The best material to build a 2km dam on...

has to be water-soluble gypsum (nl: gips). They did it in Iraq in 1983! The Mosul Dam:

  • Mosul Dam is Middle East's fourth largest dam in reservoir capacity and Iraq's largest
  • Key component in Iraq's national power grid, with four 200 megawatt (MW) turbines generating 320 MW of electricity a day
  • Built on water-soluble gypsum, which causes seepage. Subsequent erosion creates cavities beneath dam that must be plugged or "grouted" on a regular basis or dam will fail, say experts
  • Array of piezometers have been deployed to measure water pressure and leakage
  • Seismic equipment provides information to monitor dam's stability

    I hope this guy isn't like the previous Iraqi information minister.
