Download or read book Hydro Environmental Analysis written by James L. Martin and published by CRC Press. This book was released on 2013-12-04 with total page 5742 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on fundamental principles, Hydro-Environmental Analysis: Freshwater Environments presents in-depth information about freshwater environments and how they are influenced by regulation. It provides a holistic approach, exploring the factors that impact water quality and quantity, and the regulations, policy and management methods that are necessary to maintain this vital resource. It offers a historical viewpoint as well as an overview and foundation of the physical, chemical, and biological characteristics affecting the management of freshwater environments. The book concentrates on broad and general concepts, providing an interdisciplinary foundation. The author covers the methods of measurement and classification; chemical, physical, and biological characteristics; indicators of ecological health; and management and restoration. He also considers common indicators of environmental health; characteristics and operations of regulatory control structures; applicable laws and regulations; and restoration methods. The text delves into rivers and streams in the first half and lakes and reservoirs in the second half. Each section centers on the characteristics of those systems and methods of classification, and then moves on to discuss the physical, chemical, and biological characteristics of each. In the section on lakes and reservoirs, it examines the characteristics and operations of regulatory structures, and presents the methods commonly used to assess the environmental health or integrity of these water bodies. It also introduces considerations for restoration, and presents two unique aquatic environments: wetlands and reservoir tailwaters. Written from an engineering perspective, the book is an ideal introduction to the aquatic and limnological sciences for students of environmental science, as well as students of environmental engineering. It also serves as a reference for engineers and scientists involved in the management, regulation, or restoration of freshwater environments.

Available in PDF, EPUB and Kindle. Book excerpt: Transportation asset management delivers efficient and cost-effective investment decisions to support transportation infrastructure and system usage performance measured in economic, social, health, and environmental terms. It can be applied at national, state, and local levels. This distinctive book addresses asset management for multimodal transportation, taking account of system component interdependency, integration, and risk and uncertainty. It sets out rigorous quantitative and qualitative methods for addressing system goals, performance measures, and needs; data collection and management; performance modeling; project evaluation, selection, and trade-off analysis; innovative financing; and institutional issues. It applies as easily to static traffic and time-dependent or dynamic traffic which exists on a more local level. It is written for transportation planners, engineers, and academia, as well as a growing number of graduate students taking transportation asset management courses.

Download or read book A Methodology for Highway Asset Valuation in Indiana written by Michelle S. Dojutrek and published by Joint Transportation Research Program. This book was released on 2012-12-31 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Government Accounting Standards Board (GASB) requires transportation agencies to report the values of their tangible assets. The shortcomings of traditional valuation methods include the implicit monolithic assumption of asset structures and the parochial range of value-related asset attributes considered in the evaluation process. Thus, this research developed enhanced methods and concepts for valuation. The elemental decomposition and multi-criteria (EDMC) method uses asset component costs, remaining service lives and condition. The replacement-downtime-salvage method considers life-cycle costs, including workzone user costs, and recycling benefits or disposal costs. The decommission-and-reuse method is based on the real-estate value of land occupied by the asset. The probabilistic method considers the asset value as a function of its survival likelihood. This study determined the total value of Indiana's state highway assets using traditional and proposed methods and new considerations. For the proposed EDMC method, this estimate was $45 billion. The value of pavements and bridges were $37.38B and $3.40B, respectively, together constituting 90% of total asset value. The total value of smaller assets (guardrails, underdrains, culverts, and road signs) was approximately $1.2B, and rights-of-way, $2.840B, constituting approximately 3% and 7%, respectively of the total asset value. On the basis of the unit asset values derived for Indiana, the existing asset inventory of other states, and the state-specific cost factors, the total estimated value of state-owned and overall highway bridge and pavement assets in the United States was estimated at $3.4T and $16.2T, respectively, using EDMC, and $2.9T and 13.8T, respectively, using GASB 34. The study also explored ways in which asset value could be incorporated in investment evaluation.

Book excerpt: This report present a process for quantifying the consequences of delayed maintenance of highway assets that considers the asset preservation policy, the maintenance and budget needs, and the analysis of delayed maintenance scenarios. This process considers delayed maintenance caused by the inability to meet the agency-defined application schedule or the unavailability of the funds required to perform all needed maintenance, and expresses the consequences in terms of asset condition and the costs to owners and road users.

This book was released on 2013 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Roadway infrastructure within the United States includes features such as roads, bridges, signs, pavement markings, traffic signals, support commerce and mobility, and is, in essence, a shared financial public resource worthy of being managed at the highest level of efficiency. State departments of transportation (DOTs), local transportation authorities, and federal agencies responsible for the fiscal management of the transportation system have shown a growing interest in advancing the state of practice in managing these critical assets. In addition, the recent congressional passage of Moving Ahead for Progress in the 21st Century Act (MAP-21 Act) has established an outcome-driven, performance-tracking approach that will hold states and metropolitan planning organizations accountable for improving the conditions and performance of their transportation assets. It will therefore increase agency attentiveness to these vital issues. Transportation Asset Management (AM) is a strategic and systematic process of operating, maintaining, upgrading, and expanding physical assets effectively throughout their life cycle. It focuses on business and engineering practices for resource allocation and utilization, with the objective of better decision making based on quality information and well-defined objectives. Advancing AM capabilities and integrating these capabilities across an organization's business units requires self-assessment, alignment, goal setting, and support. This synthesis of transportation asset management practice among state highway agencies will be a timely resource for agencies to identify their current state of practice and determine where they will direct their AM efforts. This synthesis is based on two separate surveys, with additional input from practitioners. The initial survey requested that participants conduct a self-assessment to characterize their agency's AM practices....The self-assessment results reflect current and future (5-year) business practices and the agencies' institutional, organizational, financial, and IT environments. This survey yielded 18 DOT participant responses (see Appendix D). Based on the results of the initial survey, and input from the Topic Panel, a second survey was designed to capture the state of practice and forward looking expectations (for the next 3 to 5 years) among state DOTs. Forty-three agencies participated in this second survey."--p. 1.
