由于降水量严重缺乏及不健全的原始记录而在博兹瓦纳的莱索博哥水坝引发出一系列问题。博兹瓦纳的莱索博哥水坝是该国北水南调工程的重要组成部分,水坝开始蓄水十八个月后,蓄水池的蓄水仅仅8m 深,同预计蓄水28m深相比差距甚远。缺水的原因是丰水期的降雨量大大低于平均降雨量。其结果势必会延误整个计划的实施和水坝的交付使用。博兹瓦纳经常遭受变幻莫测暴雨的侵袭,
A series of problems arose in Lesotho’s dam in Botswana, due to a serious lack of precipitation and poor sounding records. Lesotho Bogor Dam in Botswana is an important part of the North South Water Transfer Project in the country. After the dam started impounding for 18 months, the impoundment of the impoundment reservoir was only 8m deep, with the estimated impoundment of 28m Far than the gap. The reason for water shortage is that rainfall during the wet season is much lower than the average rainfall. The result is bound to delay the implementation of the entire project and the delivery of the dam. Botswana is often subjected to unpredictable heavy rains,
