摘要: Urbanization impacts the stormwater regime through increased runoff volumes and velocities. Detention ponds low impact development (LID) strategies may be implemented to control runoff. Typically, mitigation are designed maintain postdevelopment peak flows at predevelopment levels for a set of design storms. Peak flow does not capture extent changes hydrologic regime, footprint residence (HFR) was developed calculate area duration inundated land during storm. This study couples cellular automata cover change model with hydraulic framework generate spatial projections future on fringe rapidly urbanizing metropolitan area. The is characterized existing projected patterns under detention pond LID-based control, using HFR values. Results demonstrate that less intense frequent rainfall events, LID solutions better respect HFR; larger storms, perform flow.
