PAGE IN PROGRESS - MORE COMING SOON!

Comparisons of how the different modelling tools included in this wiki represent some particular catchment features that one may want to explicitly include in a model are summarised below and covered in more detail in linked content pages. These features, such as tree plantations or small farm dams, may exert a large influence on the hydrology of the catchment you are trying to model. Changes in these features may also be the express reason why you are modelling the catchment, i.e., to estimate the potential impacts of clearing invasive alien plants, restoring wetlands, or expanding irrigation in a particular area.

The reason for modelling a catchment should be one of the main considerations involved in selecting a modelling tool for a particular application. It likely won't be the only consideration, as practical issues are also important (see modelling process overview here), but it is a key one. It is worth being familiar with the various capabilities, limitations, and differences in how these particular elements are represented across models when they are main features of your study catchment.

Invasive alien plants (IAPs) & afforestation

Riparian zones

Riparian zones

Wetlands

The definition of wetland representation and an outline of the fundamental wetland descriptions which differentiate wetlands in modelling tools is presented in the wetlands page.

Irrigation

This section provides a summary of how the various tools represent irrigation from different sources. A detailed description of irrigation representation is found here.

Irrigation from groundwater

● Pitman tools & ACRU: Do not include irrigation from groundwater. ACRU does not include any groundwater withdrawal. Work-arounds in the Pitman tools do not allow for dynamic curtailment of irrigation when groundwater supplies are low.

Irrigation from reservoirs

● MIKE-SHE appears not to include irrigation from storage reservoirs, only runoff river and groundwater

Irrigation from multiple sources

● Pitman tools, ACRU, & SWAT only allow an irrigated area to be irrigated from one source, while MIKE-SHE allows multiple sources to be drawn upon in sequence to meet demands.

Small farm dams
