One of the most important componenets of water management in farms is estimating crops’ exact amount of  evapotranspiration (water need). The FAO-Penman-Montheis (FPM) method is a standard method to evaluate other techniques which are used for easy calculation of potential evapotranspiration, when lysimeter datasheets are not available. This study was carried out based on 18 years’ climatic dat...

in agricultural practices, reference evapotranspiration (et0) parameters need to be specified for crop water requirement determination. although, the crop water requirement is not an easy task. numerous mathematical models and experimental methods have been developed for this purpose in the entire world. on the other hand, ten-daily and monthly average meteorological data are used in many of ir...

By delivering monthly maps of the gravity field, the GRACE project allows the determination of tiny time-variations of the Earth gravity and particularly the effects of fluid mass redistributions at the surface of the Earth. However, GRACE data represent vertically integrated gravity measurements, thus are the sum of all mass redistributions inside the Earth system (atmosphere, oceans and conti...

Evapotranspiration (ET) from the wetland of the Yellow River Delta (YRD) is one of the important components in the water cycle, which represents the water consumption by the plants and evaporation from the water and the non-vegetated surfaces. Reliable estimates of the total evapotranspiration from the wetland is useful information both for understanding the hydrological process and for water m...

This study investigated the effects of climate change on the evapotranspiration amount and water balance in the Zayandeh-Rud river basin. Two important weather stations; Isfahan and Chelgerd stations, located in the East and West of the basin respectively, were selected for investigation in this study. The combination of 15 GCM models were created based on the weighting method and three pattern...

ABSTRACT-Different evapotranspiration (ET) estimation equations having different accuracy with different conditions have been developed for ET estimation. This study will firstly focus on the estimation of 13 climatic equations of daily garlic ET estimation whose  ET is measured by lysimeter to provide information which can be helpful in selecting an appropriate ET equation. The paper aims at s...

-Evapotranspiration experts often need to make decisions relating to the precision of the results of various existing methods such as traditional and satellite methods. For these reasons a decision support system (EVA) is developed in order to provide evapotranspiration experts with a tool for evaluating the results of a variety of existing methods for estimating potential and real evapotranspi...

Supplemental Methods. Library preparation and semiconductor sequencing. For screening of the three PMBL cell lines we employed a multiplex PCR based Ion Torrent AmpliSeqTM cancer panel (Life Technologies) covering approx. 2,800 COSMIC annotated mutations in 50 key cancer genes (Supplemental Table 1). Amplicon library preparation was performed using ~10ng of DNA as advised by the manufacturer. B...
