Methods
The model
We use an eco-physiological process-based growth model for submerged
macrophytes named Macrophytes Growth Model (MGM). It is based (Figure
1a) on the model Charisma 2.0 (van Nes et al., 2003), which in turn
builds on the model Megaplant (Scheffer et al., 1993). The MGM is a
re-implemented and simplified version of Charisma 2.0 written in the
programming language julia (Bezanson et al., 2017) for faster
performance.
