Activities (3)

Mass Wasting and Slope Stability part of Cutting Edge:Geomorphology:Activities
An investigation of mass movements along the shores of Lake MI. Students will assess strength characteristics of unconsolidated sediment in the field, survey the morphology of the movement, and determine the frequency (or rate) of mass wasting in this area using aerial photography. They will use the field and laboratory data to formulate hypotheses on the type and cause of the failure.

Soil Field Descriptions and Soil Forming Processes part of Cutting Edge:Geomorphology:Activities
This assignment covers the basic techniques of soil descriptions in the field using a modified version of the NRCS Field Book for Describing and Sampling Soils (2002). Students investigate soil profiles at locations that differ in their vegetative cover and topographic position. They then make comparisons between these pits to infer the influence of topography and vegetation on soil formation processes.

Discharge and Sediment Transport in the Field part of Quantitative Skills:Activity Collection
In this quantitative field activity, students collect field data on channel geometry, flow velocity, and bed materials. Using these data, they apply flow resistance equations (Manning and the depth slope product) and sediment transport relations (Shields curve) to estimate the bankfull discharge and to determine if the flow is sufficient to mobilize the bed. This activity requires students to utilize theoretical and empirical equations derived in class in the context of a field problem.One should allow for 2 hours in the field and assume an additional 2-4 hours of student work outside of class

Course

Physics of the Earth: Surficial Processes part of Cutting Edge:Course Design:Goals Database
In this course, we explore the physical and chemical processes responsible for moving sediment and water from mountaintop to ocean bottom. For most of the course we will use a simple balance between driving and resisting forces to determine movement. In most environments rivers are the primary agents of landscape formation, so we will focus on these processes. We will also consider how anthropogenic activities modify natural processes.
