decision support system for leachate forecast
Duration:
10/2001 - 12/2007

Description:
The software SiWaPro DSS is based on the software SWMS_2D
(Simunek et al., 1994), which itself is a predecessor of the
well-known HYDRUS-2D software (Simunek et al., 1999). SiWaPro
DSS simulates 2D-vertical-plain or 2D-rotationally-symmetric
flow and transport processes in the unsaturated soil zone using
finite element discretization. Flow processes are described
with the Richards equation, augmented with terms for root water
uptake. Simulation of transport processes is based on the
numerical solution of a convection-dispersion-equation,
augmented with terms for sorption and degradation.
It is a one-component-model. In comparison to SWMS_2D SiWaPro
DSS offers a flexible choie of boundary conditions, the
consideration of processes which are subject to hysteresis in
the unsaturated soil zone and an integrated parameter
identification algorithm.
The simulation kernel is written in FORTRAN, with some parts
being parallelized using OpenMP to use computer hardware with
multiple processors more efficiently.
The software was significantly enhanced in the BMBF project
"Sickerwasserprognose" and equipped with a multilingual
graphical user interface. It runs on Windows XP or newer
Microsoft operation systems.
