Book excerpt: As our urban areas grow, so too do these unintended hydrologic consequences of both urban development and traditional stormwater management systems. To combat these issues, cities are increasingly turning to stormwater management practices that better mimic natural hydrology by capturing, infiltrating, or evapotranspiring water in a distributed fashion throughout the watershed. These low impact development (LID) practices have proven effective at locally altering the water balance, but quantitative performance can vary widely across studies and it can be difficult to untangle which site-specific characteristics (e.g., climate, soil, vegetation, microtopography, impervious connectivity) are the most important drivers of observed differences in hydrologic behavior. In order to increase the adoption and reliability of LID, there is a continued need to improve our scientific understanding of how site-specific characteristics affect urban hydrologic processes and the performance of LID practices. In this dissertation, I use a physically-based hydrologic model, ParFlow.CLM, to simulate surface and subsurface hydrology at a high (0.5m) spatial resolution on single-family parcels and explore the effects of LID practices on parcel-scale runoff, deep drainage, and evapotranspiration. First, I examine how three "impervious-centric" practices (disconnecting downspouts, disconnecting sidewalks, and adding a transverse slope to the driveway and front walk), two "pervious-centric" practices (decompacting soil and adding microtopography), and all possible "holistic" combinations affect parcel-scale hydrology. Second, I systematically explore how climate moderates the effects of these LID practices on the water balance by forcing a baseline parcel with no LID practices and a parcel with all five LID practices with one year of hourly meteorological records from the 50 largest U.S. cities plus Madison, WI. Third, I more closely examine the potential of soil amendment as a LID practice by comparing targeting soil amendment a) disconnected impervious features, b) by drainage area, c) by topographic wetness index (TWI), and d) randomly. Lastly, I determine which attributes of residential single-family parcels best predict changes in hydrologic fluxes due to infiltration-based LID practices by 1) developing a suite of typical single-family lot layouts based on property assessor data for tax parcels in Madison, WI, 2) simulating baseline and low impact versions of these lots using ParFlow.CLM, and 3) building statistical models that relate single-family lot attributes to changes in runoff and deep drainage. This research demonstrates the crucial role of impervious-pervious interfaces on urban hydrology. While these sub-parcel features are rarely captured in urban hydrologic models, they have the potential to substantially alter the urban hydrologic water balance. LID interventions which both disconnect impervious surfaces and increase the infiltration capacity of soil adjacent to these features can efficiently and effectively alter the water balance at the parcel scale. The degree of hydrologic change possible from these LID practices is largely driven by the size of all impervious surfaces, the size of the house, and the size of the street plus alley; lot attributes which can be easily identified by water resources managers as a "first-cut" for determining where to encourage LID practices on private property. When evaluating which types of LID practices to promote, it is critical to consider climate characteristics like the aridity index and, to a lesser extent, rainfall intensity and the relative timing of energy and water availability. Overall, this research offers new insights into how site-specific, subparcel characteristics interact to affect larger-scale urban hydrologic processes.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This unique sourcebook provides a global, state-of-the-art review of the rapidly evolving field of strategic environmental assessment (SEA) that is intended to serve as a baseline for the work of an OECD Task Team on SEA and a UNEP initiative on integrated planning and assessment. It describes trends in application and experience in different contexts worldwide, providing in-depth coverage of the status of SEA systems, and practice in developed, transitional and developing countries by a range of development agencies. The book draws on a large body of published and unpublished material, and contributions from a wide range of individual experts, organizations and agencies. It provides an unparalleled and invaluable understanding of the emerging scope and potential of SEA and describes how, when and where it is being used. The sourcebook includes a probing review of concepts, terminology, approaches and tools of SEA, and a comparative analysis of the different types of existing SEA systems. The volume also contains many case examples illustrating SEA practice in different countries and contexts, a full set of references and a number of appendices containing source materials.

Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of three symposia of the Dutch Society for Landscape Ecology (Werkgemeenschap voor Landschapsecologisch Onderzoek) about • the Dutch National Ecological Network • urban ecology • and civil infrastructure. The three topics - among others - show important contexts in which landscape ecologists do their research and apply their knowledge and skills. The book focuses on urbanisation, intensive land use and water management as characteristic features of the Netherlands and therefore presents an important view on landscape ecology in the Dutch context.

Available in PDF, EPUB and Kindle. Book excerpt: This book is open access under a CC BY-NC 4.0 license. This revised, updated textbook presents a systems approach to the planning, management, and operation of water resources infrastructure in the environment. Previously published in 2005 by UNESCO and Deltares (Delft Hydraulics at the time), this new edition, written again with contributions from Jery R. Stedinger, Jozef P. M. Dijkman, and Monique T. Villars, is aimed equally at students and professionals. It introduces readers to the concept of viewing issues involving water resources as a system of multiple interacting components and scales. It offers guidelines for initiating and carrying out water resource system planning and management projects. It introduces alternative optimization, simulation, and statistical methods useful for project identification, design, siting, operation and evaluation and for studying post-planning issues. The authors cover both basin-wide and urban water issues and present ways of identifying and evaluating alternatives for addressing multiple-purpose and multi-objective water quantity and quality management challenges. Reinforced with cases studies, exercises, and media supplements throughout, the text is ideal for upper-level undergraduate and graduate courses in water resource planning and management as well as for practicing planners and engineers in the field.
