Simulated storm event flow design and modelling for stormwater treatment studies

Abstract

Urban stormwater is a major non-point source of aquatic pollution. It is necessary to design and implement pilot experiments to investigate the effect of specific forcing functions under controlled conditions. In this work, a simple storm event inflow is designed to simulate a variable duration storm event using only a pump and mixer. The results indicate that two-phase straight inflow changed to right-skew convex curve after cylinder transformation. The method can be used to rapidly design simulated variable duration storm event flows for pilot studies for researchers, hydrologists and engineers.

Keywords:

• storm event design
