Quantitative analysis of drainage network direction in the Bükkalja

Abstract

Quantitative analysis of stream-order is not a new thing in the study of drainage basins and river systems. The essence of the method is to consider the source branches as first-order, and then from the meeting of two first-order valleys a second-order valley is born (so on…). Valleys of the same order increase order by one, while the encounter of two valleys of different order does not increase order. Analysing the stream-order, we can draw conclusions about the size of the given valley section, its role in the river system, and even its age. In my work I examined the order of the valleys running in Bükkalja and their direction and I compared my findings with the results published in the literature so far.
