Nuisance flooding

Moftakhari, H. R., AghaKouchak, A., Sanders, B. F., Allaire, M., & Matthew, R. A. ( 2018). What is nuisance flooding? Defining and monitoring an emerging challenge. Water Resources Research, 54, 4218– 4227.

Hurricane Sandy (2012) affected trees for more two years

 London plane trees, once

thought to be salt tolerant, fared poorly on Long Island and in NYC after Hurricane

  • Sandy. Photo Courtesy

 In the summer of 2014, Long

Beach took down more than 1400 dead trees.

Understand the process by land

  • cean interaction modeling

 What types of topography are vulnerable to storm surges?  How to mitigate groundwater salinization?
