PPT Slide WRWX ET station PPT Slide PPT Slide PPT Slide PPT Slide PPT Slide Most models use coarse estimates of ET Are coarse estimates of ET "good enough" ? PPT Slide "Foes" of coarse ET estimates Amplification of ET error "Friends" of coarse ET estimates Weekly rain and ET Monthly rain and ET Most variability in atmospheric input is explained by rainfall variability "Friends" of coarse ET estimates PPT Slide "Friends" of coarse ET estimates PPT Slide Simple flow model was effective Simulated flow terms Comparison of several coarse ET estimators Traditional agricultural approach kc = actual ET / PET MODFLOW ET module Heads least sensitive to error in ET when wet Monthly recharge not very sensitive to ET estimator Small ET error _ large cumulative error in recharge Comparison of recharge simulated with coarse ET estimators Important to evaluate utility of coarse estimates of ET in hydrologic analyses
