The Tidal Elbe: The Port of Hamburg

4 The City and Port of Hamburg

• No. 3 in Europe

• 250,000 Jobs in Germany

• 7.9 mio. TEU / 121 Mio. t in 2010

(24 % dedicated to Hamburg region)

• 12.4 mio. TEU in 2015 expected

• Fairway depth 13.50 m*

• Deepening to 14.50 m* on its way* Independent of the tide

maintenance dredging is crucial!

“why?“

10

Estuaries are changing…

20021976

…and are beeing changed


11

Changing Estuary: Land Reclamation and Dykes

>> Today 97% without tidal Influence


12

Changing Estuary: Tidal Range and Measures


~ 1.8 m~ 3.6 m

Changing Estuary: Water Levels 1900 - 2000

Water level in 1900

Water level today


Sea Level Rise?

Changing Estuary: Tidal Pumping


15

Nachteilige Veränderung: Verlandung

Changing Estuary: Sedimentation

1. Taming the Tide through River

Engineering in the Mouth,

2. More Room for the River (Tidal

Volume) in the upper Part

3. Smart Sediment Management

considering the whole Elbe

System

Three Cornerstones:

Helping the Estuary*: The Tidal Elbe Concept

Epilogue: Inland-Seaport saves CO2

Port 130 km inland:

1 Container vessel saves 680 t CO2*!
