Applicability of using ArcMap to spatiallycalculate and display monthly evapotranspiration rates: An investigation using government climate datain British Columbia, Canada
Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
The methodology of España et al provided a relatively easy way to spatially display algebraic evapotranspiration equations. The results were compared to values of sixteen reference stations, which had been computed by the Penman-Monteith equation. PET values that were interpolated were not as accurate as hoped, however the Hargreaves and Blaney-Criddle methods produced better results than the Thornthwaite method, which resulted in underestimates. Nonetheless, the PET distribution pattern was displayed, and of use to show the areas of highest and lowest rates of PET. In order to produce more accurate values, regional or crop coefficients could be applied to calculate actual evapotranspiration (AET), but time constraints placed on the project restricted the trial of this.
