Wetland hydrological models – Wetland catchment/subcatchment model

Select from the tabs below

• Overview
• Wetland site scale
• Wetland contributing catchment model
• Wetland catchment/subcatchment model

Modelling multiple wetlands within a catchment or subcatchment adds complexity, data requirements, and processing power. Incorporating detailed wetland models as a dedicated ‘module’ or ‘plug-in’ with a broader catchment model may be difficult, depending on the size of the catchment, the complexity of the models, the model framework and configuration, data requirements, and the time steps used in the models[2].

A catchment or subcatchment model can incorporate individual site scale wetlands as part of a node and link network often used to describe a catchment. These incorporate the same forcing factors, constituents and processes as the catchment model, but may be less detailed as noted above.
