Abstract
Stormwater management in urban areas is complex, in part because of difficulties related to modeling water flowing in closed conduits, as well as to controlling odor, noise, and pipe corrosion. This thesis summarizes the main findings of a study on how changes in inflow discharge and the geometry of a stormwater main may affect water flow, and how changes in water depth impact air volume and pressure around an air shaft. The study is conducted using CHAN, a one-dimensional model that simulates both flow hydraulics in mains and associated changes in air volume and pressure around air shafts. Main difference between CHAN and numerical models that are typically used in the profession is that CHAN estimates changes in air volume and pressure driven by changes in water depth, providing a more comprehensive understanding of system behavior that can be of aid in odor control.
