Abstract/Contents:Presents a study conducted to "(a) experimentally measure protential evapotranspiration in an urban setting; and (b) calibrate the Blaney-Criddle formula, as presented by Criddle et al. (1962) and the SCS (1967), for bluegrass turf." Details the materials and methods used in the study, stating that "evapotranspiration rates of lawn grass were measrued in Laramie and Wheatland, Wyoming, during the summers of 1976 and 1977...Measured Etp [potential evapotranspiration] rates were intended to approximate the average city-wide values which could be expected to occur if adequate water were applied and if al other factors, such as fertilization and general maintenance habits, remained unaltered." Discusses the Blaney-Criddle formula, stating that "the Blaney-Criddle method is one of the most popular for seasonal and monthly evapotranspiration estimates and is also the method generally used in court cases transferring water rights from agricultural to municipal usages." States that "to calibrate the formula, lawn grass consumptive use curves were developed. These curves are specifically for Kentucky bluegrass and the bluegrass-fescue grass types grown in an urban setting." Reports that "Criddle's curve define consumptive use coefficients that have larger values for correspondingly higher seasonal consumptive use factors. This was not found to be the case for the lawn grasses tested." Concludes that "the calibrated equations should provide improved estimates of Etp rates suitable for most engineering uses."
