This book was released on 2016 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The San Luis Valley (SLV)-Taos Plateau study area in south-central Colorado and north-central New Mexico is a large alpine valley surrounded by mountains with an area of approximately 6,263,000 acres (25,345 km2) (Figure ES. 1-1). This area receives ample sunshine throughout the year, making it an ideal location for solar energy generation, and there are currently five photovoltaic facilities operating on private lands in the SLV, ranging in capacity from 1 to 30 megawatt (MW). In 2012 the Bureau of Land Management (BLM) launched its Solar Energy Program, which included the identification of four solar energy zones (SEZs) in the SLV totaling 16,308 acres (66 km2), as well as over 50,000 (202 km2) acres of other BLM-administered lands potentially available for application for solar development. The SEZ areas, named Antonito Southeast, De Tilla Gulch, Fourmile East, and Los Mogotes East, were defined by the BLM as areas well-suited for utility-scale (i.e., larger than 20 MW) production of solar energy where solar energy development would be prioritized (BLM 2012). Nonetheless, it was recognized that solar development in the SEZs would result in some unavoidable adverse impacts, and so the BLM initiated a solar regional mitigation strategy (SRMS) study for three of the SEZs (BLM and Argonne 2016). The SRMS is designed to identify residual impacts of solar development in the SEZs (that is, those that cannot be avoided or minimized onsite), identify those residual impacts that warrant compensatory mitigation when considering the regional status and trends of the resources, identify appropriate regional compensatory mitigation locations and actions to address those residual impacts, and recommend appropriate fees to implement those compensatory mitigation measures.

Download or read book Modeling the Dust Life Cycle and Its Associated Meteorological Processes from Global to Regional Scales written by Lluís Vendrell Miguel and published by . This book was released on 2018 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis aims to test the ability of a non-hydrostatic multiscale mineral dust model to reproduce the physical processes associated with the dust cycle at meteorological scales ranging from synoptic to mesoscale (̃100-1 km spatial resolution) over Northern Africa, the Middle East and Europe (NAMEE). The N03B/BSC-Dust model, the mineral dust module of the N03B-MONARCHv1.0 model, is the main tool used. To reach this objective, three specific modeling studies investigate the model's ability to reproduce mineral dust processes in a wide range of spatial scales. The first study aims to address the consistency of the model in reproducing the dust cycle and its major involved processes, from synoptic to mesoscale (̃100-10 km spatial resolution), for a year (2011) in NAMEE. For that purpose, three model runs are used: one at a global scale and two at the regional scale, which are compared to ground-based observations (weather sites, in-situ PM10 stations and sun-photometers) and aerosol satellite products (MISR and MODIS). The model reproduces the large-scale processes involved in the seasonality of the dust transport in line with MISR and MODIS, and remains consistent between the studied meteorological scales. In comparison with surface observations, the model shows a great ability to resolve long-range dust transport. The model underestimates dust concentrations in the Western and Central Sahara-Sahel in summer, which are associated with wind speed underestimations, low emissions from Mali-Mauritania and omitting haboobs. Otherwise, dust overestimations in the central Sahara-Sahel from October to March are linked to an overestimation of the Harmattan winds. In the Middle East, the model underestimates dust concentrations, which is partly linked to its topography and meteorological small-scale processes that are not well resolved in these configurations. The regional configurations better represented the dust fields' spatiotemporal variability over the region and the finer scales by, for example, enhancing the development of low-level jets and topographic effects on meteorology and dust fields. This analysis demonstrates the model's consistency between global and regional scales. The second study addresses how the model reproduces topographic effects on dust transport over complex topography. For that purpose, two regional model runs (30 and 3 km spatial resolution) covered two synoptic dust storms that occurred on 17-20/03/2012 in the Middle East. In comparison with observations from surface weather stations, sun-photometers, and satellite aerosol products (MODIS and MSG), the model successfully reproduces these dust storms despite differences in the magnitude of the simulated dust fields. Differences between both simulations arise in Southwestern Saudi Arabia, Yemen and Oman where the topography alters the meteorology and the transported dust fields by channeling the dust flow through valleys or by blocking on the windward side of the mountain ranges. In this sense, the dust simulation using a higher horizontal resolution reproduced the dust transport better in the vicinity of complex terrain. The third study investigates the model's ability to resolve haboobs with five model runs at different spatial resolutions and for both parameterized and explicit convection, under a convective situation on 14/07/2011 in West Africa. Parameterized runs are limited in resolving haboobs because they tend to remove atmospheric instability, especially under orographic convective events. This results in an earlier and more abundant rainfall than compared to explicit runs. Haboobs and their associated processes, such as moist convection, cold pools and density currents, are well-developed in the explicit runs at 3 km, but at coarser resolutions (e.g. 10 km) those processes are less intense, and the vertical development of the haboob's front edge is poorly resolved.

Download or read book Modeling Current and Future Windblown Utah Dust Events Using CMAQ 5 3 1 written by Zachary David Lawless and published by . This book was released on 2021 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Windblown dust events can be defined as windblown dust emitted from the Earth's surface to the atmosphere. These events have significant impact on local air quality. Predicting the location and magnitude of these events is vital for Utah air quality assessment and planning. Previous modeling studies have focused only on past dust events. This work utilized a state-of-the-science software framework based on the Community Multiscale Air Quality (CMAQ) v5.3.1 modeling system to predict dust events in Utah. The framework was verified using previous studies for dust events in April 2017 and March 2010. Once verified, the framework was used to predict the impact of future land use properties on dust events. Two scenarios were studied - shrinking of the Great Salt Lake and the addition of large-scale solar farms west of the Wasatch Front. Both showed increases in dust concentrations overpopulated areas using the meteorological conditions from the April 2017 dust event. Such information from future impact studies can assess potential impacts from climate change and can guide government water and land use policies to mitigate dust event impacts.

Download or read book Sustainability of Engineered Rivers In Arid Lands written by Jurgen Schmandt and published by Cambridge University Press. This book was released on 2021-09-16 with total page 305 pages. Available in PDF, EPUB and Kindle. Book excerpt: This interdisciplinary volume examines how nine arid or semi-arid river basins with thriving irrigated agriculture are doing now and how they may change between now and mid-century. The rivers studied are the Colorado, Euphrates-Tigris, Jucar, Limarí, Murray-Darling, Nile, Rio Grande, São Francisco, and Yellow. Engineered dams and distribution networks brought large benefits to farmers and cities, but now the water systems face multiple challenges, above all climate change, reservoir siltation, and decreased water flows. Unchecked, they will see reduced food production and endanger the economic livelihood of basin populations. The authors suggest how to respond to these challenges without loss of food production, drinking water, or environmental health. The analysis of the political, hydrological, and environmental conditions within each basin gives policymakers, engineers, and researchers interested in the water/sustainability nexus a better understanding of engineered rivers in arid lands.

Download or read book Metropolitan Denver written by Andrew R. Goetz and published by University of Pennsylvania Press. This book was released on 2018-09-06 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nestled between the Rocky Mountains to the west and the High Plains to the east, Denver, Colorado, is nicknamed the Mile High City because its official elevation is exactly one mile above sea level. Over the past ten years, it has also been one of the country's fastest-growing metropolitan areas. In Denver's early days, its geographic proximity to the mineral-rich mountains attracted miners, and gold and silver booms and busts played a large role in its economic success. Today, its central location—between the west and east coasts and between major cities of the Midwest—makes it a key node for the distribution of goods and services as well as an optimal site for federal agencies and telecommunications companies. In Metropolitan Denver, Andrew R. Goetz and E. Eric Boschmann show how the city evolved from its origins as a mining town into a cosmopolitan metropolis. They chart the foundations of Denver's recent economic development—from mining and agriculture to energy, defense, and technology—and examine the challenges engendered by a postwar population explosion that led to increasing income inequality and rapid growth in the number of Latino residents. Highlighting the risks and rewards of regional collaboration in municipal governance, Goetz and Boschmann recount public works projects such as the construction of the Denver International Airport and explore the smart growth movement that shifted development from postwar low-density, automobile-based, suburban and exurban sprawl to higher-density, mixed use, transit-oriented urban centers. Because of its proximity to the mountains and generally sunny weather, Denver has a reputation as a very active, outdoor-oriented city and a desirable place to live and work. Metropolitan Denver reveals the purposeful civic decisions made regarding tourism, downtown urban revitalization, and cultural-led economic development that make the city a destination.

Download or read book Lithic Technological Organization and Paleoenvironmental Change written by Erick Robinson and published by Springer. This book was released on 2017-11-06 with total page 344 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this edited volume is to bring together a diverse set of analyses to document how small-scale societies responded to paleoenvironmental change based on the evidence of their lithic technologies. The contributions bring together an international forum for interpreting changes in technological organization - embracing a wide range of time periods, geographic regions and methodological approaches.​ ​As technology brings more refined information on ancient climates, the research on spatial and temporal variability of paleoenvironmental changes. In turn, this has also broadened considerations of the many ways that prehistoric hunter-gatherers may have responded to fluctuations in resource bases. From an archaeological perspective, stone tools and their associated debitage provide clues to understanding these past choices and decisions, and help to further the investigation into how variable human responses may have been. Despite significant advances in the theory and methodology of lithic technological analysis, there have been few attempts to link these developments to paleoenvironmental research on a global scale.

Available in PDF, EPUB and Kindle. Book excerpt: Vernacular architecture represents a great resource that has considerable potential to define principles for sustainable design and contemporary architecture. This publication is the result of an overall aim to produce a valuable tool for analysis regarding vernacular heritage through different assessments, in order to define principles to consider for sustainable development. This was possible through a comprehensive reflection on the principles established and the strategies to recognise in different world contexts. The present publication was the result of an in-depth approach by 46 authors from 12 countries, concerned with the analysis and critical assessment of vernacular heritage and its sustainable perspective. The book presents 8 chapters addressing operational definitions and synopses advances, regarding the main areas of vernacular heritage contribution to sustainable architecture. It also presents 15 chapters and 53 case studies of vernacular and contemporary approaches in all the 5 continents, regarding urban, architectural, technical and constructive strategies and solutions. VERSUS, HERITAGE FOR TOMORROW: Vernacular Knowledge for Sustainable Architecture is the result of a common effort undertaken by the partners ESG | Escola Superior Gallaecia, Portugal, as Project leader; CRAterre | École Nationale Supérieure d’Architecture de Grenoble, France; DIDA | Università degli Studi di Firenze, Italy; DICAAR | Università degli Studi di Cagliari, Italy; and UPV | Universitat Politècnica de València, Spain. This is the final outcome of VerSus, an European project developed from 2012 to 2014, in the framework of the Culture 2007-2013 programme.

Download or read book American Megafaunal Extinctions at the End of the Pleistocene written by Gary Haynes and published by Springer Science & Business Media. This book was released on 2008-12-23 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume contains summaries of facts, theories, and unsolved problems pertaining to the unexplained extinction of dozens of genera of mostly large terrestrial mammals, which occurred ca. 13,000 calendar years ago in North America and about 1,000 years later in South America. Another equally mysterious wave of extinctions affected large Caribbean islands around 5,000 years ago. The coupling of these extinctions with the earliest appearance of human beings has led to the suggestion that foraging humans are to blame, although major climatic shifts were also taking place in the Americas during some of the extinctions. The last published volume with similar (but not identical) themes -- Extinctions in Near Time -- appeared in 1999; since then a great deal of innovative, exciting new research has been done but has not yet been compiled and summarized. Different chapters in this volume provide in-depth resumés of the chronology of the extinctions in North and South America, the possible insights into animal ecology provided by studies of stable isotopes and anatomical/physiological characteristics such as growth increments in mammoth and mastodont tusks, the clues from taphonomic research about large-mammal biology, the applications of dating methods to the extinctions debate, and archeological controversies concerning human hunting of large mammals.
