Stream Table 2011

This course was last taught Winter 2011. That semester, research was conducted using a small (~0.5 X 1.5 m) commercial table with limited capabilities. The goal was the same, to create a sustainable migrating meander and was accomplished on a limited basis (i.e. a single migrating meander bend near the head of the table). Toward the end of the semester, the 2011 group developed ideas for what they called the "Dream Table." In conjunction with the Department of Mechanical Engineering at BYU-Idaho, a preliminary version was constructed and used for the first time this semester (Winter 2013).

BYUI Undergraduate Research Conference Abstract: BYU-Idaho Department of Geology Stream Table Modifications

Abstract submitted for poster presentation at the BYU-Idaho Student Research Conference

BYU-Idaho Department of Geology Stream Table Modifications

Joseph McCullough, Tim Melton, and William W. Little (mentor)

The BYU-Idaho Department of geology through its course in geomorphology is involved in research utilizing a stream table to model natural fluvial and marine processes. To date, a small (~0.5 x 1.5 m) commercial table that consists of a box for sediment, a water pump for stream discharge, and an adjustable pipe to control base level has been used. This was found to be inadequate for continued research. Other commercial tables also lack desired features, such as a sediment feed mechanism, variable discharge, and basin subsidence capability. Therefore, a larger table (~1.2 x 2.4 m) was designed by the Department of Geology and constructed as a senior project through the Department of Mechanical Engineering. Use of the new table has indicated a need for further adjustment to some components. Encountered problems include: a leaky hinge associated with the stream gradient adjustor,  wicking of moisture into the sediment feed; stalling of the sediment feed at very low turn rates, sticking of the base-level controlling unit; and inadequate camera mounts. This poster illustrates proposed solutions to these issues.
