Understanding integrated models
Identify an integrated model and name the different model types.
In the past, hydraulic models would focus on a single system. With Integrated modelling, you represent multiple systems in a single model network.
There are four basic types of integrated models:
- 1D linked model
- 2D runoff model
- 1D-2D linked model
- Full integrated catchment model
A 1D-2D linked model improves on a 1D model, in that it more accurately represents the route and the impact of flooding.
The full integrated catchment model type, also known as a “whole catchment model” contains all systems within a single model.
When the detail in a model is increased, so is the resource required. This includes the time it takes you to build and simulate the model, and its entire lifecycle, starting with data collection, to storage, and finally, archiving.
When creating a project, choose the simplest model type that provides you with the level of confidence that you require for your outputs.
