| Abstract/Contents: | "Hydraulic property criteria suggested by the U.S. Golf Association (USGA) Green Section are used to select construction materials for golf putting greens, but measurement of these hydraulic properties is difficult and results are highly variable. This is particularly true in the case of the saturated hydraulic conductivity, Ksat. An alternative to direct measurement of hydraulic properties is their prediction using other measured predictor variable(s) such as soil water retention properties and particle size distribution data. A power-law model of Ksat was modified to derive all needed parameters from the inflection point of a s-shaped soil water retention function. The proposed model has been successfully used to predict textural averages of Ksat, but it has not been tested on individual samples. The objective of this study was to apply the model to the prediction of Ksat values of root zone mixes. Four datasets containing laboratory measurements of Ksat and water retention curves covering a range of textural compositions and levels of compaction were analyzed. The model successfully predicted Ksat for the four data sets. The linear relationship between predicted and measured Ksat was significant at P>0.95. Furthermore, significant correlations were found between the water retention derived parameters of the Ksat model and parameters characterizing particle size distributions of the mixes. This result suggests that in the absence of water retention information, Ksat could be predicted from particle size data. The proposed model could be used to improve the design, construction and management of golf courses." |
