Dr. Mater is a civil engineer with Alden Labs hydraulic modeling group located at the Fort Collins, Colorado office. His particular expertise is in three-dimensional numeric modeling of hydraulic structures related to water supply, fish passage, river mechanics and restoration, sediment transport, and turbulent mixing in stratified environmental flows. Ben’s background ranges from the restoration of headwater streams to the development of turbulent mixing schemes in NOAA’s global ocean model. Since being at Alden, Ben has focused primarily on the application of computational fluid dynamics (CFD) to solve fish protection and passage problems as well as investigating CFD’s role in solving sediment transport issues. Ben also enjoys blending personal and professional interests as an avid whitewater kayaker.
