The aim of this publication is the understanding of large floods
and their impact on the Earth’s surface. The major objectives are:
1) to take a second look at what constitutes a megaflood that the
principle of uniformitarianism is at some loss to explain and 2) to
try to determine what could happen in such large floods by
analyzing those that occur in front of glaciers, in alluvial-fans
and in alluvial valleys.
The products of these floods are presented in terms of
sedimentary deposits, erosional features and damage to human
activities.
The volume bears out the concept that sedimentological analysis
can be a powerful tool, not only for reconstructing processes that
have acted on ancient landscapes, but also as a technique for risk
assessment of certain troubled areas. Therefore, this volume is of
interest not only to sedimentologists/gemorphlogists, but also to
engineers, landuse planners and anyone interested in the
interrelation between humans and the environment.

Preface.
1. MEGAFLOODS.
High-energy megafloods: planetary settings and sedimentary
dynamics (Victor. R. Baker).
Late-Quaternary catastrophic flooding in the Altai Mountains of
south-central Siberia: a synoptic overview and an introduction to
flood deposit sedimentology (Paul A. Carling, Alistair D. Kirkbride
, Sergei Parnachov, Pavel S. Borodavko and Glenn W. Berger).
Great Holocene floods along Jökulsá á
Fjöllum, north Iceland (Richard B. Waitt).
2. GLACIAL OUTWASH FLOODS.
November 1996 jökulhlaup on Skeidarársandur outwash
plain, Iceland (Árni Snorrason, Páll Jónsson, Or
Sigurdsson, Svanur Pálsson, Sigvaldi Árnason,
Skúli Víkingsson and Ingibjörg Kaldal).
The effects of glacier-outburst flood flow dynamics on
ice-contact deposits: November 1996 jökulhlaup,
Skeidarársandur, Iceland (Andrew J. Russell and
Óskar Knudsen).
Formation of ice-block obstacle marks during the November 1996
glacier-outburst flood (jökulhlaup),
Skeidarársandur, southern Iceland (Helen Fay).
A large-scale flood event in 1994 from the mid-Canterbury
Plains, New Zealand, and implications for ancient fluvial deposits
(Greg H. Browne).
3. ALLUVIAL-FAN FLOODS.
Alluvial-fan sedimentation from a glacial outburst flood, Lone
Pine, California, and contrasts with meteorological flood deposits
(Terence C. Blair).
Alluvial fans in the Italian Alps: sedimentary facies and
processes (Andrea Moscariello, L. Marchi , F. Maraga and G.
Mortara).
Analysis of terrestrial hyperconcentrated flows and their
deposits (Marco Benvenuti and I. Peter Martini).
Catastrophic debris-flow deposits from an inferred landslide-dam
failure, Eocene Berga Formation, eastern Pyrenees, Spain (Eloi
Saula, Emili Mató, E. and Cai Puigdefabregas).
4. ALLUVIAL VALLEY FLOODS.
Coarse-grained flood bars formed at the confluence of two
subarctic rivers affected by hydroelectric dams, Ontario, Canada
(Sara-Jane Mosher and I. Peter Martini).
Comparison of the flood response of a braided and a meandering
river, conditioned by anthropogenic and climatic changes
(Guillermina Garzón and A. Alonso).
Effects of land-use and precipitation changes on floodplain
sedimentation in the 19th And 20th century (Geul River, the
Netherlands) (Marleen. H. Stam).
Use of remote sensing in monitoring river floods and their
effects on the landscape (Lena Halounová).
5. SPECIAL CASES.
Sedimentary traces as indicator of temporary ice marginal
channels in the Westphalian Bight, Germany (Juergen Herget).
Outlet glaciers of the Pleistocene (LGM) south Tibetan ice sheet
between Cho Oyu and Shisha Pangma as potential sources of former
megafloods (Matthias Kuhle).
