My research integrates numerical modeling, field survey, and theory to inform sustainable delta management.
Deltaic environments possess an abundance of natural resources that are critical for societal wellbeing. However, delta sustainability is uncertain, due to a multitude of natural and anthropogenic factors including sea-level rise, sediment supply reduction due to damming, land subsidence, and river avulsion. These challenges to delta sustainability are surmountable, but understanding deltaic system complexity is prerequisite to sustainable management.
The following sections describe research projects I have designed and led.
Predicting deltaic avulsion timing and location
Subsurface uncertainty quantification
All research projects:
Vertical sediment concentration distribution is altered in high-concentration flows, and therefore impacts the efficacy of sediment-extraction infrastructure.
Deltaic avulsion causes flooding and channel relocation. Predicting when and where avulsions occur will improve landscape stability for society living on a d...
Over geologic time, sediment flux to coastlines may depend on large-scale drainage capture events.
A limited understanding of subsurface flow patterns inhibits our ability to sustainably manage water resources and mitigate health risks in river-delta envir...
