evaluation of reference evapotranspiration models for a semiarid environment using lysimeter measurements
an accurate determination of evapotranspiration is required for many studies that involve estimation of the water balance. one methodology is the use of lysimeters. considering the semiarid climate of kerman province, in southeastern parts of iran, the only operating electronic weighing lysimeter in the country was used for calculating daily eto from april 2004 to march 2005 in three different ...
متن کاملAdvection Influences on Evapotranspiration of Alfalfa in a Semiarid Climate
Advective enhancement of crop evapotranspiration (ET) occurs when drier, hotter air is transported into the crop by wind, and can be an important factor in the water balance of irrigated crops in a semiarid climate. Thirteen days of moderate to extremely high ET rates of irrigated alfalfa (Medicago sativa L.) were evaluated using energy balance and atmospheric coupling models to examine the mag...
متن کاملNighttime Evapotranspiration from Alfalfa and Cotton in a Semiarid Climate
Nighttime evapotranspiration (ETN) has typically been neglected in estimating water loss from land surfaces. Our objective was to quantify the contribution of ETN to daily (24-h) ET (ET24) of irrigated and dryland cotton (GossypiumhirsutumL.) and irrigated alfalfa (Medicago sativa L.) grown in a semiarid climate. The results were then examined using a Penman–Monteith ETmodel which separates con...
متن کاملevaluation of potential evapotranspiration and pan evaporative methods by lysimeter data in a semiarid climate (case study: qazvin plain)
iran was located in the arid belt and desert region of the world. this climatic situation was presented in several parts of iran such as qazvin. evapotranspiration is one the most important parameter which was effect on agricultural development. there are different methods for estimating this item which selected by climatic conditions. this research concentrates to evaluate 28 empirical and com...
متن کاملEstimation of evapotranspiration using diurnal groundwater level fluctuations: Comparison of different approaches with groundwater lysimeter data
[1] In wetlands or riparian areas, water withdrawal by plants with access to groundwater or the capillary fringe often causes diurnal groundwater fluctuations. Various approaches use the characteristics of these fluctuations for estimation of daily groundwater evapotranspiration rates. The objective of this paper was to review the available methods, compare them with measured evapotranspiration...
