FINALLY! Desktop Drainage Studies You Can TRUST

See how the proliferation of publicly available LiDAR topography data and 2-Dimensional hydraulic modeling have enabled dependable desktop drainage studies and are saving pre-engineering dollars:

LiDAR data is your friend

Did you know? LiDAR topographic data is publicly available in many areas across the U.S. and many data sets have a vertical accuracy of <0.3 feet, making them ideal for use in high-quality desktop drainage studies. New LiDAR coverage areas are becoming available monthly.

"2D, or not 2D, that is the question"

Two-dimensional (2D) hydraulic modeling is replacing one-dimensional (1D) modeling and is becoming the industry standard. Don't just take our word for it; see this 2-minute video from the Federal Highway Administration (FHWA) that explains why. High-resolution topographic data, which LiDAR provides, is essential for using 2D models in high-quality desktop drainage studies.

And the Results?

Desktop drainage studies that utilize LiDAR and 2D modeling can help you economically answer these questions and others without having to 'put boots on the ground': Can I 'pipe and fill' that bridge? Can I slip-line that corroded culvert before it fails? Is my drainage structure adequately sized? Where do I need to install pipes or a bridge to prevent a washout the next time?
