Estimation of Geyser Potential at Network Scale using SWMM 1: Maseeh Department of Civil, Architectural and Environmental Engineering, The University of Texas at Austin, United States of America; 2: Department of Civil and Environmental Engineering, The University of Wisconsin-Madison, United States of America; 3: Department of Civil and Environmental Engineering, Auburn University, United States of America Stormwater geysers erupting from manholes create hazards to urban infrastructure, public health, and safety during extreme storm events. Such geysers are the consequence of adverse multiphase flow interactions that conventional models, such as SWMM, do not capture. Most prior geyser studies have focused on local multiphase interactions using experiments or multi-dimensional computational fluid mechanics, which are difficult to scale up to large networks. Herein, a new method is developed that bridges the gap between detailed geyser representations and practical modelling constraints. This approach quantifies air entrapment in network segments based on the analysis of conduit geometry and inflow parameters. Air entrapment is a necessary precursor for geysers, so quantifying the entrapment potential provides a means of estimating geyser potential without requiring computation of the geyser physics itself. The method is applicable for a wide range of network configurations and provides a scalable tool for identifying geyser-prone areas, thus advancing large-scale urban stormwater management. | |
