To download the Overtopping Performance Testing brochere, click HERE! Colorado State University (CSU) has four Overtopping Facilities which are part of a unique research center designed for hydraulic model studies, testing and calibration in the fields of open channel and closed conduit hydraulics. The overtopping facilities at the Engineering Research Center provide a wide range of sizes and capacities to meet any project need (Table 1). Two of the overtopping facilities, the 10-ft and the 6-ft mild, are located outdoors; while the 6-ft steep and 4-ft are located indoors. Outdoor facilities are supplied with water from Horsetooth Reservoir by a 36-inch diameter pipeline. Average static head to the system throughout the year is approximately 200 feet. Reservoir water quality has a very low turbidity and a water temperature ranging from 40 to 55 degrees Fahrenheit. Indoor facilities are supplied by individual pumps in conjunction with a one acre-ft sump located beneath the laboratory floor. The ability to test year around is the inherent benefit of indoor facilities. |

To download the Erosion Control Performance Testing brochere, click HERE! Colorado State University has pioneered the use of Planter Box Technology. Using mobile boxes to house vegetated plots allows multiple plots to be grown and tested in a single season. Planter Box Technology reduces the cost and time associated with testing vegetated reinforcement systems. 
For over 50 years, Colorado State University (CSU) has been a leader in the erosion control industry. Our professional staff has over 100 years combined experience in erosion control research including performance testing of vegetated and unvegetated erosion control products under channelized, overtopping, and pipe outlet conditions. CSU partners with a multitude of agencies and private companies to facilitate applied erosion control technology. Erosion control performance testing continues to be an area of industry interest. With the development of many new testing protocols and an abundance of new products, performance testing has become a vital component of product development. CSU is meeting the industry’s need for performance testing with expert staff, and state-of-the-art facilities and equipment. Our laboratory uses cutting edge data collection instruments to provide a variety of high quality data. The specialized instruments available include a multitude of velocity instruments that measure mean and instantaneous velocities in 1-D, 2-D, or 3-D. In addition, our laboratory has an ultrasonic ranging system that provides real time scour monitoring and mapping, and a high frequency laser scanning system which allows full pre-test and post-test topographic surveys.
