Physical Stream Dynamics and Native Mussel Habitats

Freshwater mussel conservation efforts depend on identifying habitat characteristics that are suitable for mussel reintroduction and restoration. CERC scientists are conducting research to understand how physical habitat dynamics affect the distribution of mussels and suitable habitat in streams and rivers.

One-dimensional hydraulic and environmental DNA transport models for the Wallens Bend reach of the Clinch River, near Kyles Ford, Tennessee

This dataset includes the one-dimensional HEC-RAS model calibration files and simulation input and output files for the Wallens Bend (WB) reach on the Clinch River near Kyles Ford, Tennessee. Simulation results were used as input for environmental DNA transport models.

Hydraulic measurements from select reaches of the Big River, Missouri

This data release contains river bed surface grain size measurements, water-surface elevation measurements, and digital elevation models (DEMs) for select reaches of the Big River, Missouri. These data were collected in support of research assessing the hydraulic conditions of freshwater mussel habitat in the Big River. The individual metadata associated with each data type describe the...

Detection and transport of environmental DNA from two federally endangered mussels

Environmental DNA (eDNA) offers a novel approach to supplement traditional surveys and provide increased spatial and temporal information on species detection, and it can be especially beneficial for detecting at risk or threatened species with minimal impact on the target species. The transport of eDNA in lotic environments is an important component in providing more informed...

Bedform distributions and dynamics in a large, channelized river: Implications for benthic ecological processes

Sand bedforms are fundamental habitat elements for benthic fish in large, sand-bedded rivers and are hypothesized to provide flow refugia, food transport, and ecological disturbance. We explored bedform distributions and dynamics in the Lower Missouri River, Missouri, with the objective of understanding the implications of these features for benthic fish habitat, particularly for the...

Hydraulics of freshwater mussel habitat in select reaches of the Big River, Missouri

The Big River is a tributary to the Meramec River in south-central Missouri. It drains an area that has been historically one of the largest lead producers in the world, and associated mine wastes have contaminated sediments in much of the river corridor. This study investigated hydraulic conditions in four study reaches to evaluate the potential contribution of physical habitat dynamics...
