This book was released on 2020 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Improving water quality is a critical societal issue as declines in water quality have been associated with nutrient inputs from land use. Nutrient removal is possible by uptake through biota and soil adsorption. Studies show that nutrient uptake is affected by biotic activity or metabolism, which can be affected by biota type and storm events. As few of these studies involve urban cement-lined streams, the goal of this study is to understand the relationship between nutrient uptake and biotic metabolism while considering the impact that biota type and storm events have in an urban cement-lined stream.I measured nutrient uptake and metabolism in a cement-lined stream in Bloomington, Illinois from June to October 2019. I measured metabolism with dissolved oxygen and photosynthetic light loggers and measured nutrient uptake for ammonia and phosphate (NH4 and PO4-3) with a nutrient addition experiment. In addition, I collected water and algae samples, and examined discharge and storm events. I analyzed water samples in Illinois State University's LEA lab for (NH4 and PO4-3) with an ion chromatograph and a flow injection analyzer, and classified algae as green or blue-green alga based on their genus. Stream metabolism was net heterotrophic with an environmental respiration (ER) of 0.08 - 11.5 g O2/m2/day and gross primary productivity (GPP) of 0.0 - 6.31 g O2/m2/day. The stream was dominated by green algae, which related to increased GPP in the stream. Both ER and GPP decreased after storm events as algae was scoured from the stream bed. However, ER recovered faster than GPP, due to increased microbes and organic matter from upstream. Uptake values for PO4-3 were 1.42 - 6.97 mm/min and 2.71 - 11.6 mm/min for NH4. The relationship of nutrient uptake and metabolism was not significant, and it is assumed that another factor is affecting nutrient uptake. As the cement lining is preventing further nutrient uptake, they may need to be modified to assist in excess nutrient removal in urban zones.
Download or read book Nitrogen and Phosphorus Uptake in an Urban Stream Ecosystem written by Nicolette A. Sheffield and published by . This book was released on 2019 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban stream ecosystems are faced with high input levels of nitrogen (N) and phosphorus (P) from anthropogenic activities. N and P are important to plant growth and stream health; however, high levels can lead to algal blooms and eutrophication, a harmful effect to both aquatic life and water quality. Common urban sources of N and P include fertilizer, atmospheric deposition, stormwater outfall, and leaf-litter decomposition. Common urban stream features such as a flashier hydrograph, altered channel stability and morphology, increase in nutrient output (such as N and P), and heat retention, have been shown to result in an overall decrease in stream biodiversity. High input levels of N are seen within the Mississippi River Basin in the form of nitrate. In urban systems, estimates of loading of N and P into the Mississippi River Basin range from 7-9% for total N and 12-16% for P.This study focused on urban stream nutrient uptake along concrete-lined channels. Tributaries of Sugar Creek in Bloomington-Normal, IL, served as the study area. I hypothesized that concrete-lined channels limit nutrient uptake and maintain higher concentrations of N and P uptake. Measuring nutrient uptake involved short-term N and P additions. Samples tested for nitrate were analyzed on a Dionex ion chromatograph, while samples tested for dissolved reactive phosphate were analyzed following the molybdate method using spectrophotometry. Both N and P uptake velocities measured higher along urban concrete streams as compared to studies conducted in other environments such as deserts and forested areas. In addition, monthly uptake velocities were compared across the study sites, resulting in greater P uptake velocities over N uptake velocities.Many urban streams were modified to manage for hydrology, potentially altering nutrient processing. Thus, quantifying nutrient uptake along a modified streambed will identify how N and P are retained within a stream ecosystem and have implications for stream system restoration.

Book excerpt: This open access book is the first to systematically introduce the principles of urban informatics and its application to every aspect of the city that involves its functioning, control, management, and future planning. It introduces new models and tools being developed to understand and implement these technologies that enable cities to function more efficiently – to become ‘smart’ and ‘sustainable’. The smart city has quickly emerged as computers have become ever smaller to the point where they can be embedded into the very fabric of the city, as well as being central to new ways in which the population can communicate and act. When cities are wired in this way, they have the potential to become sentient and responsive, generating massive streams of ‘big’ data in real time as well as providing immense opportunities for extracting new forms of urban data through crowdsourcing. This book offers a comprehensive review of the methods that form the core of urban informatics from various kinds of urban remote sensing to new approaches to machine learning and statistical modelling. It provides a detailed technical introduction to the wide array of tools information scientists need to develop the key urban analytics that are fundamental to learning about the smart city, and it outlines ways in which these tools can be used to inform design and policy so that cities can become more efficient with a greater concern for environment and equity.
Download or read book Understanding Urban Metabolism written by Nektarios Chrysoulakis and published by Routledge. This book was released on 2014-08-27 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding Urban Metabolism addresses the gap between the bio-physical sciences and urban planning and illustrates the advantages of accounting for urban metabolism issues in urban design decisions. Urban metabolism considers a city as a system, and distinguishes between energy and material flows as its components. Based on research from the BRIDGE project, this book deals with how the urban surface exchanges and transforms energy, water, carbon and pollutants in cities. This book also introduces a new method for evaluating how planning alternatives can modify the physical flows of urban metabolism components and how environmental and socioeconomic components interact. The inclusion of sustainability principles into urban planning provides an opportunity to place the new knowledge provided by bio-physical sciences at the centre of the planning process, but there is a strong need to bridge knowledge and practice, as well as for a better dissemination of research results and exchange of best practice. This book meets that need and provides the reader with the necessary tools to integrate an understanding of urban metabolism into urban planning practice.

Download or read book Biochar for Environmental Management written by Dr. Johannes Lehmann and published by Earthscan. This book was released on 2009 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Biochar is the carbon-rich product when biomass (such as wood, manure, or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process.This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines"--Provided by publisher.

Download or read book Urban Rivers written by Stephane Castonguay and published by University of Pittsburgh Press. This book was released on 2012-05-10 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urban Rivers examines urban interventions on rivers through politics, economics, sanitation systems, technology, and societies; how rivers affected urbanization spatially, in infrastructure, territorial disputes, and in flood plains, and via their changing ecologies. Providing case studies from Vienna to Manitoba, the chapters assemble geographers and historians in a comparative survey of how cities and rivers interact from the seventeenth century to the present. Rising cities and industries were great agents of social and ecological changes, particularly during the nineteenth century, when mass populations and their effluents were introduced to river environments. Accumulated pollution and disease mandated the transfer of wastes away from population centers. In many cases, potable water for cities now had to be drawn from distant sites. These developments required significant infrastructural improvements, creating social conflicts over land jurisdiction and affecting the lives and livelihood of nonurban populations. The effective reach of cities extended and urban space was remade. By the mid-twentieth century, new technologies and specialists emerged to combat the effects of industrialization. Gradually, the health of urban rivers improved. From protoindustrial fisheries, mills, and transportation networks, through industrial hydroelectric plants and sewage systems, to postindustrial reclamation and recreational use, Urban Rivers documents how Western societies dealt with the needs of mass populations while maintaining the viability of their natural resources. The lessons drawn from this study will be particularly relevant to today's emerging urban economies situated along rivers and waterways.
Download or read book Gaseous Carbon Waste Streams Utilization written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-02-22 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the quest to mitigate the buildup of greenhouse gases in Earth's atmosphere, researchers and policymakers have increasingly turned their attention to techniques for capturing greenhouse gases such as carbon dioxide and methane, either from the locations where they are emitted or directly from the atmosphere. Once captured, these gases can be stored or put to use. While both carbon storage and carbon utilization have costs, utilization offers the opportunity to recover some of the cost and even generate economic value. While current carbon utilization projects operate at a relatively small scale, some estimates suggest the market for waste carbon-derived products could grow to hundreds of billions of dollars within a few decades, utilizing several thousand teragrams of waste carbon gases per year. Gaseous Carbon Waste Streams Utilization: Status and Research Needs assesses research and development needs relevant to understanding and improving the commercial viability of waste carbon utilization technologies and defines a research agenda to address key challenges. The report is intended to help inform decision making surrounding the development and deployment of waste carbon utilization technologies under a variety of circumstances, whether motivated by a goal to improve processes for making carbon-based products, to generate revenue, or to achieve environmental goals.

Available in PDF, EPUB and Kindle. Book excerpt: The first-ever book on this subject establishes a rigid, transparent and useful methodology for investigating the material metabolism of anthropogenic systems. Using Material Flow Analysis (MFA), the main sources, flows, stocks, and emissions of man-made and natural materials can be determined. By demonstrating the application of MFA, this book reveals how resources can be conserved and the environment protected within complex systems. The fourteen case studies presented exemplify the potential for MFA to contribute to sustainable materials management. Exercises throughout the book deepen comprehension and expertise. The authors have had success in applying MFA to various fields, and now promote the use of MFA so that future engineers and planners have a common method for solving resource-oriented problems.
