• Abstract:
  The research team at the University of New Mexico’s (UNM) hydraulics lab designed, constructed, and ; tested a 1:20 scale physical model of a proposed culvert in Jemez Springs, New Mexico. The culvert ; design was developed by the New Mexico Department of Transportation (NMDOT). The culvert ; receives supercritical flow from the Church Canyon Arroyo. As a result of existing structures, complex ; arroyo planform, and variable slopes, the culverts response to a supercritical flow regime was difficult ; to know. Therefore, physical modeling was performed. ; The UNM research team tested the culvert’s capacity and ability to reduce velocities to match existing ; conditions. This included evaluating HEC 14 roughness element design and proposing alternatives. ; Researchers determined that NMDOT design performed sufficiently, conveying 100-year flows and ; reducing velocities. UNM researchers also propose a design alternative that has fewer roughness ; elements and roughness elements in fewer culvert sections, allowing for easier maintenance. The ; modeling process and results have been discussed in this report.
