Coastal Wetlands, Second Edition: An Integrated and Ecosystem Approach provides an understanding of the functioning of coastal ecosystems and the ecological services that they provide. As coastal wetlands are under a great deal of pressure from the dual forces of rising sea levels and the intervention of human populations, both along the estuary and in the river catchment, this book covers important issues, such as the destruction or degradation of wetlands from land reclamation and infrastructures, impacts from the discharge of pollutants, changes in river flows and sediment supplies, land clearing, and dam operations. - Covers climate change and its influence on coastal wetland form and function - Provides a fully updated and expanded resource, including new chapters on modeling, management and the impact of climate change - Contains full-color figures of wetlands and estuaries in different parts of the world

Climate and anthropogenic changes impact the conditions of erosion and sediment transport in rivers. Rainfall variability and, in many places, the increase of rainfall intensity have a direct impact on rainfall erosivity. Increasing changes in demography have led to the acceleration of land cover changes in natural areas, as well as in cultivated areas, and, sometimes, in degraded areas and desertified landscapes. These anthropogenized landscapes are more sensitive to erosion. On the other hand, the increase in the number of dams in watersheds traps a great portion of sediment fluxes, which do not reach the sea in the same amount, nor at the same quality, with consequences on coastal geomorphodynamics. This book is dedicated to studies on sediment fluxes from continental areas to coastal areas, as well as observation, modeling, and impact analysis at different scales from watershed slopes to the outputs of large river basins. This book is concentrated on a number of keywords: “erosion” and “sediment transport”, “model” and “practice”, and “change”. The keywords are briefly discussed with respect to the relevant literature. The contributions in this book address observations and models based on laboratory and field data, allowing researchers to make use of such resources in practice under changing conditions.

This book presents key principles of the hydraulics of river basins, with a unique focus on the interplay between stream flows and sediment transport. Addressing a number of basic topics related to the hydraulics of natural waterways, it above all emphasizes applicative aspects in order to provide the reader with a solid grasp of river engineering. The first chapter explores many of the fixed base hydraulic topics that are normally neglected in traditional texts, namely the effects on motion produced by the vegetation and macroroughnesses that characterize many mountain streams. The remaining chapters are devoted entirely to hydraulics with mobile riverbeds and put particular emphasis on inhomogeneous river channels. The book’s approach goes beyond classical treatments, so as to not only introduce readers to the fundamentals of mobile riverbeds, but also enable today’s river engineers to successfully design and maintain natural riverbeds.
