Stream Ecology
Who lives in your stream? Rivers and streams, even small ones, are teeming with a vast number of species, including fish, aquatic invertebrates, and algae. Stream ecology is the study of those aquatic species, the way they interrelate, and their interactions with all aspects of these flowing water systems.
Flood Inundation Mapping Science
When planning for a flood, there are three key questions that must be answered: What areas will be flooded? How deep will the flood waters get? When will the flood arrive? Historical flooding can help a community anticipate how much impact similar flood events could have, but there are other methods and tools that can provide more accurate and nuanced estimations of a wide variety of flood...
Flood Inundation Mapping (FIM) Program
Floods are the leading cause of natural-disaster losses in the U.S. More than 75 percent of declared Federal disasters are related to floods, and annual flood losses average almost $8 billion with over 90 fatalities per year. Although the amount of fatalities has declined due to improved early warning systems, economic losses continue to rise with increased urbanization in flood-hazard areas.
Facts About Water
Yes, of course the most obvious fact about water is that it is wet, at least in the liquid state. But, there are many more facts about water that make it a most fascinating substance, one that all life on and in the Earth depends on.
Gold King Mine release (2015): USGS water-quality data and activities
On August 5, 2015, U.S. EPA was conducting an investigation of the Gold King Mine near Silverton, Colorado. While excavating as part of the investigation, water began leaking from the mine tunnel, and about three million gallons of water and sediment were released into Cement Creek, a tributary of the Animas River. The USGS provided pre- and post-release water-quality and streamflow data from...
Aqueous Crystal Growth and Dissolution Kinetics of Calcium Carbonate Minerals at the Amarigosa Desert Research Site, Nevada
The USGS studies calcium carbonate mineral reactions in soils at the Amarigosa Desert Research Site (ADRS) near Beatty, Nevada, in order to better understand carbon dioxide transport to and from the soil surface, as well as sequestration of toxic elements in the soil.
Aqueous Crystal Growth and Dissolution Kinetics of Earth Surface Materials
Although calcium carbonate reaction kinetics has important application in several areas of Earth Science, the mechanism of natural organic matter mediation of carbonate minerals growth and dissolution rates remains largely unknown. This project uses multiple approaches to study calcium carbonate formation and dissolution rates in surface water and groundwater systems.
