2 72 JENNINGS' SLUICE VALVE. The system introduced by Mr. Barrett appeared to merit the attention of both engineers and architects, as there were numcrouspositions to which it was admirably adapted. He hoped that the subject wouldbefollowedby a more comprehensive paper on fire-proof buildings generally. JENNINGS' SLUICE VALVE. After the meeting, one of Jennings' Sluice Valves was exhibited in the ante-room. The improvement was stated to consist in simplifying the construction, by casting the "body" and the ``faucet" ends in one piece, thus avoiding the use of bolts, nuts, and joints...

(Ordered by the Council to be published in abstractform.)] T H Author points out that the flow through open-type river-regulating ~ sluices is subjeot to periodic impulses. The occurrence of these impulses is objectionable, as they may endanger the safety of the sluice-structure in any of the following ways :( a ) Whilst the water-level is at its crest in one sluiceit is a t its lowest in the next sluice, thus subjecting the dividing pier to alternating side pressures which it was not designed t o resist...

Scour downstream of aprons caused by sluices

Authors: A. Sarkar, S. Dey

Source: Proceedings of the ICE - Water Management, Volume 158, Issue 2, June 2005, pages 55 - 64

The characteristics of scour holes in uniform and nonuniform sediments downstream of an apron due to a submerged horizontal jet issuing from a sluice opening are studied experimentally. Attempts are made to explain the similarity existing in the scour profiles (including the dune downstream of the scour hole). From the scour profiles, the characteristic lengths of the scour hole which are determined are: horizontal distance of dune crest from the edge of the apron; dune height; horizontal distance of maximum scour depth from the edge of the apron; horizontal extension of scour hole from the edge of the apron and maximum equilibrium scour depth. For uniform sediments, the horizontal distance of the dune crest from the edge of the apron, the horizontal distance of maximum scour depth from the edge of the apron, the horizontal extension of scour hole from the edge of the apron and the maximum equilibrium scour depth were all found to increase with increase in densimetric Froude number; whereas the dune height decreases with increase in densimetric Froude number. In addition, for nonuniform sediments, the aforementioned characteristic lengths of the scour hole are related to the geometric standard deviation of sediments. The characteristic lengths of the scour hole decrease with an increase in geometric standard deviation of sediments. The application of the findings of the paper to the prototype is discussed, which would assist the practising civil engineer to ascertain the dimensions of a scour hole (scour depth, position of maximum scour depth, extension of scour hole etc.) in uniform and nonuniform sediments downstream of an apron. Importantly, these are the key parameters for designing apron foundations and protective measures for scour downstream of an apron. Future work will focus on field work to prove the scalability of the derived relationship.

Is the tidal canals hitherto constructed in Bengal, the filling has been effected during high tides, and through the locks, the gates of which opening towards the canal admit the river-water, when the tide rises higher than the water impounded in the canal. But in the case of the coast-canal, now under construction, the locks have reverse gates on the river side for the exclusion of the tide, t h e filling being effected through sluices, between which and the canal are channels, from 1 mile to 2 miles in length; this arrangement is adopted in order that all the silt, which comes in with the tidal water, may be deposited before it reaches the canal proper...
