T M for Lock/Dams on Inland Waterways
Abstract: Following a brief description of the prefabricated floating PowerBarge concept, the range of application and expected cost and time savings is presented. Environmental benefits are described as increases in dissolved oxygen content due to withdrawal of surface water at the siphon intake; and reduction in entrainment and entrapment of migrant and resident fish due to reported shadow effects and resistance to upward flow. A description is presented of the proposed 700 KW demonstration project to be installed at the New Kernsville Dam on the Schuylkill River for start-up prior to the end of 1991. Preliminary designs of representative Lock/Dam projects are shown in sketch form for multi-unit installation that will maintain more uniform discharge across the width of the river downstream of the dam. Operational access needs are limited to provision for personnel and maintenance supplies. Transportation of units to the site will be by waterway. Descriptions and sketches show the proposed method of installation by use of derricks mounted on the upstream and downstream barges in order to assemble the penstock connection.
