As water professionals, we are continuously being challenged to develop better outcomes for our communities and the environment, and hydraulic modeling is central to understanding those outcomes. Whether the need is running ‘what if’ scenarios’ to explore a series of unknowns, determining flow conditions and sizing solutions to get the right answers or forensically looking into failure modes and resolving the problems, hydraulic models play an important role managing our collection systems. In this webcast three case studies will be presented that demonstrate how hydraulic models are being applied to understand risk, improve the certainty of outcomes and add value in relation to Climate Change, Continuous Model Calibration and Urban Flood Mitigation.
- Bob Swarner (King County), who will present on Assessing Climate Change's Impact on the Size of CSO Facilities in King County. This presentation will describe how King County WTD simulated the rainfall generated by two Global Climate Models, using calibrated sewer models, to estimate how climate change might impact the size of combined sewer overflow control facilities necessary to meet regulatory requirements. The results showed control volumes at 29 CSOs could increase by up to 87 million gallons, 58%, by the end of this century.
- Hazem Gheith (Arcadis), who will present his work on Continuous Hydraulic Model Calibration and specifically how adopting a source-based continuous model calibration approach using long-term flow monitoring data is being applied in Columbus, OH. The presentation will detail how Columbus calibrated their sewer system models in 2009 and compare with the latest calibration comparisons for 2020. These comparisons will show how in the interim years, calibration techniques, needs and benefits have evolved to improve modeling standards increase certainty for solutions.
- Erik Haniman, (Philadelphia Water Department), Elise Ibendhal and Anjulie Cheema (both Jacobs) will present on their 2-Dimensional Hydraulic Modeling experience in Germantown, a neighborhood in northwest Philadelphia. Germantown is a combined sewer network, that experiences significant surface and basement flooding. The presentation will describe how the team were able to understand and mitigate the extensive urban flooding using a unique phased approach, including the use of integrated 1D and 2D hydraulic modeling, performing detailed calculations of flood damages, and optimization of future capital improvements.
