Engineers often begin projects with the following questions: when it rains, how much water infiltrates into the soil, how much water runs off, and how quickly does this water travel?

This exercise helps us to adequately size new infrastructure, develop safer building codes, and protect communities from flood hazards. Though there are many ways to evaluate the impacts of stormwater, the foundation of any of these methodologies is an understanding of...

    The National Hurricane Center predicted that Gordon would make landfall as a hurricane Tuesday night. Hurricanes Harvey (which inundated Houston in August 2017) and Maria (which devastated Puerto Rico last September) illustrated the destruction and disruption that storms can cause. Some of the damage is immediate, and some lingers for months and years. While storms can’t be controlled, taking precautions can help reduce risks and avoid injuries.

    A rich array of resources is...

    Just as trees’ inner rings tell the story of their growth, their roots can reveal how quickly the earth is washing away around them. It’s critical information for addressing watershed problems.

    Freese and Nichols’ Bryan Dick, left, and Ian Jewell, right, not only adapted a method for reading exposed tree roots to measure rates of riverbank erosion, but our team is using the technique for a growing list of clients.
