software_title: "Code System Calculate One-Dimensional Vertical Transport Unsaturated\
  \ Soil Zone"
acronym: "SESOIL"
doi: "https://doi.org/10.11578/dc.20180618.16"
description: "SESOIL, as an integrated screening-level soil compartment model, is\
  \ designed to simultaneously model water transport, sediment transport, and pollutant\
  \ fate. SESOIL is a one-dimensional vertical transport model for the unsaturated\
  \ soil zone. Only one compound at a time can be considered. The model is based on\
  \ mass balance and equilibrium partitioning of the chemical between different phases\
  \ (dissolved, sorbed, vapor, and pure). The SESOIL model was designed to perform\
  \ long-term simulations of chemical transport and transformations in the soil and\
  \ uses theoretically derived equations to represent water transport, sediment transport\
  \ on the land surface, pollutant transformation, and migration of the pollutant\
  \ to the atmosphere and groundwater. Climatic data, compartment geometry, and soil\
  \ and chemical property data are the major components used in the equations. SESOIL\
  \ was developed as a screening-level model, utilizing less soil, chemical, and meteorological\
  \ values as input than most other similar models. Output of SESOIL includes time-varying\
  \ pollutant concentrations at various soil depths and pollutant loss from the unsaturated\
  \ zone in terms of surface runoff, percolation to the groundwater, volatilization,\
  \ and degradation. The February 1995 release corrects an error that caused the code\
  \ to fail when average monthly air temperature was -10C and includes an improved\
  \ iteration procedure for the mass balance equations in the model. PLEASE NOTE:\
  \ The RISKPRO information management software (see OTHER PROG/OPER SYS INFO) was\
  \ used by the developers of the New SESOIL User's Guide in their study and revisions\
  \ of SESOIL. Using RISKPRO in conjunction with SESOIL is an option, and it may provide\
  \ the easiest way to use SESOIL. The other option, use of SESOIL in stand-alone\
  \ mode, has been tested and used. The stand-alone option is covered in ''Instructions\
  \ for Running Stand-Alone SESOIL Code'', and in ''A Seasonal Soil Compartment Model''."
