- •
Effects of TIA and DCIA on urban runoff in small urban catchment are analyzed.
- •
TIA is more effective in affecting total and peak runoff volume.
- •
DCIA is more likely to affect runoff lag time without the contribution of TIA.
- •
Their performances vary significantly according to different storm characteristics.
- •
These findings can be explained by the spatial scale and the rainfall conditions.
