Revegetating After a Wildfire

It was in June 2013 that the 3,200-acre Royal Gorge fire broke out near Cañon City, CO, situated about 45 miles southwest of Colorado Springs. The wildfire destroyed almost everything in its path (48 out of 52 structures in Royal Gorge Park were lost), although surprisingly it spared the Royal

Silt Management

Silt Management

Siltation in water containment structures is problematic, resulting in the loss of space in tanks and other structures such as reservoirs, ponds, and catch basins. It also increases the cost of treating drinking water, with high loads interfering with coagulation, filtration, and disinfection.

“The Base Could Liquefy”

Of all the problems we hear about related to American infrastructure, the state of the nation’s dams is perhaps the scariest; a failure upstream of an urban area could cause more damage all at once than just about any other infrastructure-related event. The failure of the spillways at the Oroville

How to Control Sediment Erosion on Construction Sites

How to Control Sediment Erosion on Construction Sites

Work on the average construction site disrupts many cubic yards of dirt. All of that disrupted soil poses a big sediment control challenge. Given the unpredictability of storms and rainfall, controlling sediment requires vigilance. It also adds to the cost of construction projects. But if sedimentation is not controlled, the
