Mississippi/Atchafalaya River Basins - SPARROW

SPARROW, a modeling tool for the regional interpretation of water-quality monitoring data. The model relates in-stream water-quality measurements to spatially referenced characteristics of watersheds, including contaminant sources and factors influencing terrestrial and aquatic transport. SPARROW empirically estimates the origin and fate of contaminants in river networks and quantifies...

LAWSC provides easy flood tracking on the web – 25 May 2007

Flooding is a concern for everyone in Louisiana. Floods demand immediate and decisive action by governmental entities, businesses, and individual citizens, all of whom have to make critical decisions that directly impact the extent, duration, and mitigation of losses resulting from flooding. How high will the water get? How long will the flood last? What areas will be affected? What roads will...

Quantitative Analysis Using Structural Equation Modeling

USGS scientists have been involved for a number of years in the development and use of Structural Equation Modeling (SEM). This methodology represents an approach to statistical modeling that focuses on the study of complex cause-effect hypotheses about the mechanisms operating in systems. SEM is increasingly used in ecological and environmental studies and this site seeks to provide...

Streamflow Alteration Assessments to Support Bay and Estuary Restoration in Gulf States

Human alteration of waterways has impacted the minimum and maximum streamflows in more than 86% of monitored streams nationally and may be the primary cause for ecological impairment in river and stream ecosystems. Restoration of freshwater inflows can positively affect shellfish, fisheries, habitat, and water quality in streams, rivers, and estuaries. Increasingly, state and local decision-...

Bats in Forests Managed for Wildlife

The Challenge: Within the Mississippi Alluvial Valley (MAV), forest managers may prescribe variable retention silvicultural treatments within bottomland hardwood forests on public lands to improve forest conditions (i.e., structural heterogeneity, species composition, and senescence) for priority wildlife species. This is referred to as wildlife-forestry silviculture. However, concerns have...

Structure maps of the Carrizo-Wilcox aquifer in northwestern Louisiana

Groundwater resources in northwestern Louisiana may be needed for development of natural gas production from the Haynesville Shale. Use of groundwater for hydro-fracturing of the shale may lower water levels and alter groundwater flow directions in the Carrizo-Wilcox aquifer and other local aquifers. Regional maps of aquifers in northwestern Louisiana are unavailable. The LaWSC, in cooperation...

Hurricane Information

Hurricanes bring destructive winds, storm surge, torrential rain, flooding, and tornadoes. A single storm can wreak havoc on coastal and inland communities and on natural areas over thousands of square miles. In 2005, Hurricanes Katrina, Rita, and Wilma demonstrated the devastation that hurricanes can inflict and the importance of hurricane hazards research and preparedness.

Developing Techniques for Estimating Nutria (Myocastor coypus) Abundance

Nutrias (Myocastor coypus) are an aquatic rodent imported from South America to the United States in the 1920-40’s for the fur farms. Since their original importation they have become established in the wild in many regions of the United States.
