Hydrologic and geomorphic flow thresholds in the Lower Brazos River, Texas, USA

River science and management often require a design or reference discharge. The common (and sometimes unavoidable) use of such discharges may, however, obscure the fact that the magnitude and frequency of critical flows can differ due to various hydrological, geomorphological, and ecological criteria. Threshold stages and discharges were identified for six lower Brazos River, Texas gaging stati...

Not all breaks are equal: Variable hydrologic and geomorphic responses to intentional levee breaches along the lower Cosumnes River, California

River Res Applic. 2017;1–13. Abstract The transport of water and sediment from rivers to adjacent floodplains helps generate complex floodplain, wetland, and riparian ecosystems. However, riverside levees restrict lateral connectivity of water and sediment during flood pulses, making the re‐introduction of floodplain hydrogeomorphic processes through intentional levee breaching and removal an e...

Response of Brazos River Oxbow Fish Assemblages to Patterns of Hydrologic Connectivity and Environmental Variability

—Three oxbow lakes with different connection frequencies and an adjacent reach of the middle Brazos River, Texas, were surveyed quarterly from summer 1993 to summer 1996 to examine the effects of hydrology and physicochemical attributes on fish assemblage structure. During flood events, oxbows usually were colonized by about 20 fish species from the river channel, and several fluvial specialist...

Microaccretionary and Accretionary Carbonate Spherules of the Chicxulub Impact Event from Brazos River, Texas, and Bass River, New Jersey

Accretionary carbonate spherules of small size are a common component of distal Chicxulub impact ejecta deposits and are documented at Brazos River, Texas, and Bass River, New Jersey, located about 1000 km and 2500 km respectively from the crater. This spherule type is also present in northeast Mexico and is related to accretionary carbonate lapilli present in proximal Chicxulub ejecta deposits...
