Dam failure analysis sought for Africa’s Zambezi River

The Zambezi River Authority (ZRA) invites expressions of interest from consultants to perform a dam failure analysis for dams and hydropower projects on Africa’s Zambezi River. Responses are due October 4.

ZRA, which is jointly owned by Zimbabwe and Zambia, has applied for World Bank funding to construct the 1,600-MW Batoka Gorge hydroelectric development project on the border of the two countries. Among other major hydropower projects in the multi-national river basin are 900-MW Kafue Gorge and 750-MW Kafue Gorge Lower and 2,040-MW Cahora Bassa, which is located in Mozambique.

ZRA invites expressions of interest from consultants to perform a detailed dam break analysis to assess the potential consequences of a partial or full dam breach at one or several dams in the Zambezi basin. Work is to include analysis of potential flood hydrographs from plausible dam breach scenarios, routing of such floods through downstream river stretches to assess impacts and potential damage or breaching of downstream dams, topographical surveys, and production of flood inundation maps.

Expressions of interest, and qualifications, are due in person, by mail, fax, or e-mail, to both addresses below by 4 p.m. October 4. ZRA plans to compile a short-list of firms to be contacted.
