Flood protection reservoir (dry polder) of Racibórz Dolny on the Oder River

PROJECT DESCRIPTION:

The Raciborz Dolny Flood Protection Reservoir on the Oder River is one of the key elements of the Oder River Valley flood protection. It is being created under the Oder 2006 Programme, as part of a passive and active flood protection system. The reservoir will reduce the impact of the Oder and Neisse Rivers on the creation of flood waves, which caused severe damages and losses during the great flood of 1997. The impact of the flood protection of the reservoir, along with the Bukow Polder, will reach from Raciborz Town to Wroclaw City.

TECHNICAL DATA:

• the reservoir of an area of 2.626 ha will be able to accomodate 185 million m³ of water in Phase II, and 320 million m³ in Phase III (150 million m³ of usable capacity and 170 million m³ of flood reserve)
• the reservoir will be about 10 km long and 4 km wide
• the reservoir capacity will allow to reduce the flood waters discharge:
  • with 48-hour forecast of inflow to the reservoir – from 3,120 m³/s to 1,538 m³/s,
  • with 24-hour forecast of inflow to the reservoir – from 3,120 m³/s to 1,800 m³/s.

SCOPE OF SERVICES:

• conceptual design
• feasibility study (in Consortium with Jacobs Gibb and Jacob Gibbs Polska)
• hydraulic modelling studies
• preliminary and detailed designs
• EIA report
• update of the designs
