This book was released on 2012-12-20 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first two decades of the U.S. Geological Survey's National Water Quality Assessment (NAWQA) Program have provided a successful and useful assessment of U.S. water-quality conditions, how they have changed over time, and how natural features and human activities have affected those conditions. Now, planning is underway for the third decade (Cycle 3) of the Program outlined in the Science Plan, with challenges including ensuring that the NAWQA remain a national program in the face of declining resources, balancing new activities against long-term studies, and maintaining focus amidst numerous and competing stakeholder demands. The Science Plan for Cycle 3 articulates a forward-thinking vision for NAWQA science over the next decade, building on the previous cycles' data, experience, and products. Preparing for the Third Decade (Cycle 3) of the National Water-Quality Assessment (NAWQA) Program explains the national needs outlined in the plan, NAWQA's need to emphasize collaboration with other USGS and external programs, other federal agencies, state and local governments, and the private sector.

Book Synopsis Herbicides and Environment by : Andreas Kortekamp
Download or read book Herbicides and Environment written by Andreas Kortekamp and published by BoD – Books on Demand. This book was released on 2011-01-08 with total page 764 pages. Available in PDF, EPUB and Kindle. Book excerpt: Herbicides are much more than just weed killers. They may exhibit beneficial or adverse effects on other organisms. Given their toxicological, environmental but also agricultural relevance, herbicides are an interesting field of activity not only for scientists working in the field of agriculture. It seems that the investigation of herbicide-induced effects on weeds, crop plants, ecosystems, microorganisms, and higher organism requires a multidisciplinary approach. Some important aspects regarding the multisided impacts of herbicides on the living world are highlighted in this book. I am sure that the readers will find a lot of helpful information, even if they are only slightly interested in the topic.

Download or read book Techniques in Aquatic Toxicology, Volume 2 written by Gary K. Ostrander and published by CRC Press. This book was released on 2005-01-27 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Following up on his popular Techniques in Aquatic Toxicology with a second volume, now nine years later, Dr. Ostrander has once again called on the top aquatic toxicologists from across the world to present 39 chapters of unique collection and testing procedures. Updating five techniques from the first volume, the authors have gone on to add over two dozen new techniques. Every chapter covers a specific procedure that can easily be reproduced by any competent technician with basic knowledge. Each of the chapter authors provides and interprets typical and anomalous results, false positives, and artifacts. Data is provided either from recently published experiments or from work being published for the first time.
Book Synopsis Lake Restoration Handbook by : David P. Hamilton
Download or read book Lake Restoration Handbook written by David P. Hamilton and published by Springer. This book was released on 2019-01-29 with total page 599 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lakes across the globe require help. The Lake Restoration Handbook: A New Zealand Perspective addresses this need through a series of chapters that draw on recent advances in modelling and monitoring tools, citizen science and First Peoples’ roles, catchment and lake-focused restoration techniques, and policy implementation. New Zealand lakes, like lakes across the globe, are subject to multiple pressures that have increased in severity and scale as land use has intensified, invasive species have spread and global climate change becomes manifest. This books builds on the popular Lake Managers Handbook (1987), which provided guidance on undertaking investigations into, and understanding lake ecosystems in New Zealand. The Lake Restoration Handbook: A New Zealand Perspective synthesises contemporary issues related to lake restoration and rehabilitation, integrated with social science and cultural viewpoints, and complemented by authoritative topic-area summaries by renowned scientists and practitioners from across the globe. The book examines the progress of lake restoration and the new and emerging tools available to managers for predicting and effecting change. The book will be a valuable resource for natural and social scientists, policy writers, lake managers, and anyone interested in the health of lake ecosystems.

Book Synopsis Assessing Pesticide Loading and Concentration with Assistance of Integrated Hydrological Models in Streams of Small to Medium-sized Watersheds by : Wei Chen

This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pesticides are increasingly used around the world alone with the expansion of intensive crop cultivation and food production. Pesticide residues from agriculture fields being carried to surface and ground water impose a potential threat to the aquatic ecosystem as well as to human health. However, monitoring potential threat of pesticide residuals in river systems is expensive and difficult. Previous studies indicated that traditionally used grab sampling methods could potentially underestimate the maximum concentrations of pesticide residues in streams by 10 to 1000 times. The objective of this study was to assess pesticide loading and concentration with assistance of integrated hydrological models in streams of small to medium-sized watersheds. Soil and Water Assessment Tool (SWAT) was selected for simulating hydrological processes together with pesticide loading and in stream pesticide concentration. Model predicted pesticide loading and pesticide concentration was compared with three years measured data from Black Brook Watershed and two Sub-basins within the same watershed. We found that the model predicted pesticide loading and in stream concentrations of three pesticides had the same seasonal trend with field surveys with some discrepancies. The discrepancies are likely caused by three main factors. 1. Model predicts the daily pesticide loading and daily average pesticide concentration and while actual pesticide concentrations change rapidly during stormflow period. 2. Current field sampling method could not capture the rapid change of pesticide concentration due to mechanical limitations. 3. Input data on exact pesticide application data were not available. In general, the pesticide modelling results indicate that the model is an effective tool in loading and concentration prediction in small agricultural watershed. We also found the model predicted pesticide loading during baseflow period were relatively high compare[d] with near zero pesticide concentration observed. This suggest[s] there is a need to improve in pesticide routing algorithm in SWAT model and current estimation during based flow period should be manually adjusted.
