Ecological Structure and Function, Large-River Floodplains
This project seeks to develop tools and datasets that provide insights to the common ground between flood-risk reduction and ecosystem services on large-river floodplains of the Central United States. Floodplains of large rivers are valued for their agricultural productivity and development potential, but recent floods have demonstrated the high costs and lack of resiliency when floodplains are...
Pallid Sturgeon Habitat Dynamics
CERC scientists apply advanced measurement and modeling approaches to quantifying habitats in large rivers. Our research has been applied to improving the understanding of the reproductive ecology of the endangered pallid sturgeon ( Scaphirhynchus albus) in the Missouri River.
Science to Inform Management of Floodplain Conservation Lands in a Changing World
Recent extreme floods on the Mississippi and Missouri Rivers have motivated decision-makers and resource managers to expaned floodplain conservation lands. Within Missouri, there are more than 85,000 acres of public conservation lands in large-river floodplains. Floodplain lands are highly dynamic and challenging to manage, particularly climatic conditions change. These lands have the...
SERAP: The Effects of Climate Change on Aquatic Species and Habitat in the Southeast
USGS researchers assessed how climate change can affect land cover and flow in river systems, examining a variety of resolutions for detecting and projecting the conditions of aquatic habitats and species.
Pallid Sturgeon Spawning Habitat in the Lower Missouri River Pallid Sturgeon Spawning Habitat in the Lower Missouri River
Lack of reproduction has been hypothesized to be a factor in the decline of the pallid sturgeon (Scaphirhynchus albus) through much of its range. Spawning habitat and behavior have only recently been documented on the Lower Missouri River, which comprises over 1,300 river kilometers of undammed river. This data consists of habitat measurements for ten pallid sturgeon spawning events from...
Segment-scale classification, large rivers of the Upper Midwest United States Segment-scale classification, large rivers of the Upper Midwest United States
This dataset is part of a multi-scale assessment and classification for segments of 15 rivers of the Upper Midwest United States that meet various criteria for largeness. All rivers are tributary to the Mississippi River system. The 11,600 kilometers (km) that qualified as large were parsed into 10-kilometer-long segments and classified by major alterations (free-flowing, navigation...
Missouri River Bend Classification Missouri River Bend Classification
Management actions intended to increase growth and survival of pallid sturgeon (Scaphirhynchus albus) age-0 larvae on the Lower Missouri River require a comprehensive understanding of the geomorphic habitat template of the river. The datasets described here are intended to support decisions relating to where channel-reconfiguration projects should be located to optimize effectiveness of

Evaluations of Lagrangian egg drift models: From a laboratory flume to large channelized rivers Evaluations of Lagrangian egg drift models: From a laboratory flume to large channelized rivers
To help better interpret computational models in predicting drift of carp eggs in rivers, we present a series of model assessments for the longitudinal egg dispersion. Two three-dimensional Lagrangian particle tracking models, SDrift and FluEgg, are evaluated in a series of channels with increasing complexity. The model evaluation demonstrates that both models are able to accommodate...

Sixty years of channel adjustments to dams in the two segments of the Missouri National Recreational River, South Dakota and Nebraska Sixty years of channel adjustments to dams in the two segments of the Missouri National Recreational River, South Dakota and Nebraska
The Missouri National Recreational River (MNRR) consists of two Missouri River segments managed by the National Park Service on the border of South Dakota and Nebraska. Both river segments are unchannelized and maintain much of their pre-dam channel form, but upstream dams have caused reductions in peak flow magnitudes and sediment supply. The 39-mile segment is located between Fort...

Growth and survival rates of dispersing free embryos and settled larvae of pallid sturgeon (Scaphirhynchus albus) in the Missouri River, Montana and North Dakota Growth and survival rates of dispersing free embryos and settled larvae of pallid sturgeon (Scaphirhynchus albus) in the Missouri River, Montana and North Dakota
We released nearly 1.0 million 1-day post-hatch (dph) and 5-dph pallid sturgeon (Scaphirhynchus albus) free embryos in the Missouri River on 1 July 2019 and sequentially captured survivors at multiple sites through a 240-km river reach to quantify daily growth and survival rates during the early life stages. Genetic analysis was used to assign captured fish to released family lots and...

Geomorphic controls on floodplain connectivity, ecosystem services, and sensitivity to climate change: An example from the lower Missouri River Geomorphic controls on floodplain connectivity, ecosystem services, and sensitivity to climate change: An example from the lower Missouri River
Floodplains of large rivers are exploited for agricultural production, industrial and municipal development, and transportation infrastructure. Recently, increased frequency of costly floods has prompted consideration of whether offsetting benefits might accrue from management of floodplains for ecosystem services. We employed a simple inundation model for 800 km of the Lower Missouri...

A three-dimensional Lagrangian particle tracking model for predicting transport of eggs of rheophilic-spawning carps in turbulent rivers A three-dimensional Lagrangian particle tracking model for predicting transport of eggs of rheophilic-spawning carps in turbulent rivers
Grass carp, bighead carp, and silver carp spawn in flowing water. Their eggs, and then larvae, develop while drifting. Hydraulic conditions and water temperature control spawning locations, egg survival, and the downstream distance traveled before the hatched larvae can swim for low velocity nursery habitats. Existing egg drift models simulate the fluvial transport of carp eggs but have

Identifying monitoring information needs that support the management of fish in large rivers Identifying monitoring information needs that support the management of fish in large rivers
Management actions intended to benefit fish in large rivers can directly or indirectly affect multiple ecosystem components. Without consideration of the effects of management on non-target ecosystem components, unintended consequences may limit management efficacy. Monitoring can help clarify the effects of management actions, including on non-target ecosystem components, but only if...
