Download or read book Water quality characteristics trends and nutrient and sediment loads of streams in the Treyburn development area North Carolina 1988 2009 written by Jason M. Fine and published by CreateSpace. This book was released on 2013 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Streamflow and water-quality data, including concentrations of nutrients, metals, and pesticides, were collected from October 1988 through September 2009 at six sites in the Treyburn development study area. A review of water-quality data for streams in and near a 5,400-acre planned, mixed-use development in the Falls Lake watershed in the upper Neuse River Basin of North Carolina indicated only small-scale changes in water quality since the previous assessment of data collected from 1988 to 1998. Loads and yields were estimated for sediment and nutrients, and temporal trends were assessed for specific conductance, pH, and concentrations of dissolved oxygen, suspended sediment, and nutrients. Water-quality conditions for the Little River tributary and Mountain Creek may reflect development within these basins. The nitrogen and phosphorus concentrations at the Treyburn sites are low compared to sites nationally. The herbicides atrazine, metolachlor, prometon, and simazine were detected frequently at Mountain Creek and Little River tributary but concentrations are low compared to sites nationally. Little River tributary had the lowest median suspended-sediment yield over the 1988–2009 study period, whereas Flat River tributary had the largest median yield. The yields estimated for suspended sediment and nutrients were low compared to yields estimated for other basins in the Southeastern United States. Recent increasing trends were detected in total nitrogen concentration and suspended-sediment concentrations for Mountain Creek, and an increasing trend was detected in specific conductance for Little River tributary. Decreasing trends were detected in dissolved nitrite plus nitrate nitrogen, total ammonia plus organic nitrogen, sediment, and specific conductance for Flat River tributary.

Download or read book Interpreting Soil Test Results written by Pam Hazelton and published by CSIRO PUBLISHING. This book was released on 2016-11-01 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Interpreting Soil Test Results is a practical reference enabling soil scientists, environmental scientists, environmental engineers, land holders and others involved in land management to better understand a range of soil test methods and interpret the results of these tests. It also contains a comprehensive description of the soil properties relevant to many environmental and natural land resource issues and investigations. This new edition has an additional chapter on soil organic carbon store estimation and an extension of the chapter on soil contamination. It also includes sampling guidelines for landscape design and a section on trace elements. The book updates and expands sections covering acid sulfate soil, procedures for sampling soils, levels of nutrients present in farm products, soil sodicity, salinity and rainfall erosivity. It includes updated interpretations for phosphorus in soils, soil pH and the cation exchange capacity of soils. Interpreting Soil Test Results is ideal reading for students of soil science and environmental science and environmental engineering; professional soil scientists, environmental scientists, engineers and consultants; and local government agencies and as a reference by solicitors and barristers for land and environment cases.

Copublished by ASCE and the Water Environment Federation. Design and Construction of Urban Stormwater Management Systems presents a comprehensive examination of the issues involved in engineering urban stormwater systems. This Manual?which updates relevant portions of Design and Construction of Sanitary and Storm Sewers, MOP 37?reflects the many changes taking place in the field, such as the use of microcomputers and the need to control the quality of runoff as well as the quantity. Chapters are prepared by authors with experience and expertise in the particular subject area. The Manual aids the practicing engineer by presenting a brief summary of currently accepted procedures relating to the following areas: financial services; regulations;Ø surveys and investigations;Ø design concepts and master planning;Ø hydrology and water quality;Ø storm drainage hydraulics; andØ computer modeling.

Download or read book Groundwater Hydrology of Springs written by Neven Kresic and published by Butterworth-Heinemann. This book was released on 2009-08-29 with total page 593 pages. Available in PDF, EPUB and Kindle. Book excerpt: Groundwater Hydrology of Water Resource Series - Water is an essential environmental resource and one that needs to be properly managed. As the world places more emphasis on sustainable water supplies, the demand for expertise in hydrology and water resources continues to increase. This series is intended for professional engineers, who seek a firm foundation in hydrology and an ability to apply this knowledge to solve problems in water resource management. Future books in the series are: Groudwater Hydrology of Springs (2009), Groudwater Hydrology of River Basins (2009), Groudwater Hydrology of Aquifers (2010), and Groudwater Hydrology of Wetlands (2010). First utilized as a primary source of drinking water in the ancient world, springs continue to supply many of the world's cities with water. In recent years their long-term sustainability is under pressure due to an increased demand from groundwater users. Edited by two world-renowned hydrologists, Groundwater Hydrology of Springs: Theory, Management, and Sustainability will provide civil and environmental engineers with a comprehensive reference for managing and sustaining the water quality of Springs. With contributions from experts from around the world, this book cover many of the world's largest springs, providing a unique global perspective on how engineers around the world are utilizing engineering principles for coping with problems such as: mismanagement, overexploitation and their impacts both water quantity and quality. The book will be divided into two parts: part one will explain the theory and principles of hydrology as they apply to Springs while part two will provide a rare look into the engineering practices used to manage some of the most important Springs from around the world. Description of the spring and the aquifer feeding it Latest groundwater and contaminant transport models Description of sources of aquifer use Understanding of contamination and/or possible contamination A plan for management and sustainability

Download or read book Where We Find Ourselves written by Margaret Sartor and published by UNC Press Books. This book was released on 2018-11-08 with total page 185 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-taught photographer Hugh Mangum was born in 1877 in Durham, North Carolina, as its burgeoning tobacco economy put the frontier-like boomtown on the map. As an itinerant portraitist working primarily in North Carolina and Virginia during the rise of Jim Crow, Mangum welcomed into his temporary studios a clientele that was both racially and economically diverse. After his death in 1922, his glass plate negatives remained stored in his darkroom, a tobacco barn, for fifty years. Slated for demolition in the 1970s, the barn was saved at the last moment--and with it, this surprising and unparalleled document of life at the turn of the twentieth century, a turbulent time in the history of the American South. Hugh Mangum's multiple-image, glass plate negatives reveal the open-door policy of his studio to show us lives marked both by notable affluence and hard work, all imbued with a strong sense of individuality, self-creation, and often joy. Seen and experienced in the present, the portraits hint at unexpected relationships and histories and also confirm how historical photographs have the power to subvert familiar narratives. Mangum's photographs are not only images; they are objects that have survived a history of their own and exist within the larger political and cultural history of the American South, demonstrating the unpredictable alchemy that often characterizes the best art--its ability over time to evolve with and absorb life and meaning beyond the intentions or expectations of the artist.
