Invitation

River Flow 2004 is the second International Conference on fluvial hydraulicsand has established the periodicity of the series. Organized as specialtyconferences under the auspices of the International Association of HydraulicEngineering and Research (IAHR) with its Fluvial Hydraulics and EcoHydraulics Sections, River Flow conferences seem to be an importantmoment of aggregation for many researchers involved in river modelling andobservation. The intense land use of the last century and the lack of ade-quate sustainable development policies are probably the most importantreasons of river hazards. For the importance of water as a resource in thehuman well-being we need a better comprehension of river processes andan adequate management of fluvial areas. Scientists are aware of thisnecessity and largely contribute with their researches toward this aim. Thisclearly appears in the number of papers presented at River Flow 2004 (174)and from the number of country represented (43). Papers in this volume arerelated to the following topics:• Fluvial processes (Morphology and morphodynamics; Bed forms and flowresistance; Over-bank flow and vegetation; Interaction with structures;Sediment supply, entrainment and transport);• River hazards (Dam break and fast transients; Bank failure; Floodpropagation; Hyper-concentrated flows; Water pollution and contaminanttransport);• Hydraulics for river management (River training and restoration; Habitatmanagement and maintenance flows; Flood management and control;Integration of telemetry and GIS). As the editors of the Conferenceproceedings we acknowledge the members of the International ScientificCommittee for the in-depth reviewing of the manuscripts. The 70% of theaccepted papers have been selected for oral presentation (123), while the30% have been evaluated as more appropriately presented in the postersession (49). All the accepted papers have been included in this volume.A grateful acknowledgment is deserved to all the members of the LocalOrganizing Committee for the intense work related to Conferencepreparation. Finally we acknowledge the Federico II University of Naplesthat was strongly involved in the success of River Flow 2004 for hosting theConference, and the various sponsors for their financial support.

Accompanying Person Program

The accompanying persons will share the O’ Sole mio Welcome Cocktail

and the Conference Banquet with the conference attendees. A visit to

Naples - Old City will be included in the Registration Fee. The visit will make

you discover the Naples old town, whose main streets where built over

ancient greek and roman streets during centuries. Here you can taste, also

at lunch, the famous neapolitan pizza. "Castel dell'Ovo" and "Maschio

Angioino" are also included in the visit.

Additional entertainment programTransfers, english speaking guide, tickets and dinner are included in tour

prices. Single tours will be cancelled if participants are less than 25. Contact

the secretariat for reservation.

PompeiThe delightful visit to Pompei ancient town, with transfer included from and

back to Naples, will take the entire day with an english/italian speaking

guide. We will have lunch in the exclusive restaurant inside the archeologi-

cal site of the Ancient Pompei.

CapriWe will live from Molo Beverello in Naples by hidroplane; arrived to Capri we

will go in the famous “piazzetta” directly and have a look of the small alleys

all around. Then we will go to visit, with an english/italian speaking guide, the

“Grotta Azzurra” one of the most evocative places in Capri.

Also known as “Gretola”, it was re-discovered in 1826 by the german pain-

ter August Kopisc. The trip to reach the “Grotta Azzurra” is really striking too:

we will make it on small motor boats leaving from the little harbor and then

we will use smaller local boats to entry in the cave. We will have lunch in one

of the small restaurants nearby the famous “piazzetta”.

In the afternoon it’s foreseen the visit to “Villa Damecuta”: one of the 12 hou-

ses built by the roman emperor Tiberio during the I century a.C., re-disco-

vered between 1937 and 1948, and to the “Torre Damecuta” a cylindrical

tower built during XII century a.C. against pirates. We will be back to Naples

for dinner.

IschiaWe will live from Molo Beverello in Naples by hidroplane; arrived to Ischia

we will take a tour using small bus along the tortuous roads of the island,

between wonderful landscapes and a blooming nature. We will have a fresh

fish base lunch in one of the tipical restaurants. In the afternoon we will visit

Roman baths, gardens and caves. Then, before coming back to Naples for

dinner, we will visit the Soccorso church, which, with it’s white structure,

Tourist Information"Naples is paradise: Here it seems as if I were a totally different person and

I am hardly able to recognise myself… In Rome, I was happy studying: but

here I want to live and forget about myself and the rest of the world. It is a

very strange experience finding myself in a society in which no one does

anything but enjoy themselves…".

W. Goethe

"In Europe, there is nothing, I wouldn't say that resembles, but that even

remotely gives an idea of what I am experiencing… I find very little time for

writing, perhaps because Naples, like Paris, is a great capital."

H.B. Stendhal

"With the exception of the glaciers, Vesuvius is the most impressive exam-

ple of the force of nature that I have ever seen."

P.B. Shelley

The largest city of Campania, capital of the province and the region, Naples

is the third most populated city in Italy (after Rome and Milan), with over a

million inhabitants, and is the most important industrial centre and trading

port for the South. It is situated halfway down the Tyrrenia coast, at the inner-

most point of the Bay of Naples, between Vesuvius and the Phlegrean

Fields. In the vast urban area one can distinguish many different neighbour-

hoods: the old centre, characterized by buildings closely crowded together,

is bordered on the west by the new administrative district and on the east by

the business district, into which flows almost all the road and rail traffic.

Other neighbourhoods, with narrow climbing streets, rise around the base of

the San Martino and Capodimonte hills.

12


Historical BackgroundThe original nucleus of the city can be found on the little island of Megaride.

Occupied today by Castel dell’Ovo, it was first a settlement of the Aegean

Greeks, then the Rodi, followed by the Cumani, in the seventh and sixth cen-

turies B.C. The Cumani also occupied the Pizzofalcone heights and named

the city Palaepolis (Old City).

Around the fifth century B.C., Neapolis (New City) arose in the surrounding

areas, exercising strong cultural influence based on its Greek roots.

The mythical tomb of Parthenope, a siren, was supposedly at the site where

Naples grew up. As a result, the city has become known as Parthenopaea.

Under the rule of the Roman Empire, the city of Naples enjoyed economic

and cultural prosperity.

The area became popular for holidays due to its beautiful coastline. Luxury

thermal spas sprung up around Naples which became famous throughout

the empire and which attracted politicians and intellectuals such as Cicero

and Virgil. Later it was occupied by the Byzantines, then the Goths, and then

became capital of an autonomous dukedom.

After a brief period of Longobard dominion, it fell under Norman control, until

Ruggero II of Altavilla, King of Sicily, was able to add it to his kingdom in

1139. With the Angevin conquest in 1266, Naples became the capital and

experienced notable demographic and urban growth.

New growth occurred with the arrival of Alfonso of Aragon and with the reign

of his successors (fifteenth century). After Charles VIII of France, the

Spanish took over in 1503. Naples rose to the dignity of being a capital again

in 1734 under the Bourbons, who reigned there until September 1860

(except during the brief French parenthesis, 1806-1815), at which time it

was annexed to Garibaldi’s Italy.

The bombardments of the Second World War, aggravated by the resistance

of the German troops, caused death and destruction to the patrimony of

population and of art.

UniversityRiver Flow 2004 will be hosted by the University Federico II, located in

Naples, Italy. The University bears the name of its promoter on June 5th

1224, Frederick II Hohenstaufen, King of Sicily and Head of the Roman

Empire. The number of enrolled students and that of the teaching staff have

made of the University of Naples one of the largest Universities in the

country. The Conference venue of Agnano is a structure recently opened for

teaching by the Faculty of Engineering.

Monuments

Chiesa San Domenico MaggioreThis Gothic church was completed in 1324 by the Dominican order and was

much favoured by the Aragónese nobility. The church's interior, a cross bet-

ween Baroque and 19th-century neo-Gothic, features some fine examples

of Renaissance sculpture. In the sacristy are 45 coffins of the princes of

Aragón and other nobles.

DuomoThis grand cathedral was built on the site of earlier churches, which were

themselves preceded by a temple to the pre-Christian god Neptune.

Construction of the cathedral kicked off in 1272 under Charles I of Anjou.

Inside, above the wide central nave, is an ornately decorated coffered ceiling.

Museo Archeologico NazionaleThese archaeological treasures form one of the most comprehensive col-

lections of Greco-Roman artefacts in the world. The musuem houses a rich

collection of antiquities, including treasures that were discovered at Pompeii

and Herculaneum. It also contains the Borgia collection of Etruscan and

Egyptian relics.

Palazzo RealeFacing the grand Piazza del Plebiscito, this magnificent palace, built around

1600, was completely renovated in 1841 and suffered extensive damage

during WWII. The statues of the eight most important kings of Naples were

inserted into niches in the facade in 1888.

Palazzo Reale di CapodimonteWork on a new palace for Charles of Bourbon started in 1738 and took

almost a century to complete. Extensively restored during the last decade,

the palace houses the Museo e Gallerie di Capodimonte, which displays the

important Farnese collection. The extensive holding boasts works by Bellini,

Botticelli, Caravaggio, Correggio, Masaccio and Titian.
