In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.

In this enlightening lecture, Dr. Ayana Omilade Flewellen, a distinguished professor at Stanford University, explores the intersections of black feminism, archaeology, and storytelling. She advocates for the centrality of black women's experiences in historical narratives and discusses the multifaceted role of archaeology in public history and cultural preservation. The talk features her work with the Society of Black Archaeologists and Diving With a Purpose, emphasizing the need for diversity in the field and the significance of underwater archaeology in heritage conservation. Dr. Flewellen also presents the Estate Little Princess project in St. Croix, a groundbreaking initiative combining terrestrial and underwater archaeology to uncover and preserve Afro-Crucian history. The lecture is a compelling call to recognize and engage with the rich, often untold, histories that shape our world, making it a valuable resource for students, educators, and anyone interested in the dynamic fields of archaeology and cultural heritage.

In dredging, production estimating is carried out mainly with analytical physical models of the different dredging processes. Slurry transport of settling slurries and cutting processes in sand, clay and rock are already covered in two other books by the author. Other processes like hopper sedimentation and erosion, water jet fluidization, cutter head spillage, pump/pipeline dynamics and clamshell dredging are covered in this Special Topics Edition. New topics may be added in the near future.
