  abstract = {{O}lives constitute a frequently grown crop in semi-arid areas. {T}herefore, accurate quantification of evapotranspiration ({ET}) within olive groves is crucial to enhance agricultural water productivity and promote their resilience to water scarcity and future climate scenarios. {I}n the present work, we assessed the accuracy of 3 versions of the {T}wo-{S}ource-{E}nergy-{B}alance ({TSEB}) model, the first one {TSEB}-{SPT} using a standard {P}riestley-{T}aylor coefficient (alpha {PT}) to estimate the transpiration, the second one called '{TSEB}-{CPT}' constrained by a computed alpha{PT} using measured {ET} along with the equilibrium term, and the third one {TSEB}-{SM} where soil moisture is used as an additional constraint to improve the soil evaporation. {T}he 3 models were applied over an irrigated olive orchard in the {T}ensift basin ({M}orocco) during two growing periods of 2003 and 2004. {T}he comparison with ground-based flux measurements from {E}ddy-{C}ovariance tower and sap flow data revealed that the {TSEB}-{SPT} model overestimates {ET} with an average relative error of 87% and a percentage bias of -78% during the two growing seasons. {C}onversely, {TSEB}-{SM} and {TSEB}-{CPT} improved {ET} estimates as compared to {TSEB}-{SPT}, with mean relative errors of 31% and 24% and an average percentage bias of 0.6% and -7.4%, respectively. {F}or {ET} partitioning, {TSEB}-{SM} appears to be less effective in estimating transpiration, while the simulated transpiration by {TSEB}-{CPT} fits well the actual one with a root mean square error of 0.27 mm, mainly during the summer of 2003. {T}hese results open a path for future improvements: by reviewing the calibration procedure of ?{PT}, and implementing alternative formulas to compute the evaporation, the {TSEB}-{SM} could be potentially a robust tool for monitoring the seasonal variation of {ET} and its partitioning over a heterogeneous canopy cover.},
