Students use a small stream table in groups to investigate how channel form determines the shape of the hydrograph (including lag to peak). They use three channels: no channel (just sediment filling the table), a "concrete" channel (straight, no sediment on bottom), and a meandering channel. All channels get the same water input and students measure the amount of water that comes out to make a hydrograph. This gives students a chance to model a flood pulse moving through different channels to see how anthropogenic changes to rivers, such as channelizing them, alters flood hydrology. It specifically models an outburst flood from a dam release or burst, but is basically modeling any pulse of water moving through a system.
This class serves as an introduction to mass transport in environmental flows, with emphasis given to river and lake systems. The class will cover the derivation and solutions to the differential form of mass conservation equations. Class topics to be covered will include: molecular and turbulent diffusion, boundary layers, dissolution, bed-water exchange, air-water exchange and particle transport.
In summary, "The Varied Landscapes of the Colorado Plateau" provides an engaging overview of the geological and geographical marvels found in this region of the United States. From ancient rock layers to stunning natural formations, the Colorado Plateau's landscapes continue to captivate and inspire those who explore its diverse terrain.
The best way for students to understand how groundwater flows is to actually see it. In this activity, students will learn the vocabulary associated with groundwater and see a demonstration of groundwater flow. Students will learn about the measurements that environmental engineers need when creating a groundwater model of a chemical plume.
