Advancing Environmental Flows Science: Hindcasting and Forecasting Flow–Ecology Relationships

open access: yesFisheries, Volume 49, Issue 8, Page 353-368, August 2024.
To advance current environmental flow standards in Texas, we developed field, laboratory, and analytical methods to model recruitment dynamics of indicator species selected to cover a range of population responses to flow variation. Preliminary investigations were conducted in three central Texas river basins to evaluate the feasibility of these ...
