Theoretical Morphodynamics: Straight Channels
This monograph presents the mechanistic foundations of the theory of Morhodynamics, a discipline that investigates the shape of the erodible boundary of natural water bodies. We focus on the fluvial Morphodynamics of straight erodible channels, providing the basis for subsequent extensions to meandering rivers (treated in the companion monograph 2 of this series) and braided rivers. We present basic notions on the Mechanics of Turbulent Flows and Sediment Transport in straight open channels with mobile beds. We then investigate their morphodynamic equilibrium and its instability, that leads to the formation of a variety of bedforms observed in natural rivers. In particular, fluvial bars will deserve special attention as the fundamental building block of large scale fluvial patterns.
Theoretical Morphodynamics: River Meandering
This monograph discusses the mechanics of Meandering Rivers with the help of the mathematical and modeling tools built up in the previous monograph of the same Authors (monograph 1 of the present series). After introducing the reader to the ubiquitous character of meandering streams, we discuss the hydrodynamics of curved channels with fixed beds and banks. Next, we extend the analysis to account for the mobile character of the bed and show that it gives rise to the alternate sequence of riffles and pools that characterize river meanders. Allowing for the erodible character of the river banks then allows to build up a rational theory of meander formation able to explain most of the features observed in nature: meander growth, migration, skewing, multiple loops, cutoffs and meander belts.
Flooding and Environmental Challenges for Venice and Its Lagoon
A technical volume exploring the prospects for decreasing the level of flooding in and around Venice.
Goodbye New York
James guida rilassato, lungo il tragitto che porta verso Villa Margherita, residenza di Elisabetta, nel piccolo paesino della campagna friulana. Lui vorrebbe che quel viaggio non avesse fine, sarebbe come stare in un mondo creato solo per loro due e vivere nel respiro l’uno dell’altra. James ferma il suo maggiolino rosso, nel punto dove, esattamente due mesi prima, si era scontrato con la Volvo di Elisabetta. Ora lì c’è un piedistallo di pietra con sopra un cestello pieno di foglie di vite secche, dove spicca un biglietto. Scendono, James lo prende, glielo porge: «Qui sono arrivato da New York con la speranza di trovare il senso vero della mia vita. Qui ho incontrato il tuo sorriso e la mia vita si è illuminata. Desidero vivere con te Ely ogni giorno a venire, se anche tu lo vuoi. Solo per questo dirò: Goodbye New York!».

Mechanics of Coastal Sediment Transport
This book treats the subject of sediment transport in the marine environment, covering transport of non-cohesive sediment by waves and current in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required. It is intended for M.Sc. and Ph.D. students. The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. It does not present a large number of different formulae for the sediment transport rates under various conditions. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described; in the second, sediment ...
Coastal Bottom Boundary Layers And Sediment Transport
This book is intended as a useful handbook for professionals and researchers in the areas of Physical Oceanography, Marine Geology, Coastal Geomorphology and Coastal Engineering and as a text for graduate students in these fields. With its emphasis on boundary layer flow and basic sediment transport modelling, it is meant to help fill the gap between general hydrodynamic texts and descriptive texts on marine and coastal sedimentary processes. The book commences with a review of coastal bottom boundary layer flows including the boundary layer interaction between waves and steady currents. The concept of eddy viscosity for these flows is discussed in depth because of its relation to sediment d...
