Interactive map of real-time flood information for Texas

The U.S. Geological Survey's Water On The Go app provides real-time information on stream flows, lake levels, and rainfall in Texas. The app automatically finds data near your current location (or any chosen location in Texas) for rapid access to water information. Special icons indicate rapidly rising streams and lakes or heavy rain that may pose a flood risk.

Users can click on individual sites for current water levels, a graph of levels in recent days, and links to more data and information about the site.

ASCE Shares Member's Reflection on Post-Maria Puerto Rico #HurricaneMaria

Puerto Rican residents walk in flooded streets in Condado, San Juan, Puerto Rico.
The American Society of Civil Engineers shared a dispatch from one of their members and her reflections on Puerto Rico's infrastructure from an engineer's perspective following Hurricane Maria. She shares how collapsed roads are affecting communities, and trips to buy gas can take all day. Read her account here.

Building the Modern World: Geoscience that Underlies our Economic Prosperity

Wednesday, August 2, 2017

Geoscience information is integral to the strength and growth of communities and provides the resources for economic growth. All building materials, energy resources, construction projects, and hazard mitigation efforts are fundamentally based on geoscientific data and the geoscience workforce.

Our speakers are:

Key topics to be addressed include:

  • The industrial materials and minerals used to construct buildings/infrastructure
  • The importance of readily available construction materials and the resulting demand for mines and quarries throughout the U.S.
  • How geoscience is used to determine whether or not sites are suitable for infrastructure development
  • How geoscience is used to help guide design and construction to enhance the quality of life, economic strength, and physical security of coastal areas

Webinar Co-sponsors:
American Association of Petroleum Geologists; American Geophysical Union; Consortium for Ocean Leadership; Geological Society of America; National Ground Water Association; National Science Foundation; Soil Science Society of America

    Interactive map of sea level rise impacts in Delaware

    The Delaware Sea Level Rise Inundation map shows how various extents of future sea level rise (0.5, 1.0, and 1.5 meters) would affect flooding in coastal Delaware. For each scenario, users can see the areas that would be flooded during an average higher tide (Mean Higher High Water). The map does not include the effects of erosion, subsidence, or future construction.

    Users can search by location to see the effects on individual areas.

    How do pyrite and pyrrhotite damage building foundations?

    Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides. As they grow, the new sulfate minerals push against the surrounding rock, causing it to swell and crack. This causes damage in two main ways:
