Analysis of The Historic Brandywine Creek Flood of 2021
The Brandywine Creek, which flows through a densely populated region of eastern Pennsylvania, flooded repeatedly in 2021, culminating in a record-setting flood resulting from the remnants of Hurricane Ida. The Brandywine Creek flood is one of many examples of unprecedented flooding that occurred in the Mid-Atlantic region in 2021, which suggests that any lessons learned have regional applicability. Drawing from GIS and modeling analysis, this presentation will examine the hydrologic processes which contributed to this destructive natural disaster and will discuss the floodplain management and hydrologic modeling implications.
Andrew Sarcinello has 7 years experience working as a water resources engineer in Virginia. Most of his recent work consists of hydrologic and hydraulic modeling of stormwater systems and floodplains to assist municipalities with prioritizing flood mitigation projects or navigating the FEMA CLOMR/LOMR application process. This year will be his third time presenting at VLWA. He also works on dam break inundation zone studies, inspections, and emergency action plans for state-regulated dams as well as stormwater BMP design projects.
