This book introduces the new discipline of urban oceanography, providing a deeper understanding of the physics of the coastal ocean in an urban setting. The authors explore how the coastal ocean impacts with the humans who live, work and play along its shores; and in turn how human activities impact the health and dynamics of the coastal ocean. Fundamental topics covered include: the governing dynamical equations; tidal and circulation processes; variation of salinity and freshwater fluxes; watershed pollutants; observing systems; and climate change. Bridging the gaps between the fields of engineering, physical and social sciences, economics, and policy, this book is for anyone who wishes to learn about the physics, chemistry, and biology of coastal waters. It will support an introductory course on urban oceanography at the advanced undergraduate and graduate level, and will also prove invaluable as a reference text for researchers, professionals, coastal urban planners, and environmental engineers.
