A Micro-Catchment Block-to-Inlet Framework for Diagnosing Nuisance Flood Failure Mechanisms under Dual Storm Typologies
Author(s): Tefera Shibeshi* and Temesgen Mekuriaw Manderso
Urban neighborhoods, such as Kensington in Philadelphia, frequently encounter nuisance flooding, which is characterized by shallow surface ponding around street inlets during moderate rainfall events. These recurrent low-depth floods disrupt mobility, damage infrastructure, and disproportionately impact vulnerable communities, often occurring below conventional stormwater design thresholds. This study introduces an uncalibrated, diagnostic micro-catchment block-to-inlet modeling framework aimed at identifying localized hydraulic failure mechanisms, rather than replicating observed flood depths. High-resolution elevation data and parcel-scale impervious surface mapping were employed to delineate inlet-based micro-catchments, each approximately 5 ha in size. These micro-catchments were integrated into a comprehensive EPA SWMM (v5.2) hydraulic-hydrologic model of a 3.5 km2 urban drainage.. Read More»
