Restoration activities in the Central Valley of California and elsewhere require accurate evapotranspiration information, which can then be used for a wide variety of surface and subsurface hydrologic evaluations. However, directly measuring evapotranspiration can be difficult or impossible depending on the evaluation’s time frame. Transferability of measured evapotranspiration in time and spac...

Tropical savannas including those of central Brazil (Cerrado) serve as an important regulator of energy and mass exchange with the atmosphere. However, the effects of interactions between grasses and deeply rooted trees and shrubs on energy and water fluxes of savannas are not well understood. In this study, eddy-covariance measurements were used to observe and compare the energy balance and ev...

Land and water resources, climate change, disaster risks significantly affect the agricultural sector. An effective solution for growing crops to improve productivity optimize use of resources is through controlled-environment agriculture (CEA). Evapotranspiration (ET) an important greenhouse crop attribute that can be optimized optimum plant growth. Light intensity radiation are significant co...

Climate change and rapid urbanization could possibly increase the vulnerability of Great Lakes Basin, Canada, which is largest surface freshwater system in world. This study explores joint impact climate land-use changes on hydrology a rapidly urbanizing Credit River watershed lets out into Lake Ontario 25 km southwest downtown Toronto, (ON), Canada; we began by classifying urban rural sections...

Global models projected that, precipitation in Great Plains of the United States will decrease in summer and increase in spring and winter. However, few studies had carefully examined ecosystem responses to this intra-annual redistribution of precipitation. Here we used a process-based model, Terrestrial ECOsystem (TECO) Model, to evaluate responses of ecosystem carbon processes (including net ...

[1] Primary productivity and vegetation cover are strongly related to how precipitation is partitioned into surface discharge, storage, and evapotranspiration (ET). Thus, quantifying feedbacks between changes in precipitation and vegetation at regional scales is a critical step toward predicting both carbon balance and water resources as climate and land cover change. We used a catchment-based ...

Trend analysis and estimation of monthly and annual precipitation, reference evapotranspiration ETo, and rainfall deficit are essential for water-resources management and cropping-system design. Rainfall, ETo, and water-deficit patterns and trends at Macon in eastern Mississippi for a 120-yr period (1894–2014) were analyzed for annual, seasonal, and monthly periods. The analysis showed historic...
