapotranspiration fluxes from instantaneous to daytime scales for thermal remote sensing applications [PDF]
Hydrology and Earth System Sciences, 2014 Four upscaling methods for estimating daytime actual evapotranspiration (ET) from single time-of-day snapshots, as commonly retrieved using remote sensing, were compared.

Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract We use the Multiple Element Limitation (MEL) model to examine responses of 12 ecosystems to elevated carbon dioxide (CO2), warming, and 20% decreases or increases in precipitation. Ecosystems respond synergistically to elevated CO2, warming, and decreased precipitation combined because higher water‐use efficiency with elevated CO2 and higher ...

Modeling of hydrological processes in arid agricultural regions [PDF]
Frontiers of Agricultural Science and Engineering, 2015 Understanding of hydrological processes, including consideration of interactions between vegetation growth and water transfer in the root zone, underpins efficient use of water resources in arid-zone agriculture. Water transfers take place in the soil-plant-atmosphere continuum, and include groundwater dynamics, unsaturated zone flow, evaporation ...

Ecological Applications, Volume 32, Issue 8, December 2022., 2022 Abstract Large, citizen‐science species databases are powerful resources for predictive species distribution modeling (SDM), yet they are often subject to sampling bias. Many methods have been proposed to correct for this, but there exists little consensus as to which is most effective, not least because the true value of model predictions is hard to ...

Fen ecohydrologic trajectories in response to groundwater drawdown with an edaphic feedback
Ecohydrology, Volume 15, Issue 8, December 2022., 2022 Abstract Fens are high conservation value ecosystems that depend on consistent discharge of groundwater that saturates the near surface for most of the growing season. Reduced groundwater inputs can result in losses of native diversity, decreases in rare‐species abundance and increased invasion by non‐native species.

Sapwood and heartwood are not isolated compartments: Consequences for isotope ecohydrology
Ecohydrology, Volume 15, Issue 8, December 2022., 2022 Abstract In most tree species, xylem consists of two different functional parts: sapwood and heartwood. While sapwood, as the flowpath for sap, has received more attention in isotope studies assessing water sources accessed by trees (e.g. soil water from different depths, groundwater, stream water or a mixture of these), much remains unknown about ...

Functional traits of riparian trees in the lower Fitzroy River, Western Australia
Ecohydrology, Volume 16, Issue 1, January 2023., 2023 Abstract Riparian trees are critically important for maintaining the ecological function of freshwater ecosystems. Globally, anthropogenic changes to water regimes are impacting the health and distribution of riparian trees. Understanding the physiological constraints on the distribution of riparian tree species in relation to the water regime is ...

Hydrological time series forecasting using simple combinations: Big data testing and investigations on one-year ahead river flow predictability [PDF]
Journal of Hydrology 590 (2020) 125205, 2020 Delivering useful hydrological forecasts is critical for urban and agricultural water management, hydropower generation, flood protection and management, drought mitigation and alleviation, and river basin planning and management, among others. In this work, we present and appraise a new simple and flexible methodology for hydrological time series ...

Perspectives of Hydrologic Modeling in Agricultural Research
, 2021 For decades agricultural research was done in the field or laboratories, but with the rise of computer science, hydrologic modeling became another essential tool for environmental impact studies. Many types of models can be used, each with its strengths and weaknesses in terms of accuracy, speed, and amount of input data needed.
