Magma Flood Retarding Structure – Dam Break Analysis

  • Client LeSueur Investments/Magma Flood Control District

  • Location Florence, Arizona

  • Services Modeling and Study

Project Highlights

  • MFRS has been deemed unsafe by the Arizona Department of Water Resources Computer model results that show the flood boundary, depth, and timing at downstream areas

  • 25 square miles studied

  • Failure modeled under a 100-year 6-hour storm event condition, a probable maximum flood (PMF) condition, and a “sunny day” condition

  • Predict the dam break flood wave peak flows, peak flood elevations

  • Inundation boundaries and depths

  • Flood front travel times at specified downstream locations
