Abstract
Estimation of urban outdoor water demand is challenging due to variability in the irrigation of heterogeneous vegetated surfaces. Urban shade can cause fluctuations in irrigation water demand due to changes in air temperature subsequently affecting evapotranspiration (ET). This study analyzes the effect of urban shade on landscape ET. The shade is quantified using the sky view factor (SVF) whereas ET data from the Earth Engine Evapotranspiration Flux (EEFLUX) database is used. This analysis is done for May 2018 month that corresponds to hot season. A small region in Las Vegas Valley having varied land cover types is chosen for this analysis. This research reveals that the presence of shade decreases ET, potentially due to the decrease in air temperature and direct solar radiation. This study is insightful in understanding the effect of shade on irrigation water demand due to the presence of buildings.
