Upcoming interagency study to assess status of ecological conditions, their relationships with contaminants and nutrients, anthropogenic factors affecting these, and develop models that may predict these ecological conditions.
Homepage describing The National Map, which will produce a seamless, continuously maintained set of public domain geographic base information, with links to map viewer, pilot projects, reports, fact sheets, and national atlas.
Techniques of computer-based representations of areal geology to construct three-dimensional geologic maps that retain all the information of traditional geologic maps while providing a more detailed picture of the subsurface.
To assess the effectiveness of ecological carbon sequestration, we plan to define ecosystem reporting units, model baseline and potential carbon sequestration, develop spatial models that simulate ecosystems, and integrate remote sensing data.
The primary goal of U.S. Geological Survey (USGS) Natural Hazards Response is to ensure that the disaster response community has access to timely, accurate, and relevant geospatial products, imagery, and services during and after an emergency event.
Types and quantities of raw materials used by U.S. manufacturers and consumers, which have changed significantly as the economy has moved from one that is predominantly agricultural to one that is primarily industrial.
Usually we choose to put water monitoring stations in places where we have no data already. But it's more efficient to place stations so that they help to reduce uncertainty in the results of modeling. This analysis shows how to choose.
This report presents a visual, statistical presentation of five modeled flow-management alternatives and two reference alternatives for four selected sites on the Lower Missouri to aid in decision making for flow management of the river.
Brief description of project for the Federal Emergency Management Agency to prepare and modify Flood Insurance Rate Maps based on flood frequency analysis, ground surveys, and flood profiles in Virginia.
Description of the development and use of models to study watersheds supporting a broad range of applications and user skills. Includes links to related memos, training, software, projects, and references
Links to published materials produced by the Watershed Processes and Modeling Project on watershed model TOPMODEL, compilation of STATSGO soils data, climate change, landscape heterogeneity in ecoregions, and other links.
The U.S. Geological Survey uses remote sensing to improve fire-management databases in the Everglades, gain insights into post-fire land-cover dynamics, and develop spatial and temporal fire-scar data for habitat and hydrologic modeling.
