• 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.
