Implementing rain garden (RG) designs is widespread worldwide to reduce peak flow rates, promote stormwater infiltration, and treat pollutants. However, inadequate RG design degrades its hydrological behaviour, requiring the development validation of an appropriate model for analysis structures. This study aimed improve a infiltration based on Darcy’s law by taking into account height water column (HWC) at surface filtration coefficients soil materials. The was tested simulating characteristics single event critical intensity (36 mm/h). Using validated model, curves were obtained that predict performance as function main parameters structure: height, ratio catchment area structure area, layer thickness, coefficient. efficiency evaluated in terms time complete saturation, filling with water, determining change HWC caused changes parameters. coefficient thickness upper intermediate layers are affect depth saturation surface. not very sensitive related lower gravel layer. If top layer’s increases 10 cm, it takes longer fill reaches 0.341 m. garden’s improves when 7.0 cm/h. Complete rainwater do occur within 7200 s, 0.342 m this effectiveness decreases if exceeds 15 cm/h 25 cm/h, respectively, or values below 15. modelling results confirm considering models essential designing structures minimise risk overflow during intense rainfall events.
