Sediment Transport and Morphodynamics Modelling for Coasts and Shallow Environments
by Vanesa MagarThis reference for engineers, and graduate students covers sediment transport and morphodynamics modelling in nearshore environments. It presents the fundamentals required for understanding the physics and for setting up numerical models. This book covers hydrodynamics of estuarine and coastal environments, properties of seafloor and estuarine composition, and hydroenvironmental interactions; emphasising the inter-relations of small- and large-scale processes, and short- and large-evolution timescales. The focus is, principally, on the application of shallow-water theory, but some surface wave models, and coupling of shallow-water models with surface waves is also discussed to some extent. The guidance on running regional models and the case studies presented are directed to managed realignment, coastal protection, climate change impacts, and offshore renewables. Key features: Gives a balanced review of this rich interdisciplinary area Bridges practical engineering and research Offers both large- and small-scale application Suits graduate students and researchers as well as consulting engineers Vanesa Magar is a senior researcher and associate professor at the Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE) in Baja California, Mexico.

Sediment Transport in Irrigation Canals: A New Approach (IHE Delft Lecture Note Series)
by Herman Depeweg Krishna P. Paudel Néstor Méndez VSediment transport in irrigation canals influences to a great extent the sustainability of an irrigation system. Unwanted erosion or deposition will not only increase maintenance costs, but may also lead to unfair, unreliable and unequitable distribution of irrigation water to the end users. Proper knowledge of the characteristics, including behaviour and transport of sediment will help to design irrigation systems, plan effi cient and reliable water delivery schedules, to have a controlled deposition of sediments, to estimate and arrange maintenance activities, etc. The main aim of these lecture notes is to present a detailed analysis and physical and mathematical descriptions of sediment transport in irrigation canals and to describe the mathematical model SETRIC that predicts the sediment transport, deposition and entrainment rate as function of time and place for various flow conditions and sediment inputs. The model is typically suited for the simulation of sediment transport under the particular conditions of non-wide irrigation canals where the flow and sediment transport are strongly determined by the operation of the flow control structures. The lecture notes will contribute to an improved understanding of the behaviour of sediments in irrigation canals. They will also help to decide on the appropriate design of the system, the water delivery plans, to evaluate design alternatives and to achieve an adequate and reliable water supply to the farmers.

Sedimentation and Sustainable Use of Reservoirs and River Systems / Sédimentation et Utilisation Durable des Réservoirs et Systèmes Fluviaux (ICOLD Bulletins Series)
by ICOLD CIGBICOLD Bulletin 147 discusses the upstream and downstream fluvial morphological impacts of reservoir sedimentation and possible mitigation measures. The current state of and possible future sediment deposition in reservoirs have been investigated globally with the aid of the ICOLD Register on Dams. The global mean reservoir sedimentation rate was found to be 0.8 % of the original storage capacity per year. The book also investigates the impacts of dams on the ecology related to fluvial morphological changes, and guidelines are proposed to mitigate the impacts on the downstream river morphology. Finally an economical model is presented which considers a life cycle approach for reservoir conservation. Ce CIGB Bulletin 147 traite des impacts morphologiques fluviaux en amont et en aval de la sédimentation des réservoirs et des mesures d'atténuation possibles. L'état actuel et l'avenir possible du dépôt de sédiments dans les réservoirs ont été étudiés à l'échelle mondiale à l'aide du registre des barrages de la CIGB. Le taux moyen mondial de sédimentation des réservoirs s'est avéré être de 0,8 % de la capacité de stockage initiale par an. Le livre étudie également les impacts des barrages sur l'écologie liés aux changements morphologiques fluviaux, et des directives sont proposées pour atténuer les impacts sur la morphologie des rivières en aval. Enfin, un modèle économique est présenté qui prend en compte une approche de cycle de vie pour la conservation des réservoirs.

Sedition Hunters: How January 6th Broke the Justice System
by Ryan J. ReillyThe January 6th attack is an unprecedented crime in American history. Sprawling and openly political, it can't be handled by the traditional rules and norms of law enforcement--threatening the very idea of justice and its role in society. The attack on the Capitol building following the 2020 election was an extraordinarily large and brazen crime. Conspiracies were formed on social media in full public view, the law-breakers paraded on national television with undisguised faces, and with outgoing President Donald Trump openly cheering them on. The basic concept of law enforcement--investigators find criminals and serve justice--quickly breaks down in the face of such an event. The system has been strained by the sheer volume of criminals and the widespread perception that what they did wasn't wrong. A mass of online tipsters--"sedition hunters"--have mobilized, simultaneously providing the FBI with valuable intelligence and creating an ethical dilemma. Who gets to serve justice? How can law enforcement still function as a pillar of civil society? As the foundations of our government are questioned, the FBI and Department of Justice are the first responders to a crisis of democracy and law that threatens to spread, and fast. In this work of extraordinary reportage, Ryan Reilly gets to know would-be revolutionaries, obsessive online sleuths, and FBI agents, and shines a light on a justice system that's straining to maintain order in our polarized country. From the moment the police barriers were breached on January 6th, 2021, Americans knew something had profoundly changed. Sedition Hunters is the fascinating, high-stakes story of what happens next.

See Sooner, Act Faster: How Vigilant Leaders Thrive in an Era of Digital Turbulence (Management on the Cutting Edge)
by Paul J. Schoemaker George S. DayHow organizations can anticipate threats, spot opportunities, and act faster when the time is right; with rich examples including Adobe, MasterCard, and Amazon.When turbulence is the new normal, an organization's survival depends on vigilant leadership that can anticipate threats, spot opportunities, and act quickly when the time is right. In See Sooner, Act Faster, strategy experts George Day and Paul Schoemaker offer tools for thriving when digital advances intensify turbulence. Vigilant firms have greater foresight than their rivals, while vulnerable firms often miss early signals of external threats and organizational challenges. Charles Schwab, for example, was early to see and act on the promise of “robo-advisors”; Honeywell, on the other hand, stumbled when Nest Labs came out first with a “smart” thermostat. Day and Schoemaker show leaders how to assess their vigilance capabilities and cultivate insight and foresight throughout their organizations. They draw on a range of cases, including Adobe and Intuit's move to the cloud, Shell's investment in clean energy, and MasterCard's early recognition of digital challenges. Day and Schoemaker describe how to allocate the scarce resource of attention, how to detect weak signals and separate them from background noise, and how to respond strategically before competitors do. The challenge is not just to act faster but to act wisely, and the authors suggest ways to create dynamic portfolios of options. Finally, they offer an action agenda, with tips for fostering vigilance and agility throughout an organization. The rewards are stronger market positions, higher profits and growth, more motivated employees, and organization longevity.
Seed Activism: Patent Politics and Litigation in the Global South (Food, Health, and the Environment)
by Karine E. PeschardHow lawsuits around intellectual property in Brazil and India are impacting the patentability of plants and seeds, farmers&’ rights, and the public interest.Over the past decade, legal challenges have arisen in the Global South over patents on genetically modified crops. In this ethnographic study, Karine E. Peschard explores the effects of these disputes on people&’s lives, while uncovering the role of power—material, institutional, and discursive—in shaping laws and legal systems. The expansion of corporate intellectual property (IP), she shows, negatively impacts farmers&’ rights and, by extension, the right to food, since small farms produce the bulk of food for domestic consumption. Peschard sees emerging a new legal common sense concerning the patentability of plant-related inventions, as well as a balance among IP, farmers&’ rights, and the public interest.Peschard examines the strengthening of IP regimes for plant varieties, the consolidation of the global biotech industry, the erosion of agrobiodiversity, and farmers&’ dispossession. She shows how litigants question the legality of patents and private IP systems implemented by Monsanto for royalties on three genetically modified crop varieties, Roundup Ready soybean in Brazil and Bt cotton and Bt eggplant in India. Peschard argues that these private IP systems have rendered moot domestic legislation on plant variety protection and farmers&’ rights. This unprecedented level of corporate concentration in such a vital sector raises concerns over the erosion of agricultural biodiversity, farmers&’ rights and livelihoods, food security, and, ultimately, the merits of extending IP rights to higher life forms such as plants.
Seed Biology and Yield of Grain Crops
by Dennis EgliThis new edition of an established title examines the determination of grain crop yield from a unique perspective, by concentrating on the influence of the seed itself. As the food supply for an expanding world population is based on grain crops harvested for their seeds, understanding the process of seed growth and its regulation is crucial to our efforts to increase production and meet the needs of that population. Yield of grain crops is determined by their assimilatory processes such as photosynthesis and the biosynthetic processes in the seed, which are partly regulated within the seed itself. Providing a timely update in this field and highlighting the impact of the seed on grain crop yields, this book: · Describes all aspects of seed growth and development, including environmental and genetic effects on growth rate and length of the filling period. · Discusses the role of the seed in determining the two main yield components: individual seed weight and number of seeds per unit area. · Uses the concepts and models that have been developed to understand crop management and yield improvement. Substantially updated with new research and further developments of the practical applications of the concepts explored, this book is essential reading for those concerned with seed science and crop yield, including agronomists, crop physiologists, plant breeders, and extension workers. It is also a valuable source of information for lecturers and graduate students of agronomy and plant physiology.

Seed Development: OMICS Technologies toward Improvement of Seed Quality and Crop Yield
by Ganesh K. Agrawal Randeep RakwalThe book is about the seed development in the model and crop plants. Seed development is a key step of the plant life cycle that determines the nutrient value of seeds - the life for human civilization, growth, and development. The nutrient value of seeds is mainly due to storage reserve products such as carbohydrates, lipids (triacylglycerols), and proteins. The book primarily focuses on application of the 21st century high-throughput technologies transcriptomics, proteomics, metabolomics, and systems biology in near complete understanding of the various processes involved in seed development in different crop plants. The book reveals how such technologies have revolutionized our understanding of the multilayer processes and regulations involved therein by generating large-scale datasets. Accumulated datasets provide basic knowledge to develop integrated strategies to eventually improve the nutritional value of plant seed and crop yield, a critical goal in food security issues around the globe.

Seed Libraries: And Other Means of Keeping Seeds in the Hands of the People
by Cindy ConnerHistorically, seed companies were generally small, often family-run businesses. Because they were regionally based, they could focus on varieties well-suited to the local environment. <P><P>A Pacific Northwest company, for example, would specialize in different cultivars than a company based in the Southeast. However the absorption of these small, independent seed businesses into large multinationals, combined with the advancement of biotechnology resulting in hybrids and GMO seeds, has led to a serious loss of genetic diversity. The public is now at the mercy of the corporations that control the seeds.In the past few years, gardeners have realized the inherent danger in this situation. A growing movement is striving to preserve and expand our stock of heritage and heirloom varieties through seed saving and sharing opportunities. Seed Libraries is a practical guide to saving seeds through community programs, including: Step-by-step instructions for setting up a seed library A wealth of ideas to help attract patrons and keep the momentum going Profiles of existing libraries and other types of seed saving partnershipsWhoever controls the seeds controls the food supply. By empowering communities to preserve and protect the genetic diversity of their harvest, Seed Libraries is the first step towards reclaiming our self-reliance while enhancing food security and ensuring that the future of food is healthy, vibrant, tasty, and nutritious.Cindy Conner is a permaculture educator, founder of Homeplace Earth and producer of two popular instructional gardening DVDs.

Seed Money: Monsanto's Past And Our Food Future
by Bartow J. ElmoreAn authoritative and eye-opening history that examines how Monsanto came to have outsized influence over our food system. Monsanto, a St. Louis chemical firm that became the world’s largest maker of genetically engineered seeds, merged with German pharma-biotech giant Bayer in 2018—but its Roundup Ready® seeds, introduced twenty-five years ago, are still reshaping the farms that feed us. When researchers found trace amounts of the firm’s blockbuster herbicide in breakfast cereal bowls, Monsanto faced public outcry. Award-winning historian Bartow J. Elmore shows how the Roundup story is just one of the troubling threads of Monsanto’s past, many told here and woven together for the first time. A company employee sitting on potentially explosive information who weighs risking everything to tell his story. A town whose residents are urged to avoid their basements because Monsanto’s radioactive waste laces their homes’ foundations. Factory workers who peel off layers of their skin before accepting cash bonuses to continue dirty jobs. An executive wrestling with the ethics of selling a profitable product he knew was toxic. Incorporating global fieldwork, interviews with company employees, and untapped corporate and government records, Elmore traces Monsanto’s astounding evolution from a scrappy chemical startup to a global agribusiness powerhouse. Monsanto used seed money derived from toxic products—including PCBs and Agent Orange—to build an agricultural empire, promising endless bounty through its genetically engineered technology. Skyrocketing sales of Monsanto’s new Roundup Ready system stunned even those in the seed trade, who marveled at the influx of cash and lavish incentives into their sleepy sector. But as new data emerges about the Roundup system, and as Bayer faces a tide of lawsuits over Monsanto products past and present, Elmore’s urgent history shows how our food future is still very much tethered to the company’s chemical past.
