| Abstract/Contents: | "Computer simulations of soil water flow were constructed for a USGA, California, and push-up putting green using HYDRUS-2D. The simulations generated animations of soil water content over a seven-day period for full-size greens having natural surface contours and supporting a closely mown turfgrass stand. Also generated was drainage rate and actual turfgrass evapotranspiration (ETa). Rainfall and evapotranspiration scenarios were selected to challenge the hydrologic response of these three putting greens and a turfgrass response protocol allowed the appraisal of water related turfgrass stress. The simulations demonstrate the utility of deeper rootzone, as seen in the USGA and California greens, in providing a direct connection with subsurface drainage elements and displacing perched water below turfgrass rooting. Alternatively, the shallow rootzone of the push-up green quickly became saturated during rain and remained nearly so for 42 hours, leading to aeration stress of the turf. During rain, the thickness of water perching was self-limited in the USGA green but continued to expand, forming a pattern relative to drainage spacing, in the California green. The simulations show that perched water can form in both USGA and California greens and, in both greens, may serve as a reservoir for subsequent water uptake by the turf. This perched water was, however, locally short-lived in both greens as down slope lateral flow removed it from the crest of steeper slopes within each green. The first appearance of drought stress was associated with the local absence of water perching in both the USGA and California greens, and appeared earlier in the California green due to the lesser water holding capacity of the rootzone." |
