2D Modeling and Matrix Riprap Save Millions on Transportation Flood Recovery Projects
By Will DeRosset, PE, CFM, and Anthony Alvarado, PE, CFM The Colorado Department of Transportation recently published several case studies celebrating major progress in effective design in flood recovery projects. The projects all relate to designs implemented in the recovery from devastating 2013 flooding. The key takeaways are: 2D hydraulic modeling and spatially explicit analysis… Read More »

Can Mapping Save Lakes from Perils of Soil Erosion?
By Zachary Nienow, GISP Culvert mapping and culvert asset management have been hot topics at the local, state, and even federal level lately. Runoff from rainfall events can carry nutrients away and transport soil to rivers and lakes. Site-specific and watershed-based factors can impact erosion, leading to sediment loading and other water and aquatic habitat… Read More »
