the anatomical and epidermal characteristics, as well as the physiological response, of 'colombia' ecotype cape gooseberry plants treated or untreated with foliar applications of kaolin at 2 irrigation levels (well-irrigated plants vs. water-stressed plants) were evaluated. relative water content (rwc), stomatal density, and chlorophyll index were reduced under water stress. water stress increa...

Soil organic carbon (SOC) content and the water holding capacity of soils are two properties which link hydrological cycles. Hydrological model inputs seldom include soil as a parameter even though is known to influence retention capacities. This study sensitivity analysis changes in responses when different percentages for topsoil horizon. Sensitivities such transpiration, runoff volumes, stor...

Transpiration, as one of the components of hydrological cycle, has not been paid enough attention yet, while it is necessary for sound utilization of rangelands, mostly located in the arid and semiarid regions. The comparison of the different kinds of rangelands species in terms of transpiration rates provides range managers the required information to achieve optimal forage production for a gi...

Transpiration of a mixed spruce-aspen-birch forest at the Valday Hills in Russia was determined using sap fl ow measurements and two different SVAT (Soil–Vegetation–Atmosphere-Transfer) models. The more sophisticated Mixed Forest multi-layer SVAT model (MF-SVAT) considers water uptake and transpiration of each tree species individually, and the simple Multi-Layer (ML-SVAT) describes the forest ...

A small proportion of water molecules contain the heavier isotopes of hydrogen and oxygen. There is a tendency for these heavier molecules of water to accumulate in leaves during transpiration. This has several interesting repercussions, including effects on the isotopic composition of organic matter, and of atmospheric water vapor, carbon dioxide, and oxygen. In turn, these effects aid tempora...

[1] A Bayesian approach was used to fit a conceptual transpiration model to half-hourly transpiration rates for a sugar maple (Acer saccharum) stand collected over a 5-month period and probabilistically estimate its parameter and prediction uncertainties. The model used the Penman-Monteith equation with the Jarvis model for canopy conductance. This deterministic model was extended by adding a n...

• New OP variant with service time dependent profits and travel times. Mathematical formulation possible applications of this problem. Metaheuristic solution approach composed specific local moves. Benchmark instances known optimal solutions to verify the approach. Real data instance evaluate proposed model method. This paper addresses orienteering problem windows (TDOPTW-STP). In TDOPTW-STP, e...

estimation of evapo-transpiration is necessary in cases such as irrigation planning, determining of evaporation of the water bodies, water balance assessment, estimation of runoff and watershed management and ecological and meteorological studies. evapo-transpiration can be determined precisely using field measurements. however, these methods provide evapo-transpiration just for limited areas f...
