Using observations of the 2011-Tohoku and some other tsunamis in rivers as a starting point for analytical and numerical exploration, this book suggests a basis for predicting tsunami impacts in a river after the wave has transitioned into the river’s channel.
This volume presents a collection of contributions that were published in "Pure and Applied Geophysics - pageoph" and which deals with the major earthquake that hit Illapel, Chile on September 16, 2015 with magnitude 8.3, and associated trans-oceanic tsunami. The subducting Nazca plate beneath the Andes caused this major earthquake, generating strong shaking, permanent deformation, free oscillations of the Earth, and tsunamis. This event occurred in the flat-angle subducting segment of the plate.The generated tsunami spread throughout the entire Pacific Ocean and was recorded by numerous coastal tide gauges and open-ocean DART stations. All articles give an up-to-date account of research in one of the most active seismic zones worldwide. An introductory article by Kenji Satake rounds this collection off.
A tidal bore is a series of waves propagating upstream as the tidal flow turns to rising. It forms during spring tide conditions when the tidal range exceeds 4 to 6 m and the flood tide is confined to a narrow funnelled estuary. Its existence is based upon a fragile hydrodynamic balance between the tidal amplitude, the freshwater river flow conditions and the river channel bathymetry, and it is shown that this balance may be easily disturbed by changes in boundary conditions and freshwater inflow. This book demystifies the physics of a tidal bore and it thoroughly documents the tidal bores on our planet with reliable and accurate information. It aims to cultivate a passion for a beautiful, but fragile geophysical process, with in-depth updated content and by over 190 illustrations and photographs.
This monograph is a compilation of a number of research studies presented in fourteen chapters dealing with the impact and restoration of coastal environments that have been affected by earthquakes and tsunamis. The focus is mainly on rivers, estuaries, coastal lagoons, beaches, and related ecosystems. In addition to direct impact and response due to flooding and subsequent abrasion, this publication covers physical, chemical and biological responses in coastal morphology, water quality and ecosystems and includes also topics dealing with risk reduction and vulnerability. This compilation mainly covers examples from large magnitude earthquake and tsunami events in the Indian and Pacific Ocean that are complemented with other events in Latin America and the Iberian Peninsula. Comprehensive descriptions of multi-scale impacts of tsunami and earthquake events, both spatially and temporally, will help the reader to understand the complicated interactions which occur in coastal zones in order to create a sustainable, resilient environment and achieve a society with smart post-event recovery planning. This book is aimed at researchers and students in coastal science and engineering as well as at policy makers, environmental planners and coastal managers.
