kariba dam wall collapse

“We’re looking at a fifteen- to twenty-year process, in which we are five years under way.” To repair the dam, workers will enlarge the plunge pool downstream, to reduce erosion near the foundation. • It took up to three years for the dam wall to be completed. We need to develop a national mindset that accepts these realities and engenders solutions5. Dam owners must develop and maintain mature dam safety management programs which are based on a strong “top-down” dam safety culture. A critical review of these processes in dam safety practice is warranted, comparing their strengths and weaknesses with risk assessment processes used in other industries worldwide and by other federal agencies.

Go and research from Zambia River Authority on what the two government are doing to save the dam from collapsing.“The dam safety culture and program within DWR … was still relatively immature at the time of the incident and has been too reliant on regulators and the regulatory process.”Bottom lineAs the report succinctly states:Here in Zambia we also have an ageing dam with structural problems not envisaged when the dam was planned and built. The dam foundations are very sound. In February 2017 an overflow spillway on a major dam, the Oroville Dam in California, collapsed and disaster was narrowly averted. You obviously did not read it. Kariba’s collapse, like Mosul’s, would constitute an epochal event in the history of energy development—the dam industry’s Chernobyl. The erosion had under-cut and destabilised the wall, putting the structure at high risk of collapse. Following on the heels of the reported near collapse of the incomplete Tokwe Mukorsi dam in Zimbabwe, a certain degree of confusion surrounds the condition of the Kariba Dam on the Zambezi River, the largest river in southern Africa. “The Kariba Dam is in a dangerous state. “When you have World Bank and EU as your partners, it is a very thorough process and therefore it will take more time.”“If nothing is done, the dam will collapse in three years,” Darbourn warned in her report.In a report titled Kariba Dam and Power Crisis: The Cost of Poor Management, Greg Mills, the head of the Johannesburg-based Brenthurst Foundation, which has a global network of top analysts, pointed out that excessive use of water by both Zesco and ZPC is the reason for the current major power crisis in Zimbabwe.The World Bank, which has organised the funding for the rehabilitation of the dam, does not share the view proffered by the two organisations that Kariba Dam is on the brink of collapse that could plunge the region into a major power deficit.However, the rehabilitation of Kariba Dam, which was supposed to begin last year and is expected to cost US$294,2 million, has not yet taken off with expectations that it will now begin next year. The wall of Kariba Dam, one of the world’s largest dams measuring 128 meters tall and 579 meters long, has developed weaknesses and may collapse if nothing is done to repair it in the next three years, the report said. They are:1. It says “A summary of the reports findings has been written by Elizabeth Ingram of Hydroworld.com”. More frequent physical inspections are not always sufficient to identify risks and manage safety.Shut up you are just trying to justify another expensive loan!“… DWR has been somewhat overconfident and complacent regarding the integrity of its civil infrastructure and has tended to emphasize shorter-term operational considerations … [resulting] in strained internal relationships and inadequate priority for dam safety.”2. The name Kariba (Kariva – meaning trap) refers to a rock which thrust out of the swirling water at the entrance to the gorge close to the dam wall site, now buried more than a hundred feet below the water surface. The plunge pool extends to within a hundred and thirty feet of the dam’s foundation; if it reaches the foundation, the dam will collapse. A report investigating why this failure to prevent disaster on the Oroville Dam occured has just been published. All is well. If the reservoir fills to a dangerous level, the operators face two options: allow water to flow over the top of the dam and tumble down its face, threatening the foundation, or, more likely, open more than three floodgates, causing the plunge pool to expand. Or have lessons been learned?For once we’ve been proactive. The Kariba Dam is a double curvature concrete arch dam in the Kariba Gorge of the Zambezi river basin between Zambia and Zimbabwe.The dam stands 128 metres (420 ft) tall and 579 metres (1,900 ft) long.
