Estimation 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...
متن کاملComparison of seven models for estimation of evapotranspiration and groundwater recharge using lysimeter measurement data in Germany
This study evaluates seven evapotranspiration models and their performance in water balance studies by using lysimeter measurement data at the Mönchengladbach hydrological and meteorological station in Germany. Of the seven evapotranspiration models evaluated, three models calculate actual evapotranspiration directly using the complementary relationship approach, i.e. the CRAE model of Morton, ...
متن کاملEvaluation of Sensible Heat Flux and Evapotranspiration Estimates Using a Surface Layer Scintillometer and a Large Weighing Lysimeter
Accurate estimates of actual crop evapotranspiration (ET) are important for optimal irrigation water management, especially in arid and semi-arid regions. Common ET sensing methods include Bowen Ratio, Eddy Covariance (EC), and scintillometers. Large weighing lysimeters are considered the ultimate standard for measurement of ET, however, they are expensive to install and maintain. Although EC a...
متن کاملEstimated evapotranspiration of rice based on pan evaporation as a surrogate to lysimeter measurement
Reference crop evapotranspiration (ET o), used to determine actual crop evapotranspiration, is often estimated from pan evaporation (EP) data. However, uncertainties in the relationship between ET o and EP often result in unreliable estimate of crop evapotranspiration. This study investigated the relationship between measured and estimated crop evapotranspirations, ET m and ET e, respectively, ...
متن کاملevaluation 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 ...
