Course Description
Landscape water budgets are central to many urban development programs, green building codes, and conservation programs of water purveyors. These programs and regulations require various approaches to calculate and establish a site’s a water-conserving irrigation budget and irrigation schedules based in part on estimated local reference evapotranspiration (ETo) data. The calculations typically involve an assortment of ETo adjustment factors associated with plant species, site characteristics, or other influences on how much water a landscape should be allocated. Depending on the program or policy, the adjustments to ETo may be fixed, variable, or some combination. Research on the water needs of landscape plants provides insight on which ETo adjustment factors make sense to apply and how values for them can be accurately estimated. An analysis of commonly used approaches for estimating landscape water budgets will be presented along with research-based ETo adjustment factors that should be employed in them.
