Effective flood management strategies in these settings require a careful consideration of the interactions between tributary flows and the main river, as the synchronization of peak flows can intensify flood severity. Using a counterfactual hydrodynamic modeling approach, this study investigates how modifications to magnitudes and timings of tributary inflows, as part of practical flood mitigation interventions, influence flood dynamics and overall flood risk along the Vermilion River in south Louisiana, USA—a representative a case study. Simulations of various tributary desynchronization scenarios showed that, while managing individual tributary flows can lower water levels in the main river, simultaneous manipulation of multiple tributaries can introduce added complexities, since poorly timed tributary interactions could diminish the intended flood mitigation benefits. The analysis also revealed that alterations to tributary hydrographs can modify existing flow exchanges between the river and interconnected large natural storage systems, such as swamps, highlighting the importance of comprehensive flood management strategies that consider different flood dynamics in low-gradient river systems.

In this study, a three-layer physical modeling environment was developed to represent the dynamics of runoff production from the urban drainage system. The three-layer physical modeling environment consists of a rainfall simulator (the 1st layer), a surface drainage network (the 2nd layer) and a subsurface rainwater pipe network (the 3rd layer). The degree of homogeneity of the spatial rainfall distribution produced by the rainfall simulator ranged from 78.6% to 84.0%, which lies within an acceptable range in the rainfall uniformity. The physical catchment model accurately represented the dynamic characteristics of the catchment response in a natural system associated with differing rainfall intensities within a controlled laboratory modeling environment, particularly the magnitude, volume, and shape of the discharge hydrographs. The three-layer physical modeling setup was implemented to identify the effects of stormwater management facilities such as the rooftop detention storage and the permeable road pavement on the urban rainfall-runoff responses. The runoff reduction rates for the peak discharge and the total discharge volume showed a strong linearity with the percentage coverages of the stormwater management facilities. Functional relationships between the variables were established to provide intuitive criteria for the runoff reduction rates for a specific coverage percentage of the rooftop detention storage and the permeable road pavement.

Moreover, bridge blockage from debris accumulation was methodically investigated under multiple return periods. Results indicated that during the two historical floods, the bridges altered the distribution pattern of flash floods from various flood elements, including the backwater effect, flow velocity, and inundation. It is noteworthy that the spillway bridge (M1) notably raised water levels and slowed flows, whereas the influence of other bridges on flood dynamics was more muted. The presence of six bridges resulted in expanded flooded areas, particularly near the upstream bridges, raising risks for Qishi Village. Furthermore, the increasing blockage ratios at bridge B2 during multiple return periods exacerbated the impacts on flood elements, consequently amplifying the disaster of flash floods.
