Download or read book Winter Water Quality Survey of the West Fork Des Moines River written by and published by . This book was released on 1979 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: A water quality study of the West Fork Des Moines River was performed on 13, 14 February 1979. The purpose of the survey was to assess the impact of several point source waste discharges on the receiving stream during winter conditions. Compared to previous studies, data from the present survey indicates an overall improvement i n winter water quality of the West Fork Des Moines River. The most notable improvement in water quality was observed downstream from Estherville and may be attributed to a higher quality discharge from its new wastewater treatment plant. In general, most water quality parameters were in expected ranges for winter conditions. Dissolved oxygen samples collected over a twenty-four hour period varied only slightly, demonstrating the impact heavy ice and snow cover has on dissolved oxygen. Compliance sampling of several wastewater treatment plants demonstrated that the municipalities of West Bend and Rolfe were not in compliance with their discharge limitations.

Download or read book Karst Hydrogeology and Human Activities Impacts Consequences and Implications written by David Drew and published by Routledge. This book was released on 2017-10-05 with total page 311 pages. Available in PDF, EPUB and Kindle. Book excerpt: One quarter of the world's population lives in karst terrains, yet karsts are highly vulnerable to stresses caused by human activity. This book surveys human impact on karst water, showing that the increasing pollution of the environment has, to a great extent, spoiled sensitive karst ecosystems. This text examines such consequences and offers proposals for future solutions and strategies. Part One provides an overview of the functioning of karsts and of human interaction with karst environments over several millennia. Part Two consists of a systematic examination of the major areas of human activity affecting karst waters, such as agriculture, industry, mining and water exploitation. Finally, Part Three views the effects on karst groundwater within a broader societal and legislative perspective and considers possible changes of methodology and approach.

Download or read book Physics and Chemistry of Lakes written by Abraham Lerman and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: A lake, as a body of water, is in continuous interaction with the rocks and soils in its drainage basin, the atmosphere, and surface and groundwaters. Human industrial and agricultural activities introduce new inputs and processes into lake systems. This volume is a selection of ten contributions dealing with diverse aspects of lake systems, including such subjects as the geological controls of lake basins and their histories, mixing and circulation patterns in lakes, gaseous exchange between the water and atmosphere, and human input to lakes through atmospheric precipitation and surficial runoff. This work was written with a dual goal in mind: to serve as a textbook and to provide professionals with in-depth expositions and discussions of the more important aspects of lake systems.

Download or read book A Handbook of Global Freshwater Invasive Species written by Robert A. Francis and published by Routledge. This book was released on 2012-03-12 with total page 918 pages. Available in PDF, EPUB and Kindle. Book excerpt: Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives. This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms. The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.

Download or read book Methods in Stream Ecology written by F. Richard Hauer and published by Academic Press. This book was released on 2011-04-27 with total page 894 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods in Stream Ecology, Second Edition, provides a complete series of field and laboratory protocols in stream ecology that are ideal for teaching or conducting research. This updated edition reflects recent advances in the technology associated with ecological assessment of streams, including remote sensing. In addition, the relationship between stream flow and alluviation has been added, and a new chapter on riparian zones is also included. The book features exercises in each chapter; detailed instructions, illustrations, formulae, and data sheets for in-field research for students; and taxanomic keys to common stream invertebrates and algae. With a student-friendly price, this book is key for all students and researchers in stream and freshwater ecology, freshwater biology, marine ecology, and river ecology.

Download or read book Missouri Landscapes written by Jon L. Hawker and published by . This book was released on 1992 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In this magnificent book, Oliver Schuchard provides more than sixty-five exquisite black-and-white photographs spanning his thirty-eight years of photography. In addition, he explains the aesthetic rationale and techniques he used in order to produce these photographs, emphasizing the profound differences between, yet necessary interdependence of, craft and content. Although Schuchard believes that craft is important, he maintains that the idea behind the photograph and the emotional content of the image are equally vital and are, in fact, functions of one another. The author also shares components of his life experience that he believes helped shape his development as an artist and a teacher. He chose the splendid photographs included in this book from among nearly 5,000 negatives that had been exposed all over the world, from Missouri to Maine, California, Alaska, Colorado, France, Newfoundland, and Hawaii, among many other locations. Approximately 250 negatives survived the initial review, and each of those was printed before a final decision was made on which photographs were to be featured in the book. The final choices are representative of Schuchard's work and serve to substantiate his belief that craft, concept, and self must be fully understood and carefully melded for a good photograph to occur. This amazing work by award-winning photographer Oliver Schuchard will be treasured by professional and amateur photographers alike, as well as by anyone who simply enjoys superb photography."--Publishers website.
