Abstract/Contents:"Climatological and hydrological models typically ignore anthropogenic irrigation, despite its notable effects on water, energy and biomass conditions. This omission is noteworthy in semiarid cities, such as Phoenix, Arizona, where native and exotic vegetation in urban landscapes are well watered, inducing changes in their phenology and productivity. To our knowledge, the impact of irrigation on urban ecohydrology has yet to be addressed in a quantitative fashion, partially due to a general lack of appropriate soil moisture data from irrigated areas. Thus a rare and valuable opportunity for new avenues of research in urban ecohydrology is presented by the extensive soil moisture data from the North Desert Village neighborhood, funded by CAP-LTER: soil moisture observations have been collected at the site for several years under multiple landscape treatments. This study adapts a point-scale model of the soil water balance and plant stress, utilizing nearby daily records of potential evapotranspiration and rainfall as well as metered irrigation data as model forcing, calibrated using the available soil moisture data. The calibrated model will then be used as a basis to study the sensitivity of soil moisture and plant stress on such factors as soil classification, vegetative cover, meteorological forcing, and irrigation amounts and schedules that are representative of the conditions found in the broader Phoenix metropolitan area. Our results are intended to inform water and landscape managers in making decisions regarding the relationship between water use rates and plant response for different landscape treatments, based on a quantitative model."
