Rapid urbanization has increased the frequency of flood disasters, causing devastating effects globally. This study selected the Jinhua River Basin as the study area and used the ecological embankment strategies of Yanweizhou Park as a typical model to explore the flood control effects of different ecological embankments. The SWAT (Soil & Water Assessment Tool) model was used to simulate flow regulation, peak flow reduction, and peak stage adjustment in the Jinhua River Basin under 129 embankment scenarios with different design forms and area ratios. The study found that as more concrete embankments were replaced by ecological embankments, the flow during the flow hydrography was smoother, with a maximum annual peak flow reduction rate of 63%. Yanweizhou ecological embankment strategies have better peak flow reduction effects than the concrete embankments. The Yanweizhou ecological embankment strategies can successfully resist all floods during the simulation year, and can effectively prevent the hardening and bleaching of the river, and thus have a strong application value.
