The Delft Sand, Clay & Rock Cutting Model
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

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.

Dredging Engineering: Special Topics
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

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.

Marine Law and Policy for Scientists and Managers - 1st Edition
Conditional Remix & Share Permitted
CC BY-NC
Rating
0.0 stars

This open educational resource is designed for use by undergraduate and graduate ocean science, natural resource, fisheries and wildlife, and environmental policy students enrolled in a ten-week academic quarter. The purpose of this project is to provide students and non-law professionals with a freely accessible, clearly written guide to support engaging and effective learning. As such, the book serves as a gateway and an invitation to become a well informed, committed and involved ocean citizen as well as to explore the field beyond our course study.
