Integrating information from several areas of engineering geology, hydrogeology, geotechnical engineering, this book addresses the general field of groundwater from an engineering perspective. It covers geological engineering as well as hydrogeological and environmental geological problems caused by groundwater engineering. It includes 10 chapters, i.e., basic groundwater theory, parameter calculation in hydrogeology, prevention of geological problem caused by groundwater, construction dewatering, wellpoint dewatering methods, dewatering wells and drilling, groundwater dewatering in foundation-pit engineering, groundwater engineering in bedrock areas, numerical simulation in groundwater engineering, groundwater corrosion on concrete and steel. Based on up-to-date literature, it describes recent developments and presents several case studies with examples and problems. It is an essential reference source for industrial and academic researchers working in the groundwater field and can also serve as lecture-based course material providing fundamental information and practical tools for both senior undergraduate and postgraduate students in fields of geology engineering, hydrogeology, geotechnical engineering or to conduct related research.

Invariant Imbedding T-matrix Method for Light Scattering by Nonspherical and Inhomogeneous Particles propels atmospheric research forward as a resource and a tool for understanding the T-Matrix method in relation to light scattering. The text explores concepts ranging from electromagnetic waves and scattering dyads to the fundamentals of the T-Matrix method. Providing recently developed material, this text is sufficient to aid the light scattering science community with current and leading information. Enriched with detailed research from top field experts, Invariant Imbedding T-matrix Method for Light Scattering by Nonspherical and Inhomogeneous Particles offers a meaningful and essential presentation of methods and applications, with a focus on the light scattering of small and intermediate particles that supports and builds upon the latest studies. Thus, it is a valuable resource for atmospheric researchers and other earth and environmental scientists to expand their knowledge and understanding of available tools.

This research volume outlines the scientific foundations that are central to our current understanding of light scattering, absorption and polarization processes involving ice crystals. It also demonstrates how data from satellite remote sensing of cirrus clouds can be combined with radiation parameterizations in climate models to estimate the role of these clouds in temperature and precipitation responses to climate change. Providing a balanced treatment of the fundamentals and applications, this book synthesizes the authors' own work, as well as that of other leading researchers in this area. Numerous illustrations are included, including three-dimensional schematics, to provide a concise discussion of the subject and enable easy visualization of the key concepts. This book is intended for active researchers and advanced graduate students in atmospheric science, climatology, and remote sensing, as well as scholars in related fields such as ice microphysics, electromagnetic wave propagation, geometric optics, radiative transfer and cloud-climate interactions.

Two concepts, stationary cooling and trailing cooling, were proposed to prevent weld intersection cracking. Finite element analysis was used to demonstrate the potential effectiveness of those two concepts. Both stationary and trailing heat sink setups were proposed for preventing intersection cracking. The cooling media could be liquid nitrogen, or pressured air knife. Welding experiments on the small test panel with the localized heat sink confirmed the feasibility of using such a stationary cooling technique. The required cooling was achieved in this test panel. Systematic welding experiments should be conducted in the future to validate and refine the heat sink technique for preventing intersection cracking.
