8 Conclusion The increasing number of vehicles, turn over in Emden-Port via several berths has asked in 1999 to built a new pier at the banks of the Ems-River. A new pier with a total length of 350 m with the possibility to lengthen it to 550 m was planned. A very sophisticated planning procedure follows this demand. It was allowed to built the pier, but several data needs to be approved. The most important demand was to forecast the sedimentation and erosion rate in the Ems-River estuary. At one side the University of Darmstadt (Institute for Hydraulics) and at the other side the University of Applied Science in Bremen was asked for model tests and for monitoring. The forecast given by TIMOR3 means a forecast of confidence, because each one in the planning process has had enough information for his questions and his detailed situation. Each one has given its best, but it needs to accept a lot of several marginal conditions. In this special case we have found out that to build the Ems-Pier will be less expansive than to loose some hundred thousands cars to ports of Bremerhaven or Zeebrugge. In each case it needs to calculate profit and costs and the most profitable harbour will be the winner for the next year. But the success of a ports in turnover or ports throughput is very often the result of a world wide connection of a few shipping companies. The port authorities must follow the development of the vessels and the demands of the shipping companies, if they will withstand the very hard competition against the other ports. 9 References Clasmeier, H.D., D.
