Estimation in Sedimentary Geology: Getting Students Comfortable with Rough Calculation of Rates and Magnitudes part of Cutting Edge:Sedimentary Geology:Activities
The theme of this module is that the most important quantitative skill in sedimentary geology is not complex mathematics but rather a habit of approximate but accurate quantitative thinking. The most useful tool is the ability to make reasonable order of magnitude estimates based on a sense of the magnitudes of important quantities like settling velocity, river slope, subsidence rate, etc. We discuss practical estimation methods based on field observable quantities like grain size and flow depth, as well as methods for applying general geologic knowledge (e.g. rates of plate motion) to estimation of important quantities in sedimentary geology.
Understanding and Applying the Exner Equation part of Cutting Edge:Sedimentary Geology:Activities
The Exner equation lends itself readily to visualization and physical examples; it is far more important in quantitative sedimentary geology than the usual topics from fluid mechanics that are included in undergraduate sedimentary geology texts. We will look 'under the hood' of the Exner equation and discuss what its terms mean and how to present it to undergraduates with emphasis on building intuition rather than mathematical solution methods.
