Description
The book describes an integrated theory that links estuary shape to tidal hydraulics, tidal mixing and salt intrusion. The shape of an
alluvial estuary is characterised by exponentially varying width and the absence of bottom slope. This topography is closely related
to tidal parameters, hydraulic parameters and parameters that describe 1-dimensional mixing and salt intrusion. Starting from the fundamental
equations for conservation of mass and momentum, analytical equations are derived that relate the topography to tidal parameters (tidal
excursion, phase lag, tidal damping, tidal amplification), wave celerity, lateral and vertical mixing and salt intrusion.
The book
presents a review of the state of the art, a comprehensive theoretical background and ample case illustrations from all over the world.
It provides tools with which human interference in estuary dynamics can be described and predicted, resulting from, for instance: upstream
fresh water abstraction, dredging, climate change or sea-level rise. In describing the interactions between tide, topography, water quality
and river discharge, it provides useful information for hydraulic engineers, morphologists, ecologists and people concerned with water
quality in alluvial estuaries.
Although the book can be used as a text book, it is mainly a monograph aimed at graduate students and
researchers.
Audience
Ecologists, morphologists, hydraulic engineers
