Takes readers on a walk at a sheltered bay, showing examples of how the animals and plants of estuaries are connected and dependent on each other and the estuary's mix of fresh and salt water.

This classroom resource provides clear, concise scientific information in an understandable and enjoyable way about water and aquatic life. Spanning the hydrologic cycle from rain to watersheds, aquifers to springs, rivers to estuaries, ample illustrations promote understanding of important concepts and clarify major ideas. Aquatic science is covered comprehensively, with relevant principles of chemistry, physics, geology, geography, ecology, and biology included throughout the text. Emphasizing water sustainability and conservation, the book tells us what we can do personally to conserve for the future and presents job and volunteer opportunities in the hope that some students will pursue careers in aquatic science. Texas Aquatic Science, originally developed as part of a multi-faceted education project for middle and high school students, can also be used at the college level for non-science majors, in the home-school environment, and by anyone who educates kids about nature and water.

Estuaries are complex and fascinating natural environments, where constantly changing water depths generate rapidly reversing currents and transport vast quantities of salt, heat, and sediment on a daily basis. Estuaries: Monitoring and Modeling the Physical System examines these processes, offering extensive information about the geological evolution of estuaries, and details of bathymetry, tides, currents, salt and heat, and suspended sediment. By carefully building a working computer model which accurately emulates the complexities inherent in estuaries, students learn quickly to model the tides and currents, and then to build and test salinity, temperature, and suspended sediment modules. The book is supported by a supplimentary material at www.blackwellpublishing.com/hardisty which includes: * Excel routines for individual formulae and diagrams * Full coding for the estuarine model THE ANALYSIS OF TIDAL STREAM POWER – For Jack Hardisty’s other book and the accompanying website please click here: http://eu.wiley.com/WileyCDA/WileyTitle/productCd-047072451X.html

Estuaries are of high socioeconomic importance with twenty-two of the thirty-two largest cities in the world located on river estuaries. Estuaries bring together fluxes of fresh and saline water, as well as fluvial and marine sediments, and contain high biological diversity. Increasingly sophisticated field observation technology and numerical modeling have produced significant advances in our understanding of the physical properties of estuaries over the last decade. This book introduces a classification for estuaries before presenting the basic physics and hydrodynamics of estuarine circulation and the various factors that modify it in time and space. It then covers special topics at the forefront of research such as turbulence, fronts in estuaries and continental shelves, low inflow estuaries, and implications of estuarine transport for water quality. Written by leading authorities on estuarine and lagoon hydrodynamics, this volume provides a concise foundation for academic researchers, advanced students and coastal resource managers.

This timely volume examines the work of the National Estuary Program, the prominent federally-funded initiative dealing with pollution and other anthropogenic impacts on estuarine ecosystems and the management plans necessary to ensure that these invaluable natural treasures remain healthy and productive for future generations.
