In the past, hydraulic models would focus on a single system.
00:10
For example, a sewer network model was separate from a river model.
00:15
Each model was simulated in its own network.
00:18
Different software packages may even have been used for the different models.
00:23
With Integrated modelling, you represent multiple systems in a single model network.
00:29
There are four basic types of integrated models:
00:32
the 1D linked model,
00:34
the 2D runoff model,
00:36
the 1D-2D linked model,
00:38
and the full integrated catchment model.
00:41
The 1D linked model is a single model network containing the piped and riverine systems.
00:47
In a 1D linked model, you connect points of interaction between systems to allow the exchange of flows.
00:54
For example, points where the outfall from a sewer system connect to points in the river model.
00:59
The next type is a 2D runoff model.
01:01
Rainfall or flow is applied directly to a 2D mesh.
01:05
The flow is routed over the mesh surface, which represents the underlying topology.
01:10
The third type is a 1D-2D linked model.
01:14
These are often flood routing models.
01:16
This model is different from a 2D runoff model in that the purpose of the 2D mesh is to only route the overland flows due to flooding.
01:24
A 1D-2D linked model improves on a 1D model, in that it more accurately represents the route and the impact of flooding.
01:33
Finally, the full integrated catchment model type, also known as a “whole catchment model” contains all systems within a single model.
01:41
Full integrated catchment models have now become commonplace.
01:45
However, as the detail in a model is increased, so is the resource required.
01:50
This includes not only the time it takes you to build and simulate the model, but also through its entire lifecycle,
01:56
starting with data collection, to storage, and finally, archiving.
02:01
When creating a project, best practice is to choose the simplest model type
02:06
that provides you with the level of confidence that you require for your outputs.
