Available in PDF, EPUB and Kindle. Book excerpt: Water plays an essential role in the development and functioning of a city, but could also be a key risk factor for urban pluvial flooding, which may occur more frequently in the context of future climate change. The traditional means of flood risk management relied heavily on engineering measures, or the use of “gray” infrastructure. Recently, there has been a call to integrate nature-based solutions (NBS), which make use of natural processes and ecosystem services, with conventional engineering approaches. NBS infrastructures and designs pay great attention to ecosystem services considerations in assessing their induced hydrological processes, as well as in managing the stormwater and mitigating urban flood and droughts. Nevertheless, compared with grey infrastructure, larger space could be demanded for NBS, while the buffer effect for NBS in extremes events is still uncertain for evaluation.

Abstract: Urbanization replaces once permeable surfaces with relatively impervious ones, thereby degrading the natural hydrologic cycle. Impervious surfaces intensify stormwater runoff in terms of overall mass and temporal response, especially under torrential rainfalls. Since such runoff could become massive in volume and concentrated in time, they place significant stress on the urban drainage system and increase the risks of combined sewage overflow and flooding, which could introduce a range of deleterious consequences to cities and surrounding natural habitats. In sustainable urban stormwater management like the Low Impact Development, green roof presents an on-site source-reduction measure that mimics the pre-development hydrologic functions of storing and gradually releasing precipitation. Green roof can retain and detain stormwater as well as delay and suppress peak discharge. However, green roof stormwater studies have largely been conducted in non-tropical regions of the world. Since green roof's quantitative hydrologic performance can be much influenced by local meteorological conditions, the degree to which such findings can be generalized to other climates, such as Hong Kong's humid subtropical regime, calls for investigation. Moreover, substrate depth has long been regarded as an influential factor in green roof stormwater retention, but two recent studies have provided contradictory results. The objectives of this study are: 1) To evaluate green roof stormwater mitigation performance and potentials in Hong Kong for the first time; 2) To investigate systematically the effect of substrate depth on quantitative hydrologic performance; 3) To identify factors that affect green roof performance; 4) To develop a holistic conceptualization of the various system water storage spaces within a green roof system, for a better understanding of their role in stormwater mitigation. Using small-scale (1.1 m2) raised green roof plots placed on an actual urban rooftop, the effect of 40 mm soil, 40 mm soil + 40 mm rockwool, 80 mm soil, and 80 mm soil + 40 mm rockwool on stormwater mitigation performance relative to control were analyzed. Three core performance indicators (percent retention, peak delay, and peak reduction) were employed to evaluate green roof performance. The results suggest that, while the retention performance of the studied green roofs under Hong Kong's heavy rainfall regime seems to be less effective, remarkable peak reduction and peak delay were observed even when the green roof system has reached full moisture-storage capacity. Such findings are in line with the proposed Green-roof System Capacity model that green roof serves as an effective buffer that regulates water flow through the system. No statistical significance was found between substrate-depth treatments, despite the higher performance across all three indicators for treatment 80. However, satisfactory peak performance of the 40-mm thin substrate suggests that green roof can be applied even on existing buildings that have limited loading capacity. Pertinent meteorological factors were identified. All in all, extensive green roof remains as an effective and promising alternative mitigation strategy to urban stormwater management in Hong Kong with potential application to other tropical areas.

Available in PDF, EPUB and Kindle. Book excerpt: Nineteenth-century landscape architect Frederick Law Olmsted described his most famous project, the design of New York's Central Park, as "a democratic development of highest significance." Over the years, the significance of green in civic life has grown. In twenty-first-century America, not only open space but also other issues of sustainability—such as potable water and carbon footprints—have become crucial elements in the quality of life in the city and surrounding environment. Confronted by a U.S. population that is more than 70 percent urban, growing concern about global warming, rising energy prices, and unabated globalization, today's decision makers must find ways to bring urban life into balance with the Earth in order to sustain the natural, economic, and political environment of the modern city. In Growing Greener Cities, a collection of essays on urban sustainability and environmental issues edited by Eugenie L. Birch and Susan M. Wachter, scholars and practitioners alike promote activities that recognize and conserve nature's ability to sustain urban life. These essays demonstrate how partnerships across professional organizations, businesses, advocacy groups, governments, and individuals themselves can bring green solutions to cities from London to Seattle. Beyond park and recreational spaces, initiatives that fall under the green umbrella range from public transit and infrastructure improvement to aquifer protection and urban agriculture. Growing Greener Cities offers an overview of the urban green movement, case studies in effective policy implementation, and tools for measuring and managing success. Thoroughly illustrated with color graphs, maps, and photographs, Growing Greener Cities provides a panoramic view of urban sustainability and environmental issues for green-minded city planners, policy makers, and citizens.
Download or read book Extensive Green Roofs in Mississippi written by Robert Mack Anders and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Green roofs are increasingly being used in the United States to mitigate the negative effects of impervious surfaces on aquatic ecosystems. Though performance of these systems varies with climate, little research has been conducted in the Southeastern U.S., and no prior research has been conducted in Mississippi. An experiment was conducted to determine the effect of soil depth and roof slope on the stormwater retention of green roofs in Mississippi's hot, humid climate. Simulated roof platforms were constructed to investigate two soil depths and two slopes, each replicated three times and planted with four species of Sedum. The green roof platforms significantly reduced runoff depth when compared with total rainfall depth. Soil depth and slope both significantly affected retention, with higher retention seen with increasing soil depth and lower retention seen with increasing slope. These results indicate that green roofs can be an effective tool to reduce runoff in Mississippi.

Book excerpt: Wissenschaftliche Studie aus dem Jahr 2015 im Fachbereich Landschaftsarchitektur, Landespflege, Gartenbau, , Sprache: Deutsch, Abstract: This paper presents a green roof design where the client requires a specially engineered rooftop that supports plant life, measuring 37m by 44m. They requested a rooftop with a thin layer of low-growing, herbaceous plants that require low maintenance, thus an extensive green roof. The roof had to be a multi-layered build up consisting of a protection fleece layer and a recycled filter fleece under a loose blend of organic and mineral substrate under a planted sedum vegetation. Given the Australian climate, the plants should be densely spaced and able to live in meager soil and also survive exposure to cold, heat, and wind.

Download or read book Evaluating Green Roof Stormwater Management in New York City written by and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In the United States, an aging and overburdened urban infrastructure has become a substantial challenge for civil engineers. Among these challenges, systems for stormwater management are of significant concern, considering their direct impact on environmental quality, local ecosystems, and the hydrologic cycle. Given the high costs for rehabilitation of traditional stormwater infrastructure in urban settings, low impact, or "green" development strategies have become critical components in plans for meeting future stormwater management goals. In particular, New York City (NYC) has pledged $1.5 billion over the next 20 years to improve environmental quality through the mitigation of urban runoff, where utilization of green infrastructure is a primary goal. Cost effective implementation of this, and similar plans around the world, requires comprehensive understanding of green infrastructure functionality. In response, this dissertation investigates the stormwater management potential of full-scale green roofs in NYC through lenses of observation, modeling, and design.

Available in PDF, EPUB and Kindle. Book excerpt: This study evaluates the impact and performance of different green roof systems to manage and control stormwater runoff to prevent watershed pollution over the short and long term in a large urban MSA. A hybrid internet and mail-based stated-preference conjoint choice experiment was administered to residents of the Milwaukee MSA in order to ascertain the public benefits value of green roof infrastructure. This study contributes to the literature on the public benefits of green roofs. The full range of public benefits associated with green roofs, including improved air quality, water quality, biodiversity, and urban heat island effects are estimated. Estimation of all of these public values, allows for determination of the optimal public subsidy for supporting green roofs as a component of decentralized stormwater management in municipalities.
