Overview

This tutorial explains and demonstrates a scalable wetland and peatland modelling approach, implemented by the Dynamical Peatland Model Based on TOPMODEL (DYPTOP) (Stocker, Spahni, and Joos 2014). The demonstration contrasts two regions, the extent around the central Congo Basin peatland complex (Figure 1) (Dargie et al. 2017), and Switzerland (Figure 2) in Chapter 2. Chapter 3 then demonstrates the application of the DYPTOP modelling approach at the global scale.

Figure 1: Region used for demonstration around the Central Congo Basin peatland complex. The maps shows the Compound Topography Index (CTI), which measures the tendency for subsurface water flow convergence and a shallow water table depth (or flooding) based on the TOPMODEL (Beven and Kirkby 1979). CTI data is from Marthews et al. (2015).
