This module considers sediment in the environment from small-scale to global-scale processes. At the small scale you will learn how to characterise sediments and the fluids that transport them. At the global scale you will learn about the main environmental drivers of sediment transport, including rivers, waves and tides. We will consider the importance of sediment as a habitat and how the presence of organisms and biological substances influences sediments. You will learn about the key characteristics of sedimentary environments in both modern and ancient times. We will consider sediment as a global resource and the implications for sustainable management.
