Journal ArticleDOI
Scale dynamics of extensive green roofs: Quantifying the effect of drainage area and rainfall characteristics on observed and modeled green roof hydrologic performance
Raha Hakimdavar,Patricia J. Culligan,Marco Finazzi,Marco Finazzi,Stefano Barontini,Roberto Ranzi +5 more
TL;DR: In this article, the authors examined the effect of green roof drainage area on system performance in an urban climate and found that green roof flooding area has the greatest impact on peak runoff reduction, whereas rainfall retention and the time to peak runoff are not greatly influenced by drainage area.
Journal ArticleDOI
Monitoring Water-Related Ecosystems with Earth Observation Data in Support of Sustainable Development Goal (SDG) 6 Reporting
Raha Hakimdavar,Alfred Hubbard,Frederick Policelli,A. H. Pickens,Matthew C. Hansen,Temilola Fatoyinbo,David Lagomasino,Nima Pahlevan,Sushel Unninayar,Argyro Kavvada,Mark L. Carroll,Brandon I Smith,M. M. Hurwitz,Danielle Wood,Stephanie Schollaert Uz +14 more
TL;DR: The potential for Earth observation (EO) data to support country reporting for SDG Indicator 6.6.1, ‘Change in the extent of water-related ecosystems over time’ is demonstrated and statistical comparisons between different surface water data products can help provide some degree of confidence for countries during their validation process.
Journal ArticleDOI
The Soil Water Apportioning Method (SWAM): An approach for long-term, low-cost monitoring of green roof hydrologic performance
TL;DR: In this paper, a water balance approach termed the Soil Water Apportioning Method (SWAM) was developed to enable economic assessment of the long-term hydrologic performance of green roofs.
Proceedings ArticleDOI
Viability of Recycled and Waste Materials As Green Roof Substrates
TL;DR: In this article, the intrinsic properties of the commercial and recycled substrates, such as unit weight, water retention, leachability and grain size distribution were analyzed to predict the viability of each material to improve green roof performance.
Journal ArticleDOI
Carbon transport in rivers of southwest Haiti
Wade R. McGillis,Diana Y. Hsueh,Yan Zheng,M. Markowitz,Rebecca A. Gibson,G. Bolduc,F.J. Fevrin,J.E. Thys,W. Noel,J. Paine,Zhaohui Aleck Wang,Katherine A. Hoering,Raha Hakimdavar,Patricia J. Culligan +13 more
TL;DR: In this article, the authors measured hydrology and carbon speciation in watersheds of southwest Haiti to quantify the amount of inorganic carbon transport and found that these watersheds have some of the highest DIC and alkalinity reported.
