Abstract

The Decision Support System MINE has been developed for the analysis of regional water policies in open-pit lignite mining areas. It is based on a two-level model approach. The first-level planning model is used for the estimation of rational strategies of long-term development applying dynamic multi-criteria analysis. Therefor simplified submodels are used for a rough time discretization (yearly time steps and larger). The second-level management model considers managerial/operational aspects for shorter time steps (monthly and yearly) employing more comprehensive submodels. It is a classic simulation model. For selected submodels stochastic simulation (Monte Carlo method) is used in order to consider random inputs (e.g. hydrological inflow and water demand). This model serves for the verification of strategies obtained in the planning model, for the verification of simplified submodels used in the first-level model, and for the specification of strategies.

Starting with the description of the position of the management model within the DSS MINE the structure of the management model is given. The used submodels for surface water/groundwater interaction and water quality are described. In the Appendix computer subroutines of some submodels are given being suitable for a more general application.
