The Ebro is a typical Mediterranean river characterized by seasonal low flows and extreme flush effects, with important agricultural and industrial activity that has caused heavy contamination problems. This volume deals with soil-sediment-groundwater related issues in the Ebro river basin and summarizes the results generated within the European Union-funded project AquaTerra. The following topics are highlighted: Hydrology and sediment transport and their alterations due to climate change, aquatic and riparian biodiversity in the Ebro watershed, occurrence and distribution of a...

Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC) have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and...

This book presents dynamic response, vibration characteristics, and nonlinear behavior of complex oil and gas well string by using a combination of theoretical methods, numerical simulation, and experimental analysis. It lays both theoretical and experimental foundation for the design of oil and gas well string parameters. The theoretical methods involved mainly include Hamilton's principle, finite element method, and energy method, while experimental methods involved include similarity principle, vibration testing method, and modal analysis method. It is a valuable reference for both...

Land deterioration, drought, desertification, and water resources shrinkage threaten natural resources, negatively impacting environmental, economic, and political stability. The increasing occurrence of climate change (extremes) impacts land degradation processes, soil erosion by water and wind, and salinization. The researchers have invested several years of scientific research in natural resources deterioration, including soil degradation and erosion, land degradation, desertification, and climate changes, which are interesting enough. However, the link between science and policymaking...
