Calibrating Area Network Drainage Models in Infoworks CS

The costly and labor intensive process to accurately calibrate slow runoff parameters is well recognized in the water industry. It can often take the engineer as long as a week or more to calibrate just one flow monitor. This is why we have built an interface that bridges InfoWorks and ModeFRONTIER. It is essentially a spreadsheet that links modeFRONTIER with InfoWorks CS allowing  engineers to automate the calibration and optimization process, leaving modellers more time to focus on other aspects of the job such as the end verification process.

The Capabilities of the ModeFrontier Interface

The ModeFRONTIER interface has the ability to automatically adjust the InfoWorks model until the ‘best’ match of the model is validated. It has the improved ability to include any parameter set by the modeller.

Through the interface engineers can select parameters of their model for automatic adjustment within the run sequence. Thereafter, the engineer can leave the interface to work unattended. Modellers can even set up the run sequence to work outside of normal work hours or even throughout the weekend.

The capability of “smart optioneering” automates the exploration of the design space, identifying any themes and a series of improved solutions with consideration of the constraints and objectives of the project in order to find the optimum solution.

Simulations carried out by the modeFRONTIER Interface significantly reduces the time to manually calibrate flow monitors, leading to potential savings in the direction of 10% where the software can effectively pay for itself.

From the words of Mr. David Searby, Technology Manager, Wessex Water:

“modeFRONTIER has been used successfully on two small trial catchments to date, to assist in both standard model calibration and the tuning of slow runoff parameters. The results have been encouraging from the standpoint of quality of verification fits and speed of analysis. The method is largely automatic, and so frees the engineer to tackle other aspects of the verification. The process is now being applied to larger and more challenging verification projects”
