Piano Key Weir on Malarce dam (EDF – France)

Welcome On behalf of the National Hydraulics and Environment Laboratory and the Hydro Engineering Center of Electricité de France, of the Research Group on Hydraulics in Environmental and Civil Engineering of the Université de Liège, and of the Laboratory of Hydraulic Constructions of the Ecole Polytechnique Fédérale de Lausanne, we warmly welcome you to the second International Workshop on Labyrinth and Piano Key Weirs in Chatou (Paris).

4 keynotes lectures and around 30 technical papers from 5 continents will be presented by people with varied background (engineers, researchers and academics) to state and summarize the current knowledge on Labyrinth and Piano Key weirs. Significant time will be devoted to discussion in an environment willing to be friendly, co-operative and non-competitive. Social and technical events including a guided tour in the EDF R&D’s Hydraulics and Environment Laboratory, a sightseeing boat trip on the Seine River and a visit of the Malarce dam will offer the opportunity for participants to meet and share as well as to discover France.

We wish you a pleasant and fruitful workshop.

General information

Venue The workshop will be held at the Research & Development center of Electricity of France, in Chatou near Paris (France). EDF site address: 6, Quai Watier – 78401 Chatou.

Getting to Paris and local travel Paris is easily accessible by plane, train or car. Main international airports are Paris-Charles de Gaulle and Paris-Orly.

Local travelling is offered by RATP (www.ratp.fr). The hotels and the workshop venue can be easily reached from downtown Paris by Metro or RER Train.

To facilitate transportation to the workshop site, transfers by bus will be organized for all workshop participants on Wednesday, November 20th, and Thursday, November 21st, between hotel Holiday Inn Paris Bastille (located : 11 rue de Lyon, 75012 Paris, near “Gare de Lyon” RER station, see map under “Accommodation”) and the EDF site. Departure of the bus at 7:00 AM, arrival on the workshop site around 8:00 AM. Participants wishing to reach the workshop site on their own can use the public transportation network (Metro and RER). The workshop venue can be easily reached from downtown Paris (about 45 mn) by RER A (red line), direction “Saint-Germain-en-Laye”. Go down to “Rueil-Malmaison” station (NB: avoid “Chatou” station, which is further access to the site). From “Rueil-Malmaison” station, you can either take a shuttle or walk. See details below.

• Regular shuttle (line 4E) connects the RER station and the EDF site (about 5 min ride). To reach the shuttle stop, when you exit the RER train, use the exit located on the center of the platform (Exit n°5 – Avenue Victor Hugo), see map above. Bus schedule:

o RER station to EDF: 07 h 52, 08 h 06, 08 h 26, 08 h 52 o EDF to RER station: 16 h 32, 17 h 02, 17 h 22, 17 h 42, 18 h 02

• To join EDF by walk (about 15 min) from the RER station, use the exit located at the

head of the train, go down the stairs and turn right towards « Rue des deux gares » exit. After exiting the station, proceed to “Avenue de Colmar” in the direction of Chatou. On the middle of the bridge, turn right to the slip road, going to the “île des Impressionnistes”. See map below, showing the walking itinerary in red.
