In order to highlight the evolution of environmental quality parameters and especially the evolution of this process and to achieve a set of procedures for improvement of some necessary steps to optimize the system of observation and action in time we propose this study. In the last three years a study has focused on the drawing of a rich map of data for the quality of surface water of the DanubeRiver was developed and the main idea was to consider a great set of data and to organize them in a mathematical model in order to have an exhaustive image of the evolution of the water quality in time. Modelling this database using specific results which belong to numerical mathematical analysis was a desire of ours and the results can be used now in order to present an evolution, to make prediction and to consider the DanubeRiver like a human e...

In the future, it is expected that the role of computers in our life become essential; any student will have to master this field in order to achieve easily what he wishes.

The support for this attitude could be the GeoGebra-software. The software has made some important steps in order to cover the need of modeling the mathematical space, thus one could accept that any transition could be made towards Geography in order to offer a wider perspective upon the Earth`s spectacle. Even if this geographical environment is represented by maps or stereoscopic images, the connection between Geographical studies, Mathematics and GeoGebra-software in the sense of investigation, becomes more and more accepted today. This study is a window that develops a method of investigation and opens some trends in didactics, focused to GeoGebra.

The comprehension and effective application of mathematical models in studying environmental phenomena keep up with the results in the domain of mathematics and the development of specialized software as well. Integrated software programs simulate and predict extreme events, propose solutions, analyzing and processing data in due time. This paper presents a browsing through some mathematical categories of processing the statistical data, examples and their analysis concerning the degree of water pollution downstream the river Danube.

One such software soft is GeoGebra. The software is free and multi-platform dynamic mathematics software for learning and teaching, awards in Europe and the USA. This paper describes some critical but constructive investigation using the platform for graph functions and dynamic geometry.
