The Basingstoke Canal Aqueduct S. Al-Shawaf, BSc, MSc, DIC, MICE, MIStructE, and P. Jacobs, CEng, MICE The Basingstoke Canal Aqueduct was constructed as part of the 130 million Blackwater Valley Route dual carriageway, which now links the A30, M3 and A31. The aqueduct formed part of the centre and last contract of the route to be let and was completed in June 1995 following a 9 month closure of the 200 year old historic canal. The award-winning project incorporates many innovative design concepts, a sympathetic style and high quality of workmanship...

Proceedings.] BARNETT ON REPAIRING AN AQUEDUCT. 153 (Paper No. 3636.) `' Repairing a Limestone-Concrete Aqueduct." By MICHAEL RATCLIFFE BARNETT, Inst. C.E. M. HAVING engaged in investigating the cause of and inremedying been leakage from a waterworks-culvert built of concrete made with broken limestone, the Author believes that a record of the work may be of interest, as the leakage was found to be due to deterioration of the concrete, resulting from the action of the soft water flowing through the aqueduct on the limestone with which the concrete was made...

BLACKADDER remarked that the Author had developed ;Ldder, Mr. Blnckand put into practice a result of the general law of flow of water in long pipes in which the head used to generate kinetic energy due to the speed of the water, or in other losses such as those of valves or cross-overs, was negligible in comparison with frictional losses...

EDINBURGH'S FIRST WATER SUPPLY Edinburgh's first water supply: the Comiston Aqueduct, 1675-1721 E. H. Winant, MSCE, PhD and E. L. Kemp, PE, PhD The 18th century saw a tremendous advance in the number and effectiveness of hydraulic theories. These advances are clearly seen in the design of 19th century water supply projects, such as the Croton Aqueduct in New York. But earlier failures in hydraulic design showed the need for new theories. This paper recounts the development of the Comiston Aqueduct in Edinburgh as a much discussed design failure that helped to trigger new research into hydraulic design...

D.Sc., INthis Paper, the Author presents a description of the methods adopted in setting out two tunnels, one 43 miles, and the other 23 miles in length, on the aqueduct of the Elan Water Supplyof the Birmingham Corporation. Thetunnels were driven 9 feet 6 inches in height and 9 feet in width, and the various headings met between 15 April, 1898, and 27 January, 1899...

The AUTHOR remarked thatFig. 3 had been prepared in the first instance to show clearly the flows measured with a single main up to each cross-over, and double main beyond. In the Paper he had mentioned that it was immaterial where the single main was, and whether it was in one or more pieces ; but he had not shown any justification for that statement. He had, therefore, open had flows obtainedinlengths circles puton Fig...
