The Owen Falls was a waterfall on the White Nile in Uganda near the city of Jinja, 4 km from the point at which the river leaves Lake Victoria. The falls, together with the nearby Ripon Falls were submerged in 1954 with the completion of the Owen Falls Dam (later renamed Nalubaale, but still commonly known by the old name) that now accommodates a hydroelectric power station. Owen Falls Station: The Owen Falls Station consists of a concrete gravity dam with a close coupled intake powerhouse unit. It controls the Lake Victoria outflows through a series of 10 turbines and 6 sluices in the dam. When fully opened, 6 sluices provide a spill capacity of about 1200 cumecs. Initially equipped with two 15 MW units, the Owen Falls dam was completed in 1968 with eight supplementary units. The ten power generators were rehabilitated and up – rated to 18 MW in 1990s. Owen Falls Station is operated through the Agreed Curve, so that the outflow from Lake Victoria remains the same as it was before the construction of the dam; when the outflow from the lake was naturally controlled by the rocky barrier of Ripon Falls. The feasibility of increasing the power generating capacity of the Owen Falls complex was studied at the end of the 1980s by ACRES. The proposed extension envisaged the construction of 1 km long power canal just beneath the right or east abutment of the existing dam, with intake and power house on the right bank of River Victoria Nile, on the north end of the power canal. The Owen Falls Extension, called Kiira was built to utilise the excess water being supplied by the sluices of Nalubaale. It is proposed to construct 5 units of 40 MW each. Work on Kiira project started in 1993 and major construction was completed in 1999. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Owen Falls」の詳細全文を読む スポンサード リンク
