SUMMARY The main objective of this thesis is to use SiWaPro DSS to model and simulate the water flow process in the unsaturated zone with the available data from the lysimeter number 302 in Juelich, Germany The unsaturated zone is the portion of the subsurface above the ground water table It contains air as well as water in the pores This zone plays an important roll in many aspects of hydrology, such as infiltration, exfiltration, capillary rise, recharge, interflow, transpiration, runoff and erosion Interest in this zone has been increasing in recent years because the movement of water along with contaminants in this zone have been affecting the groundwater and the subsurface environment Water flow is concerned with movement of water in unsaturated porous media In order to handle water flow process under steady state or transient conditions in the unsaturated zone, a useful computer program is used to model and simulate this process This program combines the simulation module SiWaPro for numerical modeling of water flow and contaminant transport in variably saturated media with additional simulation and parameter estimation tools, data sources for the simulation and a graphical user interface The computer-based decision support system SiWaPro DSS software is a program for modeling and simulating the processes as water flow, solute transport, bio degradation and sorption in variably saturated porous media In SiWaPro DSS, the discretization of the modeling area is realized using finite elements with the GALERKIN method SiWaPro DSS contains the 2D triangular mesh generator EasyMesh 1.4 The mesh generator allows the generation of meshes with varying element sizes and irregular mesh boundaries Currently, the generator allows flexible space quantization at modeling time given by the user To validate SiWaPro DSS, the means of measurement data from a lysimeter experiment are used Lysimeters are devices for measuring the characteristic properties of the soil water balance, amounts of seepage water and their quality In this thesis, lysimeter 302 located in Juelich, Germany is used for calibrating model The Juelich lysimeter 302 was established in August 2001, the monoliths were taken out from Munich-Neuherberg in June 2001 and the installation of the measurement devices occurred and the data logging started on December 10th 2001 This lysimeter is run by the Research Centre in Juelich (FZJ) This lysimeter is a large undisturbed lysimeter with 2m2 in area and 2,4m in depth including 0,8m of reference material The three suction cups are installed together with tensiometers, TDR and temperature sensors at 3-different depth layers distance from upper edge of the lysimeter in turn as 0,85m; 1,15m and 1,8m To model the water flow of the lysimeter in SiWaPro DSS, the finite element mesh of the lysimeter is constructed with the column of 1,6m in width and 1,6m in height (excluding 0,8m of reference material) The lower boundary condition is a first kind boundary condition that allows outflow only A second type boundary condition is applied at the upper boundary of the column of lysimeter It is a transient boundary condition using time – variable boundary conditions to simulate precipitation in the model Three soil water sampling device layers are applied as first kind boundary condition, and as the lower boundary condition, only outflow is allowed The column of the lysimeter soil is divided into layers; each of the soil layers is described in its hydraulics with 11 parameters To calibrate model, two data sets of 11 soil hydraulic and van Genuchten parameters with different initial pressure head and boundary condition of three suction cup layers as well as different amount of nodes and elements in the mesh are used Because the time is short – besides, one model took from 25 hours to 50 hours for running; some models took much more time, then they were stopped before they finish So there are only 10 models were run After getting the result from simulation of each model, the simulation result was checked and analyzed and then the data set was changed or finite element mesh of the lysimeter was adjusted or the software was reconsidered The simulation results that were shown in diagrams in section 4.1 are the best model, but the results still show some difference of output between simulation and measurement because input data which took from lysimeter station are not well documented and some soil parameters which are estimated by the person who operate the lysimeter are different from the fact The result shows that total inflow and total outflow of lysimeter are in balance That means the model and finite element mesh of the lysimeter is designed well Outflow of the suction cup layer number in the simulation is almost the same as measurement Outflow of the suction cup layer number and lower boundary condition in simulation are the same as measurement in the first year But in the second year, outflow of the suction cup layer number in simulation is higher than measurement; opposite to the outflow of the lower boundary condition the simulation one is lower than measurement Outflow at the suction cup layer number is different increasing by time between simulation and measurement The differences come from the data mentioned as above The SiWaPro DSS program have been introducing to Federal Environmental Bureaus and Consulting Companies in Germany These Bureaus and Companies can use this software tool primarily for leachate forecasts with respect to the German soil protection law In Vietnam it also can be apply similar to Germany, but it takes a bit time for Vietnamese to familiar with it For Vietnamese to apply this software, the GUI and help system were initially translated into Vietnamese Therefore, it can be said that SiWaPro DSS is one of the useful tools for leachate forecast However, it should be applied for a wide variety of contaminants if the software is revised to adapt with not only all available data but also a few available data The lysimeter is good for calibrating the model and will be better if the data is documented well and
