Assessing the feasibility of applying remote sensing technique in calculating water consumption

Abstract Remote sensing techniques are currently used in different fields including irrigation and water management fields. One of the important is calculation consumption (WC). can be to estimate actual evapotranspiration it also crop coefficients based on spectral reflectance vegetation indices (VIs), from a relation with normalized difference index (NDVI), which an indicator for absorption reflection ratios by green plant. The current study remote data calculate WC El-Bostan district. Crop coefficient values were calculated NDVI reference using CROPWAT program. obtained results verified comparing them field measurements. There was strong linear correlation between measured r2 0.90, while root-mean-square error (RMSE) 0.68. efficiencies very close each other. illustrated importance reliability calculating values, could improve use efficiency.
