What does this research mean for the field?

Increasing the implementation area of Low Impact Development (LID) practices beyond 10% of the total impervious area does not significantly improve runoff reduction under frequent rainfall events, and their performance is governed primarily by storage capacity rather than the specific type of practice. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Simulation study reveals a 10% impervious area footprint optimizes runoff control in an urban catchment, indicating storage capacity governs performance over specific practice design.

Key Points

To evaluate the long-term hydrological performance and drainage impact of five low impact development practices across varying implementation area proportions in an urban catchment.
Simulated five low impact development practices—bioretention cells, rain gardens, infiltration trenches, permeable pavements, and vegetative swales—using long-term continuous rainfall modeling.
Evaluated hydrological response across implementation footprints covering 10%, 15%, 20%, and 25% of the total impervious area in a university drainage catchment in Brazil.
Increasing low impact development treated area from 10% up to 25% of total impervious surface produced no significant additional reductions in flow rate, peak flow rate, or flooding volume during frequent low-intensity rainfall events.
A minimum treated footprint of 10% of the impervious area proved hydrologically sufficient for maximizing infiltration depth under the evaluated conditions.
Runoff mitigation performance was governed primarily by storage capacity and exfiltration opportunity time rather than the specific structural design of the practice.
