Current Projects

climatic controls on Mississippi River floods

This project uses sedimentary archives recovered from the floodplains of the Mississippi River and its major tributaries together with climate reanalysis data sets and Earth system model output to understand the climatic controls on Mississippi River flood hazard and fluvial export to the Gulf of Mexico. Collaborators: Liviu Giosan & Jeff Donnelly (WHOI), Zhixiong Shen (CCU), Matt Therrell (Alabama), Jon Remo (SIU), Sylvia Dee (Rice), Mississippi River Museum and Aquarium. Funding from NSF-P2C2 (award no. 1804107) and the Ocean & Climate Change Institute.

Contextualizing Hurricane Harvey

In August 2017, Hurricane Harvey produced catastrophic flooding across southeast Texas that caused over $100 billion in damages. Rainfall totals and river flows associated with Hurricane Harvey shattered records across southeast Texas, but these records span only the last ~100 years. This project will improve flood hazard assessments for precipitation and discharge extremes in southeast Texas by coupling geological evidence of pre-instrumental floods to a hydrologic model. Collaborators: Ed Beighley (Northeastern), Pete Van Hengstum (Texas A&M), Paul Hudson (Leiden), Center for Texas Beaches and Shores. Funding from NSF-HS (award no. 1833200).

improving coastal flood predictability in new england

This project integrates high-fidelity computer models with observations of water levels and sediment deposition from recent coastal storms to develop a unified and standardized flood hazard assessment system. Collaborators: Jim Chen & Raymond Fu (Northeastern). Funding from the Global Resilience Institute.

contaminant mobility across the land-sea interface

Industrial contaminants are detrimental to human and ecosystem health, and can continue to be mobilized by geomorphic and biochemical processes for decades. This project examines the stability of industrial contaminants in floodplains and the coastal ocean at several locations across New England and the Atlantic Coastal Plain. Collaborators: Loretta Fernandez & Phil Larese-Casanova (Northeastern), Zhixiong Shen & Till Hanebuth (Coastal Carolina U.). Funding from NSF-GLD & NSF-GG (award no. 1902126).
