I use WIKI 2 every day and almost forgot how the original Wikipedia looks like.

From Wikipedia, the free encyclopedia

SEEP2D is a 2D seepage analysis program written by Dr. Fred Tracy of the United States Army Corps of Engineers. The program is used to analyze water seepage, typically through dams and levees or under  sheet piles. "The model is internationally known in the engineering community as a model for complicated seepage analysis of dams and levees."[1] It has been shown to have acceptable accuracy compared with experimental results.[2]

  • Automatic mesh truncation on phreatic surface (optional)
  • Flow modeling in both saturated and unsaturated regions (optional)
  • Support for nonhomogeneous and anisotropic soil conditions
  • Output of total head, flow vectors
