| Description: | Technical Report Abstract: Report describes full-scale tests of patented, air-operated solids handling device called the PNEUMA pump. The pump was tested in a river channel, lock entrance, tidal inlet, and dock area in both sand and fine-grained sediment. The report describes test procedures, equipment, instrumentation, and data reduction. Results are evaluated in terms of pumping performance and turbidity generated in fine-grained sediment. The pump could dredge in situ densities in fine-grained sediment but could not in sand. Difficulty was experienced in sustaining high discharge densities. Power efficiencies of pump were low. No significant turbidity was measured when dredging fine-grained sediment. Appendix A gives graphical presentations of performance parameters for each test run. Appendix B presents tables of measured turbidity values. Appendix C (bound separately) contains tables of measured data and calculated parameters interpolated at 9-sec intervals for each test run. |
