“…These outcomes were developed with the City of Phoenix Parks and Recreation Department and summarized in ways that highlighted the co‐benefits for green waste compost applications with changes in irrigation management. Additional observations in urban areas (e.g., Alizadehtazi et al, 2020; Gomez‐Navarro et al, 2019; Vivoni et al, 2020) would certainly help elucidate further the fate of irrigation and other water sources. Furthermore, the incorporation of these findings in regional simulations (e.g., Reyes et al, 2018; Bohn et al, 2018; Wang, Vivoni, et al, 2021) would allow an assessment of the water savings potential at the city or metropolitan area scale.…”

Water conservation potential of modified turf grass irrigation in urban parks of Phoenix, Arizona

Large amounts of water are consumed by urban parks in arid regions such that efficient irrigation practices are needed. In Phoenix, Arizona, extensive turf grass areas are supported using flood or sprinkler irrigation that also require fertilizers. Residential green waste compost has the potential to serve an alternative fertilizer if its higher costs can be offset through water conservation. In this study, we conducted an ecohydrological monitoring and modelling effort for a compost experiment in two urban parks with either flood or sprinkler irrigation. Soil moisture, evapotranspiration and turf greenness data along with a soil water balance model were used to determine if compost treated plots were different from control plots in each park. After building confidence in the model through comparisons to data, we created long‐term scenarios to explore differences between flood and sprinkler irrigation practices and analyse the effect of changes in irrigation scheduling. Multiple lines of evidence indicated that green waste compost applications did not appreciably change soil moisture or vegetation conditions in either urban park. Major differences, however, were noted between the two irrigation practices in terms of the seasonality of the soil water balance, plant water stress and the sensitivity to interannual fluctuations in precipitation. Model scenarios showed that significant irrigation reductions from 15% to 30% could be achieved, in particular with small changes in watering depths. As a result, irrigation management in urban parks can meet water conservation targets that potentially offset green waste compost costs while also benefitting the soil water balance through reductions in water losses.

In order to build a scientific and reasonable urban park green infrastructure network. Genetic Tabu hybrid algorithm is introduced into the field of urban park green infrastructure network construction, using ENVI5.5, ArcGIS10.2, Conefor2.6, and other software to construct the comprehensive green infrastructure network model and corresponding algorithm of a city park and improve and compare the genetic algorithm and Tabu search algorithm. Firstly, the ecological sensitivity of urban parks was evaluated, and 58 ecological source patches with high ecological value were selected. With the help of GIS platform, 71 potential corridors are simulated and generated by using the minimum cost path model. Then, select the index that can evaluate the importance of source patches in the ecological network to determine the importance ranking of source patches. Finally, according to the principles of clustering and network connectivity, select the ecological source with high patch importance, analyze the potential ecological corridor and current corridor, and combine and screen the factors of green infrastructure network. The results show that a city park green infrastructure network composed of 38 ecological source patches and 19 corridors is finally formed. Genetic algorithm has a potential application prospect in the construction of urban park green infrastructure network. By introducing genetic Tabu hybrid algorithm into the field of urban park green infrastructure network construction, it will change the mode of traditional urban park green infrastructure network construction.

“…Design features included the GI's location, surface area, drainage area, storage volume, soil media depth, age, and drainage area to surface area ratio (DA/SA ratio). The DA/SA ratio, also known as the hydraulic loading ratio, 48,49 was calculated by dividing the drainage area by the surface area. Since we cannot explicitly calculate inflow without highly localized measurements of precipitation, which were unavailable, this quantity is used to capture the relative amount of inflow to each GI.…”
