Available in PDF, EPUB and Kindle. Book excerpt: Behavior of dredged clay lumps varies widely depending upon their geotechnical characteristics. Predicting the behavior of clay lumps in important in estimating the difficulties associated with the transporting phase of dredged materials. Existing engineering soil descriptors are not oriented towards dredging operations and therefore cannot be used for accurate behavior predictions. Usage of these predictors in practice often leads to disputes between the parties involved in the dredging project. This work presents the empirical relationship between basic clay properties and the degradation rate of clay balls being hydraulically transported. Various clay consistencies were simulated in the laboratory using different proportions of kaolinite and bentonite in mixture. These clays were then statically compacted to different degrees of density relative to their maximum standard Proctor dry density. To simulate the hydraulic transport effects, samples were subjected to two types of tests. In the first one, clay samples were clamped and lowered underwater and were spun for different times and velocities. The remaining intact portions of the samples were then dried and weighed to determine the effect of relative movement of water against the clay. In the second test, clay samples were placed in a drum, partially submerged in water.

Book excerpt: This technical note presents results obtained from test conducted on synthesized clay balls and on clay balls from Mobile Ship Channel subjected to a simulated environment similar to hydraulic transport conditions. work was conducted under Dredging Research Program (DRP) Technical Area 2, Material Properties Related to Navigation and Dredging. Based on these results, empirical relationships between degradation rate and the clay's plasticity and density (or stiffness), as well as the ball's average transport (drag) velocity, are established.

Available in PDF, EPUB and Kindle. Book excerpt: Laboratory experiments with compacted kaolinite-bentonite mixtures indicate that degradation of hydraulically transported clay lumps in a dredge pipeline can be predicted and controlled to some extent. The size reduction of these lumps depends not only on the length of the pipeline but also on the density of the clay being dredged, the plasticity index (PI) of the clay, and the velocity of the dragging slurry in the pipe. A series of graphs shows percent reduction in clay lumps as a function of PI and velocity at three levels of relative compacted density.

Download or read book Hydraulic Fill Manual written by Jan van 't Hoff and published by CRC Press. This book was released on 2012-12-18 with total page 674 pages. Available in PDF, EPUB and Kindle. Book excerpt: Without proper hydraulic fill and suitable specialised equipment, many major infrastructure projects such as ports, airports, roads, industrial or housing projects could not be realised. Yet comprehensive information about hydraulic fill is difficult to find. This thoroughly researched book, written by noted experts, takes the reader step-by-step through the complex development of a hydraulic fill project. Up-to-date and in-depth, this manual enables the client and consultant to understand and properly plan a reclamation project. It provides adequate guidelines for design and quality control and allows the contractor to work within known and generally accepted guidelines and reasonable specifications. The ultimate goal is to create better-designed, more adequately specified, and less costly hydraulic fill projects.
Download or read book An Introduction To Hydraulics Of Fine Sediment Transport written by Ashish J Mehta and published by World Scientific Publishing Company. This book was released on 2013-09-30 with total page 1060 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents observations on the phenomena of fine sediment transport and their explanations under process-related divisions such as flocculation, erosion, and deposition.The text is a compilation of the author's lecture notes from nearly four decades of teaching and guiding graduate students in civil and coastal engineering. Illustrations of fine sediment transport processes and their complexities given in the book are taken from field and laboratory-based observations by the author and his students, as well as numerous investigators.The wide-ranging composition of particles (of inorganic and organic matter), their universal presence and their complex interactions with hydraulic forces make this branch of science a difficult one to deal with in a single treatise. It is therefore essential to study fine sediment transport as an independent subject rather than cover it in no more than a single chapter as many texts on coarse sediment transport have done.Even though the entire coverage is “introductory”, the twelve chapters collectively include more material than what can be reasonably dealt with in a one semester, three-credit course.The book includes an extensive description of the components of fine-grained — especially cohesive — sediment transport. It covers the development of the subject in scientific and engineering applications mainly from the 1950s to its present state. Solved examples and chapter-end exercises are also included.This text is aimed at senior civil engineering undergraduates and graduate students who, in the normal course of their study, seldom come across the subject of fine sediment transport in their curricula. Interested students should have a basic understanding of the mechanics of fluid flow and open channel hydraulics.
