An Alternative Method for Estimating the Peak Flow for a Regional Catchment Considering the Uncertainty via Continuous Simulation

Iain Brown,
Kevin McDougall,
Sreeni Chadalavada
et al.

Abstract: Estimating peak flow for a catchment is commonly undertaken using the design event method; however, this method does not allow for the understanding of uncertainty in the result. This research first presents a simplified method of fragments approach to rainfall disaggregation that ignores the need to consider seasonality, offering a greater diversity in storm patterns within the resulting sub-daily rainfall. By simulating 20 iterations of the disaggregated sub-daily rainfall within a calibrated continuous simu… Show more

“…Hydrologists have conducted extensive research on the selection [1], calibration [2][3][4][5], and uncertainty assessment [6][7][8][9][10][11] of hydrological models to obtain optimal information from these models. In the calibration or uncertainty assessment of hydrological models, observational data play a pivotal role, with the critical elements being the length of the data and the climatic conditions (e.g., dry years, normal years, and wet years) to which the data belong [12].…”
