DREDGING PERFORMANCE, YIELD AND EFFICIENCY
The Author describes the studies being undertaken on the River Clyde to quantify the performance of the maintenance dredging plant together with some of the methods adopted to improve the plant efficiency. Monitoring of the sediment inflow is described as is the rate of deposition and the variation in bed level with time. The use of the Harwell Silt Density Probe for both in-situ measurements of sediment density and in hopper measurement is described. A method of determining the efficiency of the dredging operation is proposed, based on knowledge of the different average sediment densities. Existing methods of measuring the output of dredging plants and dredgers are reviewed and measures for improving their efficiency are suggested. Where the quantity of material dredged is to be compared with the quantity entering the estuary system, the EXPRESSION OF THE OUTPUT IN TERMS OF DRY SOLIDS IS considered to be the only suitable solution.
