Submerged vanes are an unobtrusive and cost-effective way for water engineers to address many problems associated with sedimentation and river training. A relatively new technology, submerged vanes are a low-impact method for reducing erosion and downstream sediment buildup. Unlike weirs and dikes, submerged vanes bolster current efforts to re-meander—or make more natural—rivers that have been modified by humans. This book is a complete guide to help engineers determine when submerged vanes would be an effective design solution and how they should be planned and installed. Using straightforward language, this book describes the solutions that submerged vanes offer to problems plaguing modern river systems. These solutions include preventing bank erosion, increasing the flood-bearing capacity of a river by reducing sediment deposits, and keeping water intakes and diversions clear and functioning. Design calculations are illustrated for different river situations and lab results are published to explain the theory behind submerged vanes. In addition, the installation of submerged vanes is detailed in several case studies. This practical manual encourages the transfer of this eco-friendly technology from research into common practice. River Training and Sediment Management with Submerged Vanes is an essential resource for engineers involved in river engineering and channel design, as well as utility engineers, environmental officials, and managers of river and stream systems.

Biofuels have recently attracted a lot of attention, mainly as alternative fuels for applications in energy generation and transportation. The utilization of biofuels in such controlled combustion processes has the great advantage of not depleting the limited resources of fossil fuels while leading to emissions of greenhouse gases and smoke particles similar to those of fossil fuels. On the other hand, a vast amount of biofuels are subjected to combustion in small-scale processes, such as for heating and cooking in residential dwellings, as well as in agricultural operations, such as crop residue removal and land clearing. In addition, large amounts of biomass are consumed annually during forest and savanna fires in many parts of the world. These types of burning processes are typically uncontrolled and unregulated. Consequently, the emissions from these processes may be larger compared to industrial-type operations. Aside from direct effects on human health, especially due to a sizeable fraction of the smoke emissions remaining inside residential homes, the smoke particles and gases released from uncontrolled biofuel combustion impose significant effects on the regional and global climate. Estimates have shown the majority of carbonaceous airborne particulate matter to be derived from the combustion of biofuels and biomass. “Production of Biofuels and Numerical Modelling of Chemical Combustion Systems” comprehensively overviews and includes in-depth technical research papers addressing recent progress in biofuel production and combustion processes. To be specific, this book contains sixteen high-quality studies (fifteen research papers and one review paper) addressing techniques and methods for bioenergy and biofuel production as well as challenges in the broad area of process modelling and control in combustion processes.
