The General Lake Model (GLM) is a one dimensional
open-source code designed to simulate the hydrodynamics
of lakes, reservoirs, and wetlands. It includes sub-models that simulate surface heat exchange and ice cover dynamics, vertical mixing, and inflow–outflow dynamics.

Spin-up
Was A Spin-Up Performed?: Yes
Spin-Up Design: Three years of data were appended to the beginning of the meteorological forcing data and used to spin up the model.
Extreme Events & Disturbances
Key Challenges: Extreme events tend to occur on a temporal scale shorter than one day so using forcing data at a daily timestep makes it difficult to capture such events.
Calibration
Was The Model Calibrated?: True
Which Years Were Used For Calibration?: 1979-2016
Which Dataset Was Used For Calibration?: EWEMBI
How Many Catchments Were Callibrated?: 60 lakes
