Viewed as a success story, the model is used as a best practice example for future development throughout Sweden. We utilize our in-depth hydrologic and hydraulic engineering knowledge and apply our extensive experience to assist municipalities in safeguarding their communities and preventing loss of life and property.

WSP has worked on the implementation of large-scale, wide-area water system and river management schemes Our experience includes hydrologic and hydraulic solutions to address the engineering challenges associated with transportation and environmental restoration projects. Specialized technical services include waterway modelling, highway drainage and hydraulic design; bridge hydraulics and scour analysis; scour protection; and floodplain analysis and flood control design.

We have also contributed to stream restoration and protection using fluvial geomorphology-based stream restoration and bioengineering techniques. Throughout the regions, WSP employs various modelling software packages for modelling 1D and 2D flows in rivers and over flood plains. Integrated flood risk assessments are also made where surface water processes and flow in sewage networks are modelled simultaneously. WSP works with ports and with coastal engineering breakwaters, quays, locks, etc.

As coastal modelling is also a growing field, we use software for modelling of 2D and 3D flows in estuaries and coastal areas. WSP is helping CSL Behring deliver a new base fractionation manufacturing facility at its Broadmeadows site, which includes the development of three distinct facilities, to fully integrate the Privigen and AlbuRx facilities into its global supply chain and allow end-to-end manufacturing.

The firm wanted to align the building with its core purpose and create better health outcomes for its members, employees and the community. The Carillon generating station, built in , produces some MW of energy.

The 1D models are limited, however, to gross system performance and are limited in their ability to predict the effects of flow distribution, particulate distribution, and localized hydrodynamics on system performance.

Two-dimensional 2D models begin to integrate the physics of the flow into the prediction of the performance of the system as well as individual system components. In general, these models allow for the simulation of lateral variations of flow within the system and system components while calculating average values for dependent variables across the depth.

This becomes particularly important when trying to predict flow splits between system components as well as lateral particulate distribution within inflow boxes and discharge conduits. Water surface profiles in open channels and conduits are predictable with 2D models as long as surface roughness characteristics are known. Using 2D models, more of the hydraulics of the system components can be included in the simulation process, leading to a more accurate representation of overall system performance. With the added dimension, 2D model solution run times are generally longer than those associated with 1D models.

Further, 2D models cannot capture variations of flow and other dependent variables in the vertical direction, and therefore are limited in their ability to more accurately model the hydraulic performance of many system treatment components. Modelers are beginning to couple the 1D and 2D modeling approaches to offer better system predictability than a 1D model alone can offer.

Figure 2. Three-dimensional 3D computational fluid dynamic CFD models are the most sophisticated and predictive numeric hydraulic models available to aid in the design process and incorporate the full three-dimensionality of the flow. Modeling of flow turbulence and energy dissipation is included in these models and facilitates proper prediction of complex hydraulic, chemical, and thermal mixing processes. CFD models are typically used to evaluate the performance of individual process components settling basins, clarifiers, filters, etc.

CFD models are generally very computationally intensive and, depending on the complexity of the process being modeled, can require from a few hours to a few days or weeks to complete simulations. With all of their sophistication, CFD models do have their limitations.

In particular, unsteady vortical flows with the potential for air entrainment such as those associated with pump intake hydraulics and flow-through process systems, where the fate of floatables is of concern, pose challenges for CFD models. Further, simulation of flow events that take place over long time periods i. While sophisticated in its ability to simulate complex flows, CFD modeling requires experienced engineers to set up, run, and interpret the simulation results.

Numeric models will always yield simulation results; it takes an experienced modeler to ascertain whether or not the results are physically plausible and accurate for the system under investigation. Figure 3. Laboratory-scaled physical modeling has been conducted on civil works systems for over years and the scaling laws associated with implementing this modeling approach are well understood. Physical modeling is generally implemented during the design process to study critical system components that cannot be accurately simulated using CFD. One area in particular where performance cannot be accurately simulated is with pump intake structures.

CFD is not capable of accurately predicting the intermittency and strength of vortical flow structures that can develop at intakes and cause degraded performance of the pumps. Physical modeling is also often employed to study complex flow splitting structures and the fate of floatables. In general, of all of the available modeling options, physical modeling offers the most accurate representation of prototype performance.
