Mapping Water Resources in Guam


Today I'm joined by Dr. Leroy Heitz, who is professor emeritus at the University of Guam.  We discuss all the different ways he has mapped water in Guam.  

Topics include:

  • Potable water and hydraulic engineering.
  • Waste water and septic tank mapping.
  • Modeling watershed runoff.
  • Erosion calculations using drones.
  • Salt water intrusion.
