Lecture 4: Sedimentary Structures Produced by Sediment Transport 08.10.2026 59мин

MIT RES.12-003 Fluid Motions, Sediment Transport, and Current-Generated Sedimentary Structures, Fall 2025Instructor: John SouthardView the complete course: https://ocw.mit.edu/courses/res-12-003-fluid-motions-sediment-transport-and-current-generated-sedimentary-structures-fall-2025/YouTube Playlist: https://www.youtube.com/playlist?list=PLUl4u3cNGP60q1Ib4pyz_FBs_lYUPr9MNA detailed exploration of cross‑stratification reveals how sedimentary structures record the history of flowing water and waves. The video explains how bedforms such as ripples and dunes migrate and deposit layers that are later preserved as inclined laminae separated by erosion surfaces, allowing geologists to interpret past flow directions and conditions. It highlights different styles of cross‑stratification—such as climbing ripples, trough structures, and large dune deposits—and shows how their geometry depends on the balance between sediment supply and bedform movement. The discussion also extends to oscillatory and combined flows, introducing complex features like hummocky cross‑stratification and emphasizing the challenges of distinguishing between flow types in the rock record. Overall, the presentation demonstrates how careful observation of sedimentary patterns can be used to reconstruct ancient environments and flow dynamics.License: Creative Commons BY-NC-SAMore information at https://ocw.mit.edu/termsMore courses at https://ocw.mit.eduSupport OCW at http://ow.ly/a1If50zVRlQWe encourage constructive comments and discussion on OCW’s YouTube and other social media channels.

Prof. Southard explains key concepts such as laminar versus turbulent flow, Reynolds number, and dimensional analysis, using classic experiments to illustrate how fluid behavior changes with velocity. The discussion then expands to forces acting on particles, including drag, lift, and the role of viscosity, as well as how flow interacts with boundaries in channels. The lecture also explores oscillatory flows generated by waves, their effects on sediment movement, and how combined flow conditions can become complex. Finally, it examines how sediment begins to move, highlighting factors like shear stress, particle size, and turbulence, and introduces concepts such as the Shields diagram to describe the onset of motion.License: Creative Commons BY-NC-SAMore information at https://ocw.mit.edu/termsMore courses at https://ocw.mit.eduSupport OCW at http://ow.ly/a1If50zVRlQWe encourage constructive comments and discussion on OCW’s YouTube and other social media channels.

Lecture 2: Mechanics of Sediment Transport 08.10.2026 59мин

MIT RES.12-003 Fluid Motions, Sediment Transport, and Current-Generated Sedimentary Structures, Fall 2025Instructor: John SouthardView the complete course: https://ocw.mit.edu/courses/res-12-003-fluid-motions-sediment-transport-and-current-generated-sedimentary-structures-fall-2025/YouTube Playlist: https://www.youtube.com/playlist?list=PLUl4u3cNGP60q1Ib4pyz_FBs_lYUPr9MNIn this lecture, Prof. John Southard continues his exploration of sediment transport by focusing on how sediments move, how transport is measured, and how different flow conditions create distinct bedforms. He explains key concepts such as bedload and suspended load, transport rates, and the challenges of measuring sediment movement in natural systems. The lecture also introduces aeolian (wind-driven) transport, highlighting saltation and the role of density differences between air and water. A major portion is devoted to the formation and evolution of bed configurations—especially ripples and dunes—using both laboratory flume experiments and natural examples to illustrate how flow velocity, sediment size, and turbulence interact to shape the landscape. Southard emphasizes the dynamic feedback between flow and sediment, showing how bedforms both result from and influence fluid motion.License: Creative Commons BY-NC-SAMore information at https://ocw.mit.edu/termsMore courses at https://ocw.mit.eduSupport OCW at http://ow.ly/a1If50zVRlQWe encourage constructive comments and discussion on OCW’s YouTube and other social media channels.

Lecture 3: Bed Forms 08.10.2026 58мин

MIT RES.12-003 Fluid Motions, Sediment Transport, and Current-Generated Sedimentary Structures, Fall 2025Instructor: John SouthardView the complete course: https://ocw.mit.edu/courses/res-12-003-fluid-motions-sediment-transport-and-current-generated-sedimentary-structures-fall-2025/YouTube Playlist: https://www.youtube.com/playlist?list=PLUl4u3cNGP60q1Ib4pyz_FBs_lYUPr9MNProf. John Southard builds on earlier concepts by examining how different flow conditions, sediment properties, and dimensional analysis combine to produce distinct bed configurations such as ripples, dunes, and plane beds. He uses laboratory data and conceptual models to map out how these features vary with flow velocity, depth, and grain size, highlighting patterns like the transition between flow regimes and the presence of spectral gaps between ripples and dunes. The lecture then expands to oscillatory flows and wave-generated bedforms, explaining how ripple geometry changes from two-dimensional to three-dimensional forms and how complex patterns emerge under natural wave conditions. Southard also introduces the added complexity of combined flows, where currents and waves interact, emphasizing the challenges of predicting resulting structures. The session concludes by linking these physical processes to sedimentary structures preserved in rocks, setting the stage for interpreting past flow environments from geological records.License: Creative Commons BY-NC-SAMore information at https://ocw.mit.edu/termsMore courses at https://ocw.mit.eduSupport OCW at http://ow.ly/a1If50zVRlQWe encourage constructive comments and discussion on OCW’s YouTube and other social media channels.
