Selection of Design Events in Tidally Affected Detention Pond Systems (RESEARCH NOTE)

In this paper the development of a single set of design parameters of the sizing of the tidally affected detention pond system was analyzed and tested. The approach uses critical duration single storm event of specified return period, together with a single harmonic tide. The design flood level is then the aggregate of the levels obtained using the system model with the four phase lags between the high tide and peak inflow. The inequality resulting between the return period of the storm and the resulting aggregate level is adjusted using a modeling factor. The modeling factor is seen to vary significantly with the level of the offsite sewer and this variation is quantified.
