Hydrologic Evaluation of Landfill Performance
- Hydrologic Evaluation of Landfill Performance
The HELP model (Hydrologic Evaluation of Landfill Performance) is a hydrologic numerical model initially developed by the United States Environmental Protection Agency for landfills.[cite book |author=Schroeder, P.R. and Dozier, T.S. and Zappi, P.A. and McEnroe, B.M. and Sjostrom, J.W. and Peyton, R.L. |year=1994 |title=The Hydrologic Evaluation of Landfill Performance (HELP) model: Engineering documentation for version 3 |publisher=U.S. Environmental Protection Agency Office of Research and Development |location=Washington, DC] The model uses a water-balance approach to model evapotranspiration and drainage through soil layers.]Versions
