This book was released on 2017 with total page 76 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the nature of stream-aquifer interaction is important for understanding the degree of hydraulic connection between streams and adjacent aquifers within any given watershed. Such information is necessary before the effects of groundwater pumping on streamflow, or the effects of surface-water runoff on aquifer recharge, can be assessed. Traditional techniques to analyze stream-aquifer interaction are based on digital groundwater flow models; however, aquifer parameters for model calibrations are generally unavailable or difficult and costly to obtain. Recession curve analysis is an alternative approach to determining stream-aquifer interaction Basic assumptions in recession curve analysis include: (1) no regulation on the stream, (2) stream fully penetrates the aquifer, (3) the watershed is underlined by impermeable rocks, (3) aquifer systems have uniform hydraulic conductivity and transmissivity, (4) aquifer that sustains stream flow is a one-dimensional flow regime (neglects vertical interaction with deeper aquifers), and (5) watershed has uniform storage and recharge. This study sought to investigate changes in precipitation, streamflow, baseflow, and hydrologic properties of the Pedernales watershed in central Texas, as well as identify the primary aquifer contributing flow to the Pedernales River between 1940 and 2014. The USGS Ground Water Tool Box RECESS program was used to extract meaningful segments of streamflow recession and the slope (K) of such segments (recession curve index, RCI). Man-Kendall Monotonic trend (MK) tests were used to assess changes in climatologic and hydrologic conditions during the study period. The results of annual trend analysis of precipitation, streamflow, baseflow and RCI showed no significant changes over the study period. Values of the stream-aquifer property T/a2S (where T is the transmissivity of the aquifer, a is the average distance between the stream and watershed divide, and S is the storativity of the aquifer was estimated as 0.0403/d and the watershed K value was 23.15 days/log cycle. It is concluded that the Hensel Sand (rock formation) of Cretaceous age is the primary source of baseflow to the Pedernales River above the Johnson City gage. Results of this study are relevant to water resource management in the study area to satisfy the needs o fa growing population while maintaining the ecological integrity of the stream-aquifer system. The approach used in this study is transferable to other watersheds as method requires only streamflow hydrograph and recession analysis.

Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

Download or read book Sustainable Horticultural Systems written by Dilip Nandwani and published by Springer. This book was released on 2014-10-14 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable horticulture is gaining increasing attention in the field of agriculture as demand for the food production rises to the world community. Sustainable horticultural systems are based on ecological principles to farm, optimizes pest and disease management approaches through environmentally friendly and renewable strategies in production agriculture. It is a discipline that addresses current issues such as food security, water pollution, soil health, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, entomology, ecology, chemistry and food sciences. Sustainable horticulture interprets methods and processes in the farming system to the global level. For that, horticulturists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable horticulture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable horticulture treats problem sources.

Available in PDF, EPUB and Kindle. Book excerpt: "The Freshwater Mussels of Tennessee . . . is indispensable to anyone, anywhere, working on this group. Parmalee and Bogan have written a work that sets the standard for future regional guides."--G. Thomas Watters, Ohio Biological Survey "The Freshwater Mussels of Tennessee documents a tremendously diverse and unique mussel fauna that is rapidly being destroyed by modern development. Parmalee and Bogan set a new standard for state mussel surveys in their authoritative, thorough, and and highly readable account. The book will be of interest to biologists and conservationists worldwide and will appeal to anyone who cares about the preservation of natural resources in the southeastern United States."--Robert E. Warren, Illinois State Museum With more than 150 species and subspecies recorded in the state, Tennessee has one of the most diverse freshwater mussel faunas in North America. Valuable as indicators of water quality, these mollusks have themselves become threatened as development encroaches on habitat--twenty-three are currently listed as endangered species and at least twelve have become extinct. This is the first book for Tennessee to deal with this biologically and commercially significant group of mollusks. Its authors have been studying and writing about the mussels of Tennessee for more than twenty years and have undertaken a systematic organization of a large and complex body of information to bring order to a difficult field. The book traces the long history of human exploitation of mussels, from aboriginal food gathering to the growth of the cultured pearl industry. It provides an interpretive context for its exhaustive species accounts with background material on biology, distribution, economic utilization, taxonomy, and conservation issues. The authors also review the life cycle of the mussel and describe its many remarkable traits, such as its shell formation and the strategies it employs during the larval stage in parasitizing fish. The species accounts comprise 128 members of Family Unionidae--from pigtoes and pocketbooks to lilliputs and spikes--plus four additional species. The authors cover classification and synonymy, range and distribution, life history and ecology, and survival status. Particular attention is paid to shell description and structure to assist the reader in identification. Each species account includes a distribution map and color photos of two specimens. The Freshwater Mussels of Tennessee is a major reference that encompasses historical and modern mussel collections and draws on conservation studies that span two centuries. It will stand as an authoritative guide to understanding Tennessee mollusks and as a benchmark in the study of these species worldwide. The Authors: Paul W. Parmalee is professor emeritus of zooarchaeology and director emeritus of the McClung Museum at the University of Tennessee, Knoxville. Arthur E. Bogan is curator of aquatic invertebrates at the North Carolina State Museum of Natural Sciences, Raleigh.
