Developing Climate Resilience in Aridlands Using Rock Detention Structures as Green Infrastructure

The potential of ecological restoration and green infrastructure has been long suggested in the literature as adaptation strategies for a changing climate, with an emphasis on revegetation and, more recently, carbon sequestration stormwater management. Tree planting “natural” detention structures such bioswales, basins, sediment traps are popular approaches. However, experimental verification performance these investments is scarce does not address rock specifically. This 3-year study investigates infiltration, peak flow mitigation, microclimate natural wash retention installation using one-rock dams urban park Phoenix, Arizona, USA. Field data collected during do depict change hydrogeomorphology. hydrologic modeling, from field, portrays decreases flows increases infiltration at treated sites. Additionally, we observe lengthening cooling effects following rainfall events, compared untreated In this arid land setting, prospect that themselves could reduce warming or heat promising.
