Register now for this upcoming Critical Issues Webinar! July 6, 2017 at 1:30pm EDT. 90 minutes.
 
This special 1.5 hour-long AGI Critical Issues webinar will focus on efforts to anticipate, mitigate, and respond to coastal storms, erosion, and associated hazards at the federal, state, and local level. Speakers from California, Texas, and Georgia will discuss the impacts of coastal storms and erosion, tools used for coastal hazard mitigation planning in their regions, and examples of community engagement and coordination.

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:

Planning for Coastal Storm and Erosion Hazards

Thursday, July 6, 2017

Coastal hazards are a widespread challenge that cost millions (and sometimes billions) of dollars in the U.S. every year due to property loss and spending on mitigation measures. Based on the most recent U.S. Census, over 39% of the U.S. population lives in areas that may undergo significant coastal flooding during a 100-year flood event1. Additionally, six of the ten most expensive weather-related disasters in U.S. history have been caused by coastal storms1,2. Reducing risk and responding to coastal hazards is an ongoing challenge that relies on close coordination and cooperation between geoscientists, coastal planners, emergency managers, and communities at all levels.

An introductory talk and three case studies from around the U.S. cover coastal storm and erosion hazards in the U.S., as well as examples of coastal hazard planning from the Pacific, Gulf, and Atlantic coasts, with a focus on how geoscience informs planning at all levels. Speakers from California, Texas, and Georgia discuss the impacts of coastal storms and erosion, tools used for coastal hazard mitigation planning in their regions, and examples of community engagement and coordination.
