Summary:

## Snow Layer Combination and Subdivision

After determining the snow temperature, hydrology, and compaction, the number of snow layers is adjusted by combining or subdividing them. This process is based on the work of Jordan (1991).

The key points are:

1. Snow temperature, including phase change, is determined in Chapter 2.6.
2. Snow hydrology is covered in Chapter 2.8.
3. Snow compaction calculations are described in Section 2.8.6.
4. The combination and subdivision of snow layers is then performed, as outlined in this section.
5. The layering adjustments follow the methodology presented by Jordan (1991).

The main purpose of this section is to explain how the snow layers are manipulated after the preceding snow-related calculations have been completed.
