Building a river model in InfoWorks ICM
This tutorial has been designed to help you understand the various steps involved in building a river model in InfoWorks ICM.
Before making a start on this tutorial, please ensure you have read the Tutorials Welcome page as it contains important information about installing the provided example data.
When building rivers, the basic assumption in InfoWorks ICM is that you have reliable survey data available in an external source. This would typically be river cross section data (X,Y,Z points), bridge cross section data (X,Y,Z points) and a centre line for the length of river to be modelled.
It is also advantageous to have good LiDAR data for the surrounding area available to capture items such as bank lines, pond and ditches. Once you have built the river reach you will need to have flow data to input and simulate.
This short tutorial uses all of the data outlined above. It concentrates on the specific River modelling tasks, and assumes the user already has a grasp of basic InfoWorks ICM functionality.
This tutorial uses a simple example to guide you through the main aspects of building a river model in InfoWorks ICM, showing you how to import ground model data, cross section survey data and river centre line data, create a river reach object, define banks, build banks for selected lines, add a storage area, define river boundaries and run simulations. A number of GeoPlan facilities such as themes are described and illustrated.
The tutorial has been split into ordered sections. The sections included in this tutorial are:
step 1 - Importing LiDAR/ground model data
step 2 - Building a river reach from cross sections
step 4 - Adding bank spill sections
step 5 - Running simulations on the river model
step 6 - Viewing simulation results
It is important to note that these sections MUST be completed in order. Every time a river reach is built in InfoWorks ICM this order should be respected.
