Science to support the understanding of south Texas surface-water and groundwater resources in a changing landscape
Short descriptions of the research and monitoring activities we are carrying out to assist state, local, and Federal agencies dealing with water resource issues in the southern part of the state.
SPARROW Modeling of Surface-Water Quality
A software model for regional interpretation of water-quality monitoring data, estimating origin and fate of contaminants in streams, with documentation, publications and data for the applications.
Visualization of flow alternatives, Lower Missouri River
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.
Watershed modeling
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
Watershed modeling applications in south Texas
Explains how mathematical simulations of watershed properties can help us understand the likely behavior of the water systems, putting the choices available to people in better perspective.
Watershed processes and modeling
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.
A Magnitude 7.1 Earthquake in the Tacoma Fault Zone-A Plausible Scenario for the Southern Puget Sound Region, Washington
Scientific description of the likely effects of a significant earthquake on this densely populated area.
Acid Rain in Shenandoah National Park, Virginia
Explains acidity and acid rain and how it affects aquatic organisms. Describes the effect of acid rain on this national park, identifying areas that are at greater or lesser risk from acid rain.
Anticipated effects of development on habitat fragmentation and movement of mammals into and out of the Schoodic District, Acadia National Park, Maine
Wildlife you see in a national park or other reserved area don't know about the park boundary. Bobcat, martens, mink, and moose need different types of living space and habitat. Development outside the park affects their ability to inhabit the park.
Application of the SPARROW watershed model to describe nutrient sources and transport in the Missouri River Basin
Maps and diagrams showing how the mathematical model predicts the distribution of various pollutants within a large watershed.
