Mechanics of Bio-Sediment Transport

The main focus of this book is the transport mechanics of sediment particles coated with microbial biofilm, which is called bio-sediment. The book also addresses the question of how to measure and simulate the considerable variation in the properties of natural sediment associated with microbial biofilm, ranging from the micro-scale surface morphology to the macro-scale sediment transport. Nowadays most studies to elucidate the mechanisms of sediment transport have concentrated on physical-chemical sediment properties, little work explicitly coupled sediment dynamics and the environmental effects under the influence of micro-ecosystem, thus leaving a serious gap in water and sediment science...

A young girl suicided because she couldn't bear the evil's bully. Then her best friend, a young boy who grew up with her together, decided to revenge as well as get justice for her. He worked really hard, which inspired the potential of the peerless genius inside of him. Then he rose suddenly at an amazing speed and he went on the way of a strong hero. His motto is that,"If you hurt me, you would get a double revenge. If you hurt someone i love, i would revenge for thousands of times." ☆About the Author☆ Xiang Yanxiajiu is an outstanding novelist and he does well in fantasy novels. He has written prenty of fantasy novels. Each of his work is boutique. The novels he has written get lots of ups and downs plots, which is exciting. Both his stories and writing are excellent.

Mechanical Engineering and Technology

The volume includes a set of selected papers extended and revised from the 2011 International Conference on Mechanical Engineering and Technology, held on London, UK, November 24-25, 2011. Mechanical engineering technology is the application of physical principles and current technological developments to the creation of useful machinery and operation design. Technologies such as solid models may be used as the basis for finite element analysis (FEA) and / or computational fluid dynamics (CFD) of the design. Through the application of computer-aided manufacturing (CAM), the models may also be used directly by software to create "instructions" for the manufacture of objects represented by the models, through computer numerically controlled (CNC) machining or other automated processes, without the need for intermediate drawings. This volume covers the subject areas of mechanical engineering and technology, and also covers interdisciplinary subject areas of computers, communications, control and automation. We hope that researchers, graduate students and other interested readers benefit scientifically from the book and also find it stimulating in the process.

  • Publisher: MDPI

Nowadays, the degree and scale of flood hazards has been massively increasing as a result of the changing climate, and large-scale floods jeopardize lives and properties, causing great economic losses, in the inundation-prone areas of the world. Early flood warning systems are promising countermeasures against flood hazards and losses. A collaborative assessment according to multiple disciplines, comprising hydrology, remote sensing, and meteorology, of the magnitude and impacts of flood hazards on inundation areas significantly contributes to model the integrity and precision of flood forecasting. Methodologically oriented countermeasures against flood hazards may involve the forecasting of...

  • Publisher: CRC Press

Wastewater Treatment: Recycling, Management, and Valorization of Industrial Solid Wastes bridges the gap between the theory and applications of wastewater treatments, principles of diffusion, and the mechanism of biological and industrial treatment processes. It presents the practical applications that illustrate the treatment of several types of data, providing an overview of the characterization and treatment of wastewaters, and then examining the different biomaterials and methods for the evaluation of the treatment of biological wastewaters. Further, it considers the various types of industrial wastewater treatment, separation, and characterization of industrial wastewater. The book serves as a valuable resource for practicing engineers and students who are interested in the field of wastewater treatment. Features: Presents the latest technologies in water treatment, including nanomaterials for industrial wastewater Covers different treatments for various industrial wastewaters, including chemical and pharmaceutical waste Includes forward-thinking analysis including conclusions and recommendations for water reuse programs

Large Dams in Asia

Large Dams in Asia

This book explores the multi-dimensional asymmetries of scale, time, and directions in the large dam controversy with a regional focus on Asia, especially on India and China. Whereas the concept of large-scale transformation of fluvial environments into technological hydroscapes originated in the West, widespread construction of large dams started in the countries of the Global South in the period after decolonisation. Construction and operation of large dams are amongst the most prestigious but also most sensitive development issues, often accompanied by massive resistance of adversely affected people and civil society organisations. Based on the notion of a contested politicised environment, various case studies are analysed to identify the dominant narratives and imaginations that shape the large dams debate. This volume largely contains contributions related to several subprojects from within the Cluster of Excellence ‘Asia and Europe in a Global Context: Shifting Asymmetries in Cultural Flows’, based at Heidelberg University, with several expert contributions from external researchers.

  • Publisher: MDPI

The state-of-the-art in water-worked bed hydraulics can only be examined through a careful exploration of the experimental (both laboratory and field) results via theoretical development. This book is primarily focused on the research aspects that involve a comprehensive knowledge of sediment dynamics in turbulent flows, as the most up-to-date research findings in the field are presented. It begins with two reviews on bedload transport and water-work bed experimental studies. The sediment dynamics is then analyzed from a classical perspective by applying the mean bed shear approach and additionally incorporating a statistical description for the role of turbulence. The work finally examines the local scour problems at hydraulic structures and results from field studies. It is intended as a course guide for field professionals, keeping up with modern technological developments. Therefore, as a simple prerequisite, readers should have a basic knowledge of hydraulics to an undergraduate level.
