Fig. 15. Sensitivity analysis for the New Mexico site simulation: 25-yr average annual values are shown for the base case simulation and for simulations with a single parameter altered as indicated. PET, potential evapotranspiration; RD, root depth; RLD, root length density; LAI, leaf area index; Ks, saturated hydraulic conductivity; Ku 
, unsaturated hydraulic conductivity function parameter; n, van Genuchten soil water retention function parameter; TX climate, simulation using Texas site climate forcing. Water balance parameters are 
S, water storage change; T, transpiration; E, evaporation; Ro, runoff; D, drainage.
