第3回国際津波シンポジウム2010 好評書。
Since the publication of "Mixing in Inland and Coastal Waters" by Fischer et al.(1979) and "Estuaries, a Physical Introduction" by Dyer (1973, revised in 1997), no comprehensive theory has been published on salinity and tides in estuaries. This book combines the classical knowledge on salinity and tides with new insights that have been gained during the last decades, within one consistent theoretical framework.
Full Description
Since the publication of "Mixing in Inland and Coastal Waters" by Fischer et al.(1979) and "Estuaries, a Physical Introduction" by Dyer (1973, revised in 1997), no comprehensive theory has been published on salinity and tides in estuaries. This book combines the classical knowledge on salinity and tides with new insights that have been gained during the last decades, within one consistent theoretical framework. It provides new integrated theory for tidal hydraulics, tidal mixing and salt intrusion in alluvial estuaries. It presents a consistent set of analytical equations to compute tidal movement, tidal mixing and salt intrusion, derived from the fundamental laws of conservation of mass and momentum. It serves as a practical guide and methodology with many illustrations of applications in real estuaries.
