Water use, transpiration and crop coefficients for irrigated hedgerow olives gr...
Santos, Francisco L.; Correia, Maria Manuela; Valverde, Pedro C.; Renato, Coelho; Vaz, Margarida; Paço, T. A.Olive trees are well adapted to the Mediterranean-type agro-ecosystems of southern Portugal and have traditionally been cultivated in areas with no irrigation. According to the 2009 agricultural census, the olive tree cultivation area was around 336,000 ha, of which 164,000 ha are in the southern province of Alentejo. In this southern region of semi arid Mediterranean climate where the erratic annual precipitat...

Santos, Francisco L.; Correia, Maria Manuela; Pôcas, Isabel; Valverde, Pedro C.; Coelho, Renato; Vaz, Margarida; Paço, Teresa A.The use of remote sensing for obtaining evapotranspiration (ET) from natural and agricultural surfaces is already widely used. For irrigated agriculture the two basic approaches are: (1) the solution of the energy balance equation, using remotely sensed surface temperatures and reflectances to estimate variables and components of this equation, and (2) the crop coefficient and reference evapotranspiration (ETo)...
