Summary: Environmental hydraulis of open chanel flows
Review: This book was developed to introduce students, professionals and managers to the challenges of open channel flows and environmental hydraulics. After a concise introduction (Part 1), the second section (Part 2) deals with mixing and dispersion of matter in natural river systems. Part 3 presents an introduction to unsteady open channel flows, and the interactions between flowing water and its surroundings are discussed in Part 4.
Mixing and dispersion of contaminants in natural systems is developed in Part 2. Applications include release of organic and nutrient-rich wastewater into the ecosystem (eg. from treated
sewage effluent), smothering of seagrass and coral, stormwater runoff during flood events, and injection of heated water from an industrial discharge (e.g. at a cooling power plant). For example, during an accidental release of waste occurs in a streams, the water resource scientist needs to predict the arrival time of the contaminant cloud, the peak concentration of solute and the duration of the pollution. Basic theory of molecular diffusion and advection is extended to turbulent advective diffusion in channels. Gradually-varied flow calculations are developed in Part 3. First the basic equations of one-dimensional unsteady open channel flows are presented. That is, the Saint-Venant equations and the method of characteristics. Later simple applications are developed. The
propagation of waves, positive and negative surges are presented, while the dam break wave problem is discussed in the subsequent chapter. Simple numerical models are presented and explained later. There are strong interactions between turbulent water flows and the surrounding environment. Part 4 introduces the basic concepts of the transport of solids, and of the mixing of air and water at free-surfaces.
At the beginning of the book, the reader will find the table of contents, a list of symbols and a glossary of technical terms and names. After the conclusion, a detailed list of references is
presented. The last section presents a correction form. Readers who find an error or mistake are welcome to record the error on the page and to send a copy to the author. [...].
