Citation:
Yang, J. Flooding Risk and Potential Impacts on Water Infrastructure at Lawrence, Massachusetts. Presented at R1 project briefing, Boston, MA, June 21, 2018.
Impact/Purpose:
Present research results on flooding risk to project members and ex-EPA collaborators. Spicket River: High flash flood risk due to the increasing downpours and channel blockage, with Impact to pipe network and SSS/CSS structures. Merrimack River: Berm designed against 100 yr flood or 1% annual flood. The BF elevation appears equal to 1.6% annual flood. Inundation to water treatment plant is at 2.4% annually or 2.4 day-events per 100 years. Inundation duration is 2.4 days per event. The risk of losing service is high.
