Recent evidence from leaves and stems indicates that gradients in water potential (psi(w)) necessary for water movement through growing tissues are larger than previously assumed. Because growth is sensitive to tissue psi(w) and the behavior of these gradients has not been investigated in transpiring plants, we examined the water status of all the growing and mature vegetative tissues of maize ...

Nighttime transpiration is a substantial portion of ecosystem water budgets, but few studies compare water use of closely related co-occurring species in a phylogenetic context. Nighttime transpiration can range up to 69% of daytime rates and vary between species, ecosystem, and functional type. We examined leaf-level daytime and nighttime gas exchange of five species of the genus Rubus co-occu...

This paper is an attempt to assess the potential and usefulness of ANN based modeling for evaporation prediction from a reservoir, where in classical and empirical equations failed to predict the evaporation accurately. The meteorological data set of daily pan evaporation, temperature, solar radiation, relative humidity, wind speed is used in this study. The performance of feed forward back pro...

The e€ects of landscape changes on winter and spring snow-related processes, and on regional weather and climate are not thoroughly understood. In this study, a climate version of the Regional Atmospheric Modelling System (ClimRAMS) is used to investigate the e€ects of landscape change on seasonal snow depletion and its corresponding e€ects on atmospheric and hydrologic processes. Two simulatio...

Evapotranspiration (ET), which is a combination of the words evaporation and transpiration, expressed as sum water due to consumption in plants. In this study, NASA Drought Early Warning Systems Network Land Data Assimilation System model (FLDAS NOAH) was used determine evapotranspiration data for 2018-2019 years (October 2017-September 2019) on Turkey. addition, Global (GLDAS temperature data....

The effect of restricted xvater supply or drought periods on transpiration after rewatering the plants has been investigated repeatedly (3, 4, 5, 9, 11, 16). It has been found that, after a periodl of recovery, changes in the transpiration rate in plants grown under restricted water supply relative to those in plants not subjected to water stress may occur. The recorded rates, however, vary wid...

Present-day land surface schemes used in weather prediction and climate models include parameterizations of physical processes whose complex nonlinear interactions can lead to models of unknown spatial and temporal characteristics. This paper describes the timescales of the evapotranspiration response of 16 land surface schemes which participated in the Project for Intercomparison of Land-surfa...

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/transpiration from vegetated/ bare soil and surf...

Evapotranspiration (ET) is a crucial process in the terrestrial water cycle, and understanding its stable isotopic evolution essential for comprehending hydrological processes. The Craig–Gordon (C-G) model widely used to describe fractionation during pure evaporation. However, natural environments, ET involves both transpiration (T) evaporation (E), traditional C-G does not account effect of on...
