Flow regimes and environmental flows
How altered flows affect fish and macroinvertebrates, and how much water rivers need to keep functioning.
How rivers flow, dry and recover, and what that means for the life in them.
We are a hydroecology lab at Texas State University. We combine watershed and ecological models with field and lab observations to understand how changing flow regimes shape freshwater biodiversity and ecosystem function.
What we work on
Connected questions about how water moves through river networks, the life it supports and the work rivers do.
Intermittent rivers
When and where streams stop flowing, and how river networks and their communities respond to drying and rewetting.
Biodiversity and stream function
How freshwater biodiversity and stream ecosystem functions respond as flow regimes change.
Watersheds under change
SWAT+ modelling and long-term records to assess climate and land-use effects on floods, droughts and low flows.
