GEMSS model in the project
The GEMSS® (Generalized Environmental Modeling System for Surfacewaters) model, created by Environmental Resources Management (ERM® Inc. Exton, PA, USA) is a three-dimensional and multi-functional mathematical model for surface water environment modelling. The motivation for the introduction of a new solution to the list of prognostic models is mostly related to the uniquely broad spectrum of application of this model to various environmental matters (Fig. 3) as well as its calculation and presentation capabilities. It is also a model which can be easily incorporated in the environment management system, is commonly used around the world and accepted by the World Bank and many American government agencies, including the Environmental Protection Agency (EPA).

GEMSS® models family: modules (from the top left corner): sediment transport (STM), hydrodynamic (HDM), petroleum and chemical leakage pollution (COSIM), spreading of toxic substances (TOX), thermal analysis of reservoirs (TAM), water quality (WQM), CE-QUAL-W2 module (two-dimensional hydrodynamic and water quality model, predecessor of GEMSS®), river module 1D. Source: GEMSS® software.
The central calculations “machinery” of the GEMSS® model are four hydrodynamic modules: 3-D model GLLVHT, 2-D model CE-QUAL-W2, 1-D model GLHT and 0-D model RTC. Modules presented in figure 3 are fully compatible with the hydrodynamic package and are successively supplemented with new applications, such as the suspended matter transport module (PTM), bacteria (GBM) and algae (GAM) distribution module.
Each of the modules has a user-friendly set of tools including: simple creation of grids, full compatibility with ArcGIS, “field” database with possibility of visualisation and analysis, pre-process management of data on the boundary conditions of the model as well as post-process graphic processing, 3D animation and statistical analysis of the modelling results. These features make the GEMSS® family models functional elements of the whole system of information and management of environmental resources.

The detailed objectives and scope of the MONSUL Project are as follows:
- installation and commissioning of a measurement system for the assessment of reservoir water quality (floating on the surface of the reservoir and transmitting on-line data to a computer). The following parameters will be monitored: water temperature, pH, oxygen concentration, salination, chlorophyll concentration, Ntotal and Ptotal.
- development of a GIS database for the Sulejów Reservoir area,
- development of a 3D model of the Sulejów Reservoir. The model will enable calculations of temperature gradients, flow rates and pollution concentrations as well as the simulation of the ecological condition of the reservoir,
- publication of the results via the website, magazine articles as well as meetings and seminars.
