Download or read book Effect of Urbanization on Base Flow Hydrology Among Ecoregion II Catchments in Eastern United States written by Barry Nolan Blanton and published by . This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Urbanization is a common parameter discussed among hydrologists and its effect on base flow hydrology and the 7Q10 [seven Q ten] statistic varies wildly. Population growth and urban development has grown at an alarming rate in recent years; especially in the Southern and Mid-Atlantic United States. This is due to the fact that 50% of the world’s inhabitants live in cities and over 500 cities house more than 1 million people. Development as it sprawls from urban centers is thought to have negative effects on groundwater recharge and the 7Q10. There are still questions as to how urbanization effects stream base flow. Much focus has been made regarding the use storm water control measures to control peak flows, but literature lacks analysis on the effect of urbanization on stream base flow. This study seeks an understanding of the combined effect or increased urbanization and drainage area size on the 7Q10. This study also examines the effect of reduced forest volumes on watershed hydrology. The aforementioned parameters will be the focus of more in-depth research surrounding the hydrologic responses of 95 catchments in US EPA Eco-Region II. The 95 catchments are a mixture of urban and rural and vary size from 8,815 mi2 [miles squared] to 4 mi2. These catchments are randomly selected inside the relatively large scale homogenous ER2 [eco region two] in an effort to detect trend that may not be visible via small more geographically concentrated studies. The 7Q10 was calculated for each gaging station and related to land cover attribute from the 1992 and 2006 NLCD. Strong correlation was found when relating the 7Q10 to drainage area. Thus, signifying a need to normalize the 7Q10 to drainage area and use this parameter as the response variable for regression. Regression shows a distinct lowering in 7Q10 at the 15-20 % [percent] urbanized situation. This result signifies that an increase in urbanization ultimately reduces the capacity of a watershed to process precipitation and recharge aquifers. The fact that 50-90 % of the true base-flow is from groundwater flow to streams only further proves this hypothesis.

Download or read book Urban Stormwater Management in the United States written by National Research Council and published by National Academies Press. This book was released on 2009-03-17 with total page 611 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid conversion of land to urban and suburban areas has profoundly altered how water flows during and following storm events, putting higher volumes of water and more pollutants into the nation's rivers, lakes, and estuaries. These changes have degraded water quality and habitat in virtually every urban stream system. The Clean Water Act regulatory framework for addressing sewage and industrial wastes is not well suited to the more difficult problem of stormwater discharges. This book calls for an entirely new permitting structure that would put authority and accountability for stormwater discharges at the municipal level. A number of additional actions, such as conserving natural areas, reducing hard surface cover (e.g., roads and parking lots), and retrofitting urban areas with features that hold and treat stormwater, are recommended.

Download or read book Urban Water Cycle Processes and Interactions written by Jiri Marsalek and published by CRC Press. This book was released on 2008-01-07 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Effective management of urban water should be based on a scientific understanding of the impact of human activity on both the urban hydrological cycle – including its processes and interactions – and the environment itself. Such anthropogenic impacts, which vary broadly in time and space, need to be quantified with respect to local climate, urban development, cultural, environmental and religious practices, and other socio-economic factors. Urban Water Cycle Processes and Interactions represents the fruit of a project by UNESCO’s International Hydrological Programme on this topic. The volume begins by introducing the urban water cycle concept and the need for integrated or total management. It then explores in detail the manifold hydrological components of the cycle, the diverse elements of urban infrastructure and water services, and the various effects of urbanization on the environment – from the atmosphere and surface waters to wetlands, soils and groundwater, as well as biodiversity. A concluding series of recommendations for effective urban water management summarize the important findings set forth here. Urban Water Series - UNESCO-IHP Volumes Following from the Sixth Phase of UNESCO’s International Hydrological Programme (2002–2007), the Urban Water Series – UNESCO-IHP addresses fundamental issues related to the role of water in cities and the effects of urbanization on the hydrological cycle and water resources. Focusing on the development of integrated approaches to sustainable urban water management, the Series should inform the work of urban water management practitioners, policy-makers and educators throughout the world.

Download or read book Urban Stormwater written by Victorian Stormwater Committee, and published by CSIRO PUBLISHING. This book was released on 1999-10-28 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: The intense concentration of human activity in urban areas leads to changes in both the quantity and quality of runoff that eventually reaches our streams, lakes, wetlands, estuaries and coasts. The increasing use of impervious surfaces designed to provide smooth and direct pathways for stormwater run-off, has led to greater runoff volumes and flow velocities in urban waterways. Unmanaged, these changes in the quantity and quality of stormwater can result in considerable damage to the environment. Improved environmental performance is needed to ensure that the environmental values and beneficial uses of receiving waters are sustained or enhanced. Urban Stormwater - Best-Practice Environmental Management Guidelines resulted from a collaboration between State government agencies, local government and leading research institutions. The guidelines have been designed to meet the needs of people involved in the planning, design or management of urban land uses or stormwater drainage systems. They provide guidance in ten key areas: *Environmental performance objectives *Stormwater management planning *Land use planning *Water sensitive urban design *Construction site management *Business surveys *Education and awareness *Enforcement *Structural treatment measures *Flow management Engineers and planners within local government, along with consultants to the development industry, should find the guidelines especially useful. Government agencies should also find them helpful in assessing the performance of stormwater managers. While developed specifically for application in Victoria, Australia, the information will be of value to stormwater managers everywhere.

Download or read book Urban Drainage Second Edition written by David Butler and published by CRC Press. This book was released on 2004-05-20 with total page 566 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental and engineering aspects are both involved in the drainage of rainwater and wastewater from areas of human development. Urban Drainage deals comprehensively not only with the design of new systems, but also the analysis and upgrading of existing infrastructure, and the environmental issues involved. Each chapter contains a descriptive overview of the complex issues involved, the basic engineering principles, and analysis for each topic. Extensive examples are used to support and demonstrate the key issues explained in the text. Urban Drainage is an essential text for undergraduates and postgraduate students, lecturers and researchers in water engineering, environmental engineering, public health engineering and engineering hydrology. It is a useful reference for drainage design and operation engineers in the water industry and local authorities, and for consulting engineers. It will also be of interest to students, researchers and practitioners in environmental science, technology, policy and planning, geography and health studies.
