Water resource engineering is the process of managing the collection of water to control its flow and avoid flooding. This process is controlled by pipe designs and networks that support both dry and wet weather flow conditions.  In a society concerned with the effects of climate change, the ability to prevent flooding is set to become an increasingly important requirement as extreme weather conditions, such as intense rain storms, are expected to occur more frequently. Traditionally, flooding regions of a model are explored iteratively by the engineer, who would manually change the model until a solution that meets the requirements of the flooding constraints is found.

Water resource engineeringWater Resource Engineering from the Numerical Perspective

The process of calibration and verification of the models can take up a significant amount of an engineer’s time due to the long process needed to ensure that the quality of the models, as described in the quality modelling guidelines by WaPUG (2006, P. 26-31), is respected. A simple network covering a small area could possibly include thousands of pipe networks and subcatchments, not to mention the pumps and storage tanks that also need to be taken into consideration.

This is where numerical simulation comes in. Numerical simulation substantially reduces the man-hours spent in the verification process, saving time and money through:

  • automated calibration
  • automated design optimization
  • highlighted diagnostic information

All of this enables engineers to spend more of their time on understanding the solutions to existing problems.

In our studies all simulations are carried out using the industry-standard software InfoWorks CS, making them compliant with industry practices even when solutions have been optimized using modeFRONTIER. ModeFRONTIER was able to produce an advanced Pareto Frontier beyond the manually engineered solution, creating a theme of design solutions to be explored by the engineer.

The Added Value from Numerical Simulation

The ability to automate techniques applied with smart optioneering enables a range of alternative designs; the designs are also available to be explored upfront at the design stage to give clear direction to the project. In addition, cost models could also be incorporated to cover all possible design requirements, which allows for any design or theme of designs to be compared on the basis of cost and performance.

In a nutshell, numerical simulation:

  • reduces the time spent verifying models
  • allows for more efficient capital solutions to be developed through the “optioneering” process
  • increases software utilisation, maximising your resources to work for you outside of normal office hours

Case Study

  • 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.
