## HeapSim2D – A 2D axisymmetric model of heap leaching under …

1.Introduction. Significant progress has been made towards understanding the fundamentals of heap leaching over the last twenty years, including the development of many excellent mathematical models (as reviewed by Dixon (2003) and Marsden and Botz (2017)).However, relatively little work has been devoted to the problem of heap hydrology under drip emitters.
