In this unit we use a chemical weathering example to illustrate 1) how physical processes and geochemical processes are coupled, and 2) how to set up physical and geochemical processes in a 1D column in Crunchflow. In essence the set up is a combination of mineral dissolution and precipitation discussed in lesson 2 and physical processes discussed in lesson 6. Please review these two lessons if necessary.
By the end of this lesson, you should be able to:
- Understand the importance of chemical weathering;
- Understand the fundamental principles and key parameters that govern chemical weathering and reactive transport process coupling in general;
- Set up simulations in Crunchflow with flow, solute transport, and mineral dissolution and precipitation reaction.
