Types of rivers and their dependence of the cartographic projections, example of river Lepenica

Summary/Abstract: The river system of Lepenica was drawn by using the GeoMedia programme in projections of 1:25 000, 1:50 000 and 1:300 000. Different type of information was shown using each of these projections, because smaller projections show more general information, and vice versa. Using the Horton, Strahler and Schrewe Methods we were able to divide rivers into types according to their sizes. We are also able to show the density of river network as well as their physio-geographical characteristics due to their dependence on each other. Big influence on the current appearance of the river network is due to one of the physio-geographic factors called geology. Geological composition of the Lepenica flow is very convoluted. This convolution is mainly based on their origin but it’s also stratigraphical. Based on the division of rivers into their types we are able to calculate the number of watercourses, based on the Schrewe Method. Using this method we can also make conclusions with regards to density of river network. Placing the rivers into different classes is mainly used as the basis of watercourse comparisons. These methods are not only used in hydrology, but also in many other scientific areas.
