THE discussion which took place on certain notes read before Section I1 of the 1921 Engineering Conference showed that there scheme for " {ockieing" the River Thames above Gravesend. It Are great, if not insuperable, objections and difficulties t o any follows that the whole of the River Thames from London to the sea is likely to remain tidal water for an indefinite period. Apart from the great traffic dealt with in the London Docks, there will, however, remain the subsidiary problem of establishing tidal deepwater quay? in the open river. undertakings proposed from time to time has been actually carried Although, with one exception, none of the more comprehensive out, there has been steady development in the construction of deep-water quays for special trades; and the firm of which the Author is a member has, since the War, been responsible for the design of three such quays-one completed and two under construction at the present time-and is also interested in the maintenance of several similar undertakings. Thames, t o berths for shipping of up to 20,000 tons dead weight, This Paper is restricted to the results of experience on the and to quays having a depth of water varying hetwcen 10 feet and the Paper the subject is dealt with under t w o headings, namely :-32 feet at low water of ordinary spring tides.

Considerations of Design.-That the subject of dcsign is of great importance may be judged from the fact that post-war work in the River Thames has cost from f l O O t o over E200 per lineal foot of quay. These figures are in themselves of little value, as it is nevcr possible to make any real comparison of cost between one deepthey are of interest as showing how high prescnt-day (1920-1921) water quay and another, unless the conditions are identical; but Downloaded by [ University of Liverpool] on [15/09/16].
